General Safety Instructions  
Intended use  
Your Street Machine GT is a bicycle for the  
use on streets and surfaced roads.  
Legal requirements  
When you ride your bike on the public road it  
must comply with national legislation and gui-  
delines.These will vary from country to coun-  
try.  
This bicycle is not designed for the use in ra-  
cing and off-road riding, for jumping or acroba-  
tics, and you must not ride across kerbs, stairs, In general, there are minimum standards for

servation of the prescribed usage and mainte-  
nance regulations and instructions.  
In most countries, including Germany and the  
UK, two independent braking systems are re-  
quired. Do not ride with only one brake wor-  
king!  
The first miles  
The first 300 km are an important phase in  
which you break in the bicycle. During the first  
use of a new bicycle the screws may bed in  
and come loose. Cables and spokes may  
stretch. Please be very attentive during that  
period.  
Please contact your local dealer to find out ab-  
out your legal obligations.  
After 300 km or after two months at the la-  
test you will have to take your bicycle to a bi-  
cycle mechanic for the first service. Please re-  
cord this first service and the tasks performed  
in the warranty pass on page 57.This first ser-  
vice is the prerequisite for further use of the  
bicycle and for your warranty claims.

General Safety Instructions  
Be careful that your luggage on the racks or in  
Load capacity  
the Speedbag is safely stored. Bags must be  
tightly fastened to the rack so they can not  
move. In no case may loose parts like straps or  
belts touch the wheels, the derailleur or the  
suspension.  
The maximum load (rider + luggage) is 120 kg  
(276 lbs).The maximum total weight (bicycle +  
rider + luggage) is 140 kg (322 lbs).The lower  
limit is valid. It is important to adjust the  
spring stiffness of the suspension according to  
the load, see the chapter about adjusting the  
suspension in this manual, page 16.  
We recommend waterproof bicycle bags by  
the German manufacturer ORTLIEB.You can buy  
them with extra large hooks matching the  
oversized tubes of the rack.You can also refit  
those large hooks later.  
Carrying luggage  
Luggage transport is only allowed with the  
special rear racks, lowrider racks and luggage  
boxes offered by HPVelotechnik .  
Take care that your luggage does not cover  
the lighting system and the reflectors of your  
bicycle and that they stay fully functional.  
Maximum load:  
Rear rack 25 kg (57 lbs)  
Lowrider under the seat 25 kg (57 lbs)  
Luggage box (Speedbag) 10 kg (23 lbs)  
In case you want to park your bicycle take ca-  
re to lean it on a wall or any other solid ob-  
ject.With the kickstand alone it is not possible  
to safely park a bicycle loaded with luggage, it  
could fall down and be damaged.  
When a rear rack or a Speedbag is mounted  
you have to make sure that when the rear sus-  
pension is fully compressed there is at least a  
1
1 cm ( /3") distance between the rear tire or  
mudguard and the rear rack. If you want to in-  
crease this distance you have to decrease the  
suspension travel of the rear suspension ele-  
ment with clip-on spacers. For that purpose  
please consult your local dealer.  
Additional loading can influence thehandling of  
your bike considerably. If you plan on riding  
with heavy luggage we advise you to make a  
test ride on a street with no traffic to adjust  
to the new situation.  
The load should be placed as close to the bo-  
dy of the rider as possible, since this leads to a  
more stable performance.You can also impro-  
ve the handling of the bike by positioning the  
center of gravity of the luggage as low as pos-  
sible, so pack heavy items in the bottom of  
your panniers. Hang heavy panniers on the lo-  
wrider rack preferably to the rear rack.

Transport in the car  
Added parts and accessories  
Additional accessories may impair the function  
of your Street Machine GT.We advise you to  
generally ask your dealer before you mount  
any special parts or accessories to your bicy-  
cle.  
The best way of transporting your bicycle is  
inside the car. See that it does not lie on the  
derailleur.  
If you want to transport it outside the car we  
recommend a roof-rack or a rear carrier.Take  
care to fasten your bicycle at the frame only.  
Caution! Mounting additional parts or ac-  
cessories is at your own risk. It is important  
that you carefully read the installation guide  
of the manufacturer.Additions to the handle-  
bar like fairings, handlebar fittings, bottle hol-  
ders, etc. may impair your safety due to ad-  
ditional loading or clips with sharp edges.  
Caution! Do not fasten your bicycle at the  
handlebar or, with disassembled wheels, at  
the dropouts.The wind causes violent forces  
that can stress the parts and therefore may  
cause damage. Such damage may not be no-  
ticed immediately.  
Take care that the handlebar and the suspen-

parts to the handlebar or the seat that might  
endanger the rider through sharp edged or  
pointed shapes while steering, getting on and  
off the bike or bumping against something.  
Do not take kids with you  
The Street Machine GT is not designed for the  
transport of children.You are not allowed to  
mount a child's seat. It is only allowed to  
transport children in a trailer that has been  
specially designed for that purpose.  
Before you purchase a bell or a lighting system  
make sure that these accessories conform to  
your national laws and regulations.  
Fairings  
Trailers  
As front fairing for the Street Machine GT, you  
may use the Streamer offered by HP  
VELOTECHNIK. Please take care to assure a good  
vision over the fairing and sufficient freedom  
of movement below.  
You are allowed to use trailers up to 30 kg (68  
lbs) with the Street Machine GT. Always check  
that the suspension and the trailer still work  
properly after you have mounted the trailer.  
Take care that the trailer does not damage the  
frame in case the bicycle falls over.  
Please take into account that any fairing makes  
the bicycle more prone to crosswind influen-  
ces. In strong wind or gusts of wind unsafe si-  
tuations may occur. Please remove the fairing  
in such weather conditions before riding.

fork, drive train, suspension elements) should  
only be done with original parts by a bicycle  
mechanic, since it requires a certain degree of  
skill, suitable tools and mechanical aptitude.  
Your dealer has carefully finished the assembly,  
perhaps altered the spefication of your bike to  
meet your special requirements and perfor-  
med a test ride. Please make sure that this  
pre-delivery service is recorded in the warran-  
ty document at the end of this manual.  
Any technical change you perform on your  
own is at your own risk!  
All screws must be checked and tightened, es-  
pecially on the handlebar, stem, fork, swing arm  
pivot and wheels. Please follow the tightening  
torque settings listed in the table on page 55.  
Danger! If any part is deformed (e.g. due to  
an accident or overload), especially frame,  
fork, handlebar, seat mounts, pedals, cranks  
and brakes, it is not allowed to use it any  
further or repair it. Do not try to straighten  
bent parts.You must replace them for your  
own safety. If you do not replace a damaged  
part it can result in a total failure of the part  
and you may be seriously injured!  
Rear derailleur and brakes must be checked  
and adjusted. Please follow the instructions in  
the manuals of the parts manufacturers that  
come with this manual.  
Screws and bolts  
No alteration of parts  
Caution! Screws must be tightened with  
prescribed tightening torque. In this manual  
tightening torques are given in "Nm“  
(Newtonmeter).Always use a torque  
wrench wherever a torque setting is given in  
this manual. Never rely on "feel". Screws  
tightened too much or not enough can  
break, which can lead to dangerous acci-  
dents. In case you don't own a torque  
wrench have your bicycle mechanic do the  
respective work.You will find a table with  
the prescribed torque settings on page 55 in  
this manual.  
Caution!You are not allowed to perform  
any work on the parts of the bicycle, especi-  
ally frame, fork, handlebar and seat, which  
might endanger their solidity.  
These works include drilling holes, welding,  
brazing, paint methods that add heat or any  
other chemical treatment. If any of these  
works is done improperly it may result in a  
loss of strength through direct damage or  
increased susceptibility to corrosion.

der the main tube with a 6 mm Allen key.Take  
a grip on the front changer tube or both  
cranks and move the front boom into the fra-  
me or pull it out while cautiously turning it.  
In order to adapt the Street Machine GT as  
closely as possible to your body dimensions  
and to find the ideal seating position you need  
to adjust the front boom, seat and handlebars.  
When you pull out the front boom shift the  
chain on the smallest chain ring and sprocket  
and turn the cranks a little bit backwards whi-  
le pulling.Thus the chain is not under tension.  
Danger! All procedures described here re-  
quire a certain degree of skill, suitable tools  
and mechanical aptitude.After any adjust-  
ment perform a static check and take a test-  
ride on a quiet street, away from traffic. If  
you have any doubts please contact your lo-  
cal dealer.  
Unscrew the clamping screw to adjust the front boom.  
Caution! After you have unscrewed the  
clamping screws take them off and examine  
them for deformation. Lubricate threads and  
heads thoroughly.Then re-fit the screws. If  
they don't turn easily you will have to repla-  
ce the screws.

Adjusting the leg length  
In order to check the adjustments have anot-  
her person hold the bicycle while you are sit-  
ting on the recumbent.  
For riders with a short leg length the front  
boom has to be cut by a bicycle mechanic, so  
that it can be inserted to the maximum. It is  
important to trim the end of the tube neatly.  
Adjust the front boom in such a way that your The bare metal of the shortened tube end has

a plastic paper sleeve that accomplishes the re-  
quired clamping and protects the surface of  
the front boom.When the front boom has  
been completely removed take care not to da-  
mage the plastic paper adding while inserting it  
again.  
While you are pedaling, the ball of your foot  
should be positioned over the center of the  
pedal axle.  
It is important that your leg is not fully straigh-  
tened when the crank is in the foremost posi-  
tion. If the distance is too great it is difficult to  
overcome this dead point, pedaling becomes  
uncomfortable and there is too much strain on  
the sinews of your feet and legs. If the distance  
is too short you may suffer from knee pain or  
your legs bump on the handlebar.  
Caution! The minimum insertion depth of  
the front boom into the main frame is 10  
cm (4"). In no case may the end of the front  
boom be visible in the clamping slot when  
you look at the main frame from below, sin-  
ce it may result in a damage of the frame.  
Adjust the front boon so that your knee will not be fully straighte-  
ned when pedaling.  
The rear end of the front boon must never be visible in the clam-  
ping slot.

Adjust the front boom so that the bottom  
bracket axle is horizontal when you look at it  
from the front. For that purpose look beyond  
the bottom bracket shell at the rear wheel ax-  
le and align the front boom parallel to it.Align  
your eyes with the bottom bracket axle and  
not the front changer tube above.Then sit on  
your bicycle and check the position. (Hint:  
When you have the impression that the bot-  
tom bracket is turned alternately to the left  
and then to the right when cycling you will ha-  
ve found the correct middle position).  
Danger! After the chain has been shorte-  
ned it has to be closed with a special closing  
link or a chain riveting tool that expands the  
rivet while riveting (i.e. ROHLOFF- Revolver).  
A poorly joined chain may break and thus  
lead to a fall. Have adjustments of the chain  
length or the changing of the chain be done  
by your bicycle mechanic.  
Caution! Take care that the chain tubes ha-  
ve at least a clearance of 5 cm (2") to the  
rear derailleur and the front changer even  
under maximum tension of the chain and  
that the tubes stay tight in their fastenings.  
Shorten the tubes if necessary. If the end of  
the chain tube gets into the rotating drive  
train it could be locked-up and destroyed.  
The end of the rear chain tube has to be  
tightly secured with a cable tie behind the  
retention spring.  
Tighten the screw with a torque wrench (tigh-  
tening torque 14-16 Nm). On your first ride  
check whether there is sufficient clamping.  
Danger!If the screw is tightened too much  
or bent, the screw can break! If the clamping  
is insufficient the front boom can turn du-  
ring a ride which may cause your feet to slip  
from the pedals and lead to a dangerous fall.  
In order to move the bottom bracket tube  
your specialist dealer has to adjust the chain  
length. By default the Street Machine GT co-  
mes with a very long chain so that the adjust-  
ment range of the bicycle can be fully used wi-  
thout the need to lengthen the chain.  
After the first adjustment of the leg length that  
you have done together with your specialist  
dealer while handing over the bicycle, the  
chain has to be shortened so that the arm of  
the derailleur is not fully turned forward while  
shifting on the big chain ring in front and the  
big sprocket behind.The derailleur must still  
be able to compensate a length change of the  
chain of at least 4 cm. In order to choose the  
right chain length, please consult the manual of  
the derailleur manufacturer.  
Check that there is at least a 5 cm (2") clearance between the  
end of the chain tube and other parts of the drive train.

Adjusting the leg length  
After you have adjusted the front boom you  
should seal the gap in the clamping slot bet-  
ween the front boom and the main frame with  
wax or silicone in order to protect your frame  
from the penetration of water and dirt and  
hence damage through corrosion which may  
lead to a broken frame.  
We recommend you to slightly readjust the  
front boom every 3 months so that knee, mus-  
cless and ankles will be used differently, and  
you might find a more comfortable and more  
efficient riding position.  
A wrong adjustment may lead to pain in your  
knees and inefficient pedaling. In addition we  
recommend to ride with a high pedaling ca-  
dence, which means to pedal fast and with litt-  
le pressure. Pedaling with too much pressure  
may also lead to pain in the knees.You will find  
more information about this on page 26.

The selection of the right seat size and the

By the time you read this manual, you will alre-

the spine channel.  
In order to adjust the seat to your back length  
the seat comes in four different sizes:  
Approximate values are: Under a height of  
1,73 m (5' 8") we recommend seat size S, up  
to 1,83 m (6' 4") height seat size M, up to 1,93

Adjusting the seat position  
Adjusting the seat angle  
Adjusting the seat with mounted  
A big advantage of the Street Machine GT is  
that you can adjust the seat angle very quickly.  
For beginners or rides in the city you can  
choose an upright seat position for a better  
view, and for longer travels you can choose a  
flat position for better aerodynamics.  
Speedbag  
A mounted Speedbag impedes the access to  
the rear quick release for the adjustment of  
the seat angle.  
Therefore you should adjust your seat prior to  
mounting the Speedbag.You have to screw the  
Speedbag to the seat afterwards.  
The seat is fastened with two quick release le-  
vers on slotted aluminum seat mounts.You can  
adjust the angle by 10 degrees by simply ope-  
ning the two quick release levers. In the me-  
dium seat position the angle is about 35° from  
horizontal.  
It is possible to simplify the adjustment of the  
seat by replacing the knurled nut of the rear  
quick release by a big washer and a self-locking  
hex headed nut.This allows you to tighten or  
loosen the seat mounts with a tool you insert  
from behind.  
Because of the special cam shape of the two  
slotted holes, the seat effectively pivots around  
a central axis, approximately in the area of the  
lower lumbar vertebrae.This is the place whe-  
re you support the biggest part of your peda-  
ling force while riding, so this point determines  
the distance to the pedals.The advantage of  
this design is that you adjust the distance from  
the seat to the bottom bracket only once as  
described above, a change in the seat angle  
does not require an adjustment of the front  
boom.  
Caution! The two quick releases have to be  
closed firmly (tightening force 15-20 kg / 45  
lbs) to safely hold the seat.You are not allo-  
wed to open them while riding.After they  
have been closed the imprint "close" must  
be visible. If the quick releases are not tigh-  
tened appropriately the seat can move while  
riding and you may no more be able to  
handle your bicycle.

Adjusting the handlebars  
Tighten the screw with 14-16 Nm. Check the  
clamping by trying to turn the stem against the  
front wheel. Remount the rubber cap.  
Adjusting the handlebars  
As standard equipment the Street Machine GT  
comes with under seat steering.The position  
of the handlebars is under the legs.  
Alternatively, we offer above seat steering  
where the handlebars are above the legs.  
b)Adjusting the stem - A head stem  
Danger! Adjusting the stem also requires  
some work at the steering head bearing. In  
case of assembly errors the danger of acci-  
dents is increased. If you are in doubt have  
your bicycle mechanic adjust the stem.  
The handlebars are connected with the front  
fork through a stem.There are different stems  
for under seat steering in use:  
a) a vertically adjustable stem that is inserted  
in the steerer tube  
b) a stem that is clamped onto the steerer  
tube and at the same time fixes the  
steering head bearing (so called "A head  
stem")  
The A head stem is clamped onto the steerer  
tube with two screws.At the same time it fi-  
xes the steering head bearing.  
Adjusting the stem  
Starting at the fork, both stems have to point  
backwards to the seat.  
Danger! The hex-headed screw in the cap  
adjusts the play of the steering head bearing.  
This screw does not help to clamp the stem  
tightly to the steerer tube. It does not secu-  
re it against turning.Take care that both  
clamping screws on the side are tightened as  
prescribed after you have finished your  
works at the stem. Otherwise the stem may  
turn while riding and cause an accident.  
a) Adjusting the stem - vertically adjustable  
stem  
Remove the rubber plug and undo the hex-he-  
aded screw that lies below. If the stem still  
doesn't move then you can undo the clamping  
in the stem shaft with a gentle punch on the  
Allen key.  
Mount your bicycle, fix the front wheel with  
your feet and align the stem parallel to the  
front wheel.  
In case you only want to adjust the already  
mounted stem parallel to the front wheel you  
don't have to undo the screw on the cap.  
At the same time insert the stem so far in the  
steerer tube that the handlebars move freely  
under the seat even when the seat is in its  
most upright position.The minimum distance  
between seat and handlebars is 5 mm.Take ca-  
re that the minimum distance between the  
handlebar clamping at the stem and the frame  
of your bike is 5 mm.  
Mount your bicycle, fix the front wheel with  
your feet and align the stem parallel to the  
front wheel.  
Then tighten both clamping screws alternately  
with 8-10 Nm. Check the clamping by trying  
to turn the stem against the front wheel.  
Check the play of the steering head bearing,  
see below.

While riding you should allow your arms to  
rest in a relaxed position on the handlebars.  
Do not pull on the handlebars. If the handle-  
bars turn in the stem clamping during the ride  
stop immediately and tighten the clamping  
screw of the handlebars again. If the handle-  
bars turn in a stem that is not sufficiently  
clamped the handlebars or the stem might be  
damaged or deformed. In that case a secure  
clamping of the screw can no longer be guar-  
anteed, even with the correct tightening tor-  
que, and handlebars and stem have to be ex-  
changed.  
Adjusting the angle of the handle-  
bars  
By changing the angle of the handlebars you  
can adjust the position of the grip to the  
length of your upper body and your arms.  
Most riders are comfortable with a 45° angle  
so that the grip points diagonally to the front  
and up.The more upright the grip position the  
lesser is the maximum possible cramp of the  
handlebars, since it touches your legs earlier.  
In order to change the angle, undo the screw  
of the handlebars clamping by some turns.Turn  
the handlebars until they are in your favorite  
position. Check that the stem clamps the  
handlebars exactly in the middle.Tighten the  
clamping screw with 10-12 Nm. Check the  
correct clamping of the handlebars by moun-  
ting your bike and pulling the handlebars. In  
doing so they must not turn.  
Caution! After you have adjusted the hand-  
lebar position you also have to adjust the  
length of the brake cables and shifter cables.  
The cables have to run smoothly without  
any sharp turns and they may not be bent or  
stretched beyond their elastic limit when the  
handlebar is at maximum cramping.Also avo-  
id large arches that could be caught up in  
other parts.  
Please take care that the clamping area of the  
stem is thoroughly trimmed and does not have  
any sharp edges which may lead to a rupture  
of the handlebars.  
You can make smaller adjustments by moving  
the cables in their guides at the frame and the  
handlebar, so that there is enough room at all  
mobile parts. For this purpose you can move  
the cable for the front changer a little bit into  
or out of the frame. If this proves not to be  
sufficient you will have to have your specialist  
dealer shorten the cables or replace them by  
longer cables.  
Danger! Every time you undo the clamping  
connection you'll have to check the screw. It  
must not be bent, corroded or damaged. In  
addition to this you'll have to check the wel-  
ded-on thread nut of the clamping.The thre-  
ad must not be damaged and the screw  
must turn easily. In case of damage or defor-  
mation you have to exchange the clamping  
screw immediately.  
Handlebar grips  
The grips on the handlebar are susceptible to  
wear and tear. Have your grips replaced by  
your bike shop once they don't feel comforta-  
ble anymore.The grips always need to be atta-  
ched firmly to the handlebar.

Adjusting the suspension  
Purpose of the adjustment of the  
suspension  
Suspension and damping  
The suspension systems of the suspension fork  
and the rear swing arm are fitted with the ac-  
tual springs and dampers, which are mounted  
separately.  
Your Street Machine GT is fitted with a sus-  
pension fork for the front wheel and a rear  
swing arm for the suspension of the rear  
wheel.This system compensates small bumps  
on the road so that riding is comfortable and  
the strain on your bicycle is reduced.  
Often, the terms suspension and damping are  
used inappropriately in everyday language.  
The spring is the elastic element that com-  
presses and decompresses through the load,  
which occurs on bumpy roads.While decom-  
pressing the spring releases the same energy it  
has saved during compression.  
A well-adjusted suspension improves the trac-  
tion of your bicycle. Especially in bends this  
does not only allow a higher speed but it also  
increases your safety.  
In order to achieve maximum riding comfort,  
the suspension settings have to match your  
weight as well as the road condition.  
The Street Machine GT is fitted with coil  
springs of steel at the suspension fork and the  
rear fork swing arm. In addition to this the  
suspension fork contains springs made of mi-  
crocellular foam elastomers. (MCU).  
The goals of the adjustment are:  
G maximum use of the available suspension  
travel without the suspension frequently  
bottoming out  
G quick reaction of the suspension without  
obvious oscillation after having passed  
a bump  
G avoiding self inforcing oscillations, that means  
increasing oscillations of the suspension  
system due to pedaling influence, rhythmic  
body movements or permanent wavy  
underground  
The damper slows down the process of com-  
pression and decompression.That means that  
the bicycle after having passed a bump does  
not immediately "spring" back to the initial po-  
sition or even further than that.The damper  
converts spring energy into friction and finally  
into heat, and thus takes away energy from the  
suspension system.That way the damper pre-  
vents that the spring swings uncontrolled after  
an initial stimulation. In addition the damper  
helps to avoid self inforcing oscillations of the  
suspension that may be caused by reoccurring  
stimulation like pedaling forces within a crank  
revolution or the rhythmic up and down mo-  
vement of the legs.  
The hydraulic damping of the rear suspension  
is adjustable, in case you have mounted the op-  
tional suspension element DMM ST8ARC.

You should always set the damping as low as  
possible to give the bicycle the possibility to  
quickly react even to several bumps in a row.  
Adjusting to load  
The luggage carriers of the Street Machine GT  
are mounted to the suspended part of the fra-  
me.That way your luggage is also fully suspen-  
ded and it spares the material. Most notably,  
even under heavy load the suspension will  
compensate an uneven road much better and  
quicker compared to a design where the lugga-  
ge carrier would be mounted to the unsuspen-  
ded parts, e.g. the rear swing arm.  
You can ride the Street Machine GT with a  
considerably lower damping than for example  
a MTB: due to the relaxed and steady position  
of the body the recumbent does not experien-  
ce extreme variations in the load as it is  
known from dancing on the pedals while riding  
uphill on a mountain bike.  
Additional luggage changes the load of the  
wheels and their suspension.The suspensions  
are more compressed through the load.That  
way, there is less suspension travel for bumps  
while riding.Your suspension could seize up  
more often.  
In addition to this, varying pedaling forces have  
very little influence on the suspension of the  
bicycle due to the No Squat design of the sus-  
pension system of the Street Machine GT. So  
when you adjust the damping, always start with  
a low damping.  
The suspension of the front wheel is less affec-  
ted since luggage at the rear rack almost only  
puts weight on the rear wheel. Only in case of  
heavy luggage on the lowrider under the seat  
is there an influence on the front wheel.  
It is necessary to choose the correct spring  
stiffness to have a well operating suspension  
system.The spring stiffness is a measure for  
the compression of a spring at a certain load.  
It is either given in "N/mm" (Newton per  
Millimeters) or "lbs./inch" (Pounds per Inch).  
Sometimes you only find "lbs." printed on the  
springs.  
In order to compensate the variations in the  
load you can change the pre-load. For details  
see the following chapter.  
The suspension is designed in a way that the  
spring compresses considerably when you  
mount your bicycle.This is called negative sus-  
pension travel and it enables the bicycle to de-  
compress on bumpy roads. (Which is in fact a  
definitely positive feature.)You should choose  
a spring stiffness with which this negative sus-  
pension travel takes up around 30% of the  
overall suspension travel.This value usually  
provides a very comfortable ride on your fully  
suspended recumbent bike designed by HP  
VELOTECHNIK.  
Theoretically this can compensate for a load  
change of approx. 10 kg (23 lbs) at the rear  
wheel. In case of higher variations in the load  
you would have to exchange the spring for an-  
other spring with another spring stiffness. In  
practice you can often do without it: the  
1
Street Machine GT offers with 90 mm (3 /2") a  
lot of suspension travel for a touring bike.  
When you choose the spring stiffness so that  
the full 90 mm are at your disposal when your  
recumbent is under maximum load, you will  
have a somewhat smaller but still very comfor-  
table suspension travel when you ride without  
luggage.

Adjusting the suspension  
Adjusting the suspension fork  
The front fork of the Street Machine GT co-  
mes with telescopic suspension forks from  
BALLISTIC or MEKS.  
At your request different types of suspension  
forks can be mounted to your Street Machine  
GT, please notice the manuals of the suspen-  
sion fork manufacturer that are possibly enclo-  
sed.  
Turning knob for the pre-load of the suspension fork BALLISTIC  
XL-600All  
The suspension travel of the BALLISTIC fork is  
approx. 40 mm (1 /2"), of the MEKS fork ap-  
1
prox. 50 mm (2").  
The suspension fork should compress by 30%  
while mounting the bike, which corresponds to  
10-12 mm.  
You set this value by adjusting the pre-load of  
the spring, provided you chose the correct  
spring stiffness (page. 19).  
Every model has a turning knob on the fork  
legs that allows a simple adjustment of the  
pre-load.  
Turning knob for the pre-load of the suspension forks MEKS  
Carbon AC and MEKS Carbon All  
The suspension forks BALLISTIC XL-600All and  
MEKS Carbon All have springs in both fork legs,  
the suspension fork MEKS Carbon AC has  
springs only in the left fork leg since the other  
fork leg contains a hydraulic damping cartrid-  
ge.  
The knob must turn easily. If a knob does not  
turn any further you have reached the final po-  
sition. In that case turn the knob again in the  
other direction about half a turn.  
Do not turn the knob by force beyond the fi-  
nal position since this will damage the plastic  
thread inside.  
By turning the knobs clockwise you increase  
the pre-load, by turning them anti clockwise  
you decrease the pre-load.  
It is sufficient to set the pre-load in the two  
fork legs to approximately the same level. It is  
not necessary to match them exactly.

The suspension fork MEKS Carbon AC is fitted  
with a hydraulic damping unit. On the right  
fork leg is a turning knob to adjust the dam-  
ping.  
Choosing the spring stiffness of the  
suspension fork  
Your suspension fork comes by default with a  
standard spring that covers a wide range of lo-  
ad and riding styles.  
If the spring stiffness should not meet your re-  
quirements after adjusting the pre-load or if  
the suspension bottoms out too much, you  
can order a spring with another spring stiff-  
ness through your dealer and have it mounted  
there. For more information see page 41.  
It is not important to exactly follow the re-  
commended values for the negative travel, rat-  
her follow your feeling how the bicycle beha-  
ves during a ride, depending on the road situa-  
tion.  
Turning knob for the adjustment of the damping of the suspen-  
sion fork MEKS Carbon AC.  
You increase the damping by turning the knob  
clockwise.  
While riding you should only seldom feel the  
suspension bottoming out. However, in case  
this never occurs the spring might be to hard  
which means you don't use the total suspen-  
sion travel.  
We recommend you to start with the lowest  
possible damping. Only when the fork oscilla-  
tes more than once after you have gone over a  
bump should you increase the damping.  
When the fork works fine when passing a sin-  
gle bump but stiffens distinctly when passing  
several bumps that come quickly in a row, the  
damping is too high. However, when the fork  
"jumps" during the rebound movement the  
damping has to be increased.

Adjusting the suspension  
Adjusting the rear suspension ele-  
ment  
Danger! Take care that the rear wheel or  
mudguard never hits frame, rear rack or lug-  
gage box while the suspension is fully com-  
pressed.  
Danger! While adjusting the rear suspen-  
sion element never load the bicycle e.g.  
through resting on the seat or loading the  
rear rack when your hands or tools are clo-  
se to the suspension element. Otherwise  
your hands may get caught and squeezed  
when the suspension compresses.  
Therefore relax the spring completely by  
turning the spring retention disc on the  
thread of the spring element as far as it will  
go (before this, push the possibly existing sa-  
fety spring ring from its slot in the threaded  
section as far as it will go). Have a second  
person mount the bicycle and make the sus-  
pension bottom out by leaning on the seat  
or the rear rack.  
For the rear suspension of the Street Machine  
GT a steel spring is combined with a hydraulic  
damping unit in a spring element.The damping  
results from fluid friction of an oil flow  
through thin holes of a throttle valve in bet-  
ween two chambers inside the damper.A  
slightly noticeable sound that may occur from  
this oil flow is normal. Due to the fluid friction  
the spring element may heat up, therefore  
touch the spring element after a ride very ca-  
refully.  
If the distance between the wheel or mud-  
guard and the frame or rear rack is smaller  
than 1 cm you will have to mount an addi-  
tional spacer. In case you don't, the mud-  
guard may break suddenly or the rear wheel  
might be blocked which can lead to serious  
crashes.  
Danger! The suspension elements are filled  
with gas under high pressure. Never try to  
open the damper or to remove the screw at  
the gas tank. Inside the damper there are no  
user serviceable parts. In case of damage  
you will have to take the complete suspen-  
sion element to your dealer.  
The suspension travel is adjusted by adding clips to the piston  
rod of the spring element.

By adjusting the damping you can adjust the  
performance of the suspension precisely to  
your individual riding situation.A rough street  
with many harsh bumps that occur in a row or  
even cobblestones needs a low damping rate  
while a road with long stretched bumps that  
occur more regularly needs a stronger dam-  
ping to achieve a smooth road holding.  
Adjusting the damping (optional)  
Your Street Machine GT comes standard with  
a suspension element of which the springs can  
be exchanged and the pre-load adjusted.The  
damping in this suspension element is set to a  
fixed rate.  
When you add a lot of luggage you will need  
to adjust the spring stiffness; in that case an  
adjustment of the damping may even give you  
more riding comfort.  
Finally, the oil used in the damper becomes  
thicker and more viscous at lower temperatu-  
res, which can be compensated through a  
change in the damper setting.  
Suspension element DV-22 with fixed damping rate.  
Please note that you can seriously spoil the ri-  
ding comfort through a bad damper setting, es-  
pecially through unsystematic playing with the  
knobs that may result in much to high damper  
values. In the worst case the suspension ele-  
ment will neither compress nor decompress. If  
you are in doubt please consult your local dea-  
ler.  
As an upgrade option a rear suspension ele-  
ment with separately adjustable compression  
and rebound damping is available. In addition  
to this the suspension element has a bigger gas  
volume in the damper that leads to better sus-  
pension performance due to lower pressure  
and thus less stiction of the piston.  
Adjusting the compression damping  
In order to adjust the compression damping  
turn the knob on the downside of the suspen-  
sion element, when you look in driving direc-  
tion it is at the front of the suspension ele-  
ment.  
You get minimum damping when you turn the  
knob as far as it will go, when you look at the  
knob from the underside turn it clockwise.  
When you unscrew it the damping increases,  
the compression movement is slower, the  
damping gets harder.

Adjusting the suspension  
If you loosen the screw as far as it will go the  
suspension will be blocked completely; the re-  
ar wheel will have no more suspension.

sen it again by half a turn.Thus, the suspension  
compresses quickly when a bump occurs.  
In order to adjust the damping during decom-  
pression, turn the adjustment knob on top of  
the rear end of the suspension element.You  
will get the lowest damping through turning  
the knob clockwise as far as it will go when  
you look at it from above.When you unscrew  
it anti-clockwise the damping increases. If you

Also, when you go uphill you don't need to

press after a shock anymore.  
The writing on the knobs can be sometimes  
confusing, it is easier to remember the follo-  
wing:  
Adjusting the rebound damping  
The rebound damping prevents an eventual  
"jumping" of the rear wheel and provides a  
good traction. By improving the road surface  
contact the suspension of the Street Machine  
GT also increases your riding safety.  
The farther out the knob the more damping you  
get. Unscrew the knob as far out as it will go me-  
ans that nothing moves anymore.  
A higher damping value prolongs the time until  
the decompression movement is finished. Only  
then can the suspension compensate the next  
shock with the full suspension travel.  
Therefore, when you ride on very bumpy  
streets with shocks that occur fast in a row  
you might want to use a lower damping value.

Adjusting the pre-load of the sus-  
pension  
The pre-load determines how far the suspen-  
sion compresses when you are sitting on the  
bicycle while standing still.  
For the rear wheel the same guidelines as for  
the suspension fork are valid: for maximum ri-  
ding comfort the suspension should compress  
by about 30% of the total suspension travel  
while you mount the bicycle in driving posi-  
tion.  
Turn the knurled ring to adjust the pre-load.  
For that purpose measure (similar to the me-  
thod described for the suspension fork) the  
distance between the two suspension element  
bolts or between rear rack and rear wheel  
while the bike is unloaded as well as while sit-  
ting on the bicycle in riding position.Also take  
into account possible luggage. Find out the to-  
tal suspension travel possible for your bicycle  
with the method described above, depending  
on the mounted add-on-parts and the spacers.  
The static compression should amount to ab-  
out one third of the overall suspension travel.  
Danger! The adjustment ring has always to  
be screwed so far towards the spring that  
the spring has no play when unloaded.  
Otherwise the adjustment ring could come  
loose through shocks while riding so that  
the slotted rear spring retention disc comes  
off. In that case the suspension element may  
be damaged or the rear wheel could hit the  
frame or rear rack, which may lead to se-  
rious falls.Always have an initial pre-load of  
at least half a turn on the spring.  
You can affect this negative suspension travel  
depending on how much you weigh and how  
much you load your bike either by adjusting  
the suspension pre-load for fine tuning or by  
replacing the spring with a spring with a diffe-  
rent stiffness in the rough tuning.  
The adjustment ring should be turned no mo-  
re than five turns (measured from the relaxed  
position) towards the spring. If the suspension  
compresses still too far even after six turns,  
the spring is too soft and has to be replaced  
by a harder spring.A too big pre-load of a too  
soft spring does not take advantage of the full  
comfort potential.  
In order to adjust the suspension pre-load  
turn the knobby adjustment ring on the threa-  
ded part of the suspension element by hand.  
Turning the adjustment ring clockwise (looking  
at it from behind) reduces the preload, turning  
it anti-clockwise you screw the adjustment  
ring towards the spring and increase the sus-  
pension pre-load. It is helpful to turn the  
spring together with the adjustment ring.  
You will find more information on changing  
springs in this manual under "Maintenance and  
Care", page 45.

Learning the new riding technique  
Your new bicycle has been assembled by your  
dealer and adjusted together with you as des-  
cribed on the previous pages under "Adjusting  
your new bicycle". Before you mount your bike  
and enjoy your first ride please make yourself  
familiar with the instructions on the riding  
technique and the handling.  
Look ahead in the direction where you want  
to ride, not on the handlebar, at your feet or  
the front wheel.  
In order to stop brake carefully with both bra-  
kes until the bicycle has come to a complete  
stop. Only then do put a foot on the ground  
and keep the balance.  
Learning the new riding technique  
To ride this recumbent you will have to make  
yourself acquainted with the different riding  
position. Make sure that you and all other fu-  
ture users of this bicycle will have read this  
manual carefully prior to the first ride. If you  
are in doubt please consult your local dealer.  
Danger! Never touch the ground with your  
feet while the bicycle is still moving.The feet  
could be caught on the ground and be pulled  
backwards which could lead to a serious in-  
jury.  
Before the first ride the users of this recum-  
bent have to practice and make themselves fa-  
miliar with the different handling.We recom-  
mend to practice on a quiet road away from  
traffic. Before you ride the bicycle in traffic you  
must master the handling completely.  
Danger! With a compact recumbent like  
the Street Machine GT it is possible that a  
foot of the rider contacts the front wheel  
when riding sharp corners with a pedal in a  
low position.You will have to avoid this situ-  
ation at all times since in extreme situations  
it may lead to a fall and injuries.  
Go to a road where you can ride straight ahe-  
ad without being hindered. Hold your bike at  
the handlebars and pull a break.Then mount  
your bicycle and lean back. Leave one foot on  
the ground and put one on the pedal.  
To control the bicycle you will therefore ha-  
ve to apply the following cornering techni-  
que: when you ride a curve stretch the leg  
on the inside of the curve, stop pedaling, on-  
ly then start steering into the curve. Only  
when you ride straight ahead again should  
you resume pedaling.  
Therefore rotate the crank in the top position  
so that you can pedal immediately with power.  
Try to keep your balance in that position.  
Assure yourself that you can stop whenever  
you want to and hold the bicycle with one  
foot on the ground.When you feel safe put  
pressure on the pedal, loosen the brake, pedal  
with a lot of force and immediately put your  
second foot on the other pedal.  
Danger! Please note that due to your low  
seat height other road users may notice you  
very late. Ride anticipatory with this in mind.  
This is especially important while riding in  
darkness.You yourself have a much better  
view than others perceive you. Ride defensi-  
vely.We recommend you to mount a well vi-  
sible and reflecting flag to the bicycle while  
using it in traffic. Please ask your dealer for  
more information.  
Do not care on which side of pedal you are  
currently pedaling in the beginning. Hold the  
handlebar loose but steady and accelerate with  
a few pedal strokes.Your bicycle needs speed  
to stabilize.

low 60 revolutions when going uphill. If neces-  
sary have your specialist dealer adjust the gear  
range to your riding style and the terrain you  
usually ride.  
Slowly increase the strain  
We recommend you to perform only short ri-  
des without much power during the first  
weeks.  
Always use a low gear and ride with a high pe-  
daling frequency. Only after having acquired so-  
me training do increase the strain slowly.  
You will find many tips on proper training for  
cyclists in miscellaneous books and magazines  
for cyclists.  
When you ride on a recumbent you use other  
muscles than on a conventional bicycle, and  
they have to be trained first.The very high po-  
sition of the bottom bracket requires your  
muscles and blood transport system to slowly  
familiarize with the new position.  
In case of persistent problems please consult  
your doctor.  
Do not ride freehand  
In case of an overload the blood circulation in  
your legs may be affected which shows in loss  
of power, a prickling in the toes, falling asleep  
of the legs or cramps.When you have a sporty  
way of riding it can take up to 6 months until  
you have become accustomed to your new re-  
cumbent.  
Danger! In order to ride safely you have to  
keep both hands at the handlebar. Even  
when signaling keep at least one hand at the  
handlebar. Otherwise, unforeseen bumps in  
the road or oscillations of the steering may  
lead to a serious fall.

way of riding, Quick release levers  
In the second half of the lever's movement the  
force on the leer should increase considerably,  
corresponding in the end to 15-20 kg (46 lbs).  
Caution! Always carry your bicycle over  
stairs and curbstones. Do not ride through  
big road holes. Especially when road holes  
are filled with water it is very difficult to  
guess how deep they really are. In case you  
hit such an obstacle frame and fork may be  
damaged which can result in a serious fall.At  
first, the damage may be unnoticed. Please  
check your bicycle immediately for deforma-  
tions and cracks. If you are in doubt please  
consult your local dealer.  
In its final position the lever should lie parallel  
with the bicycle and should not stick out to  
one side.  
Check the security of the lever by attempting  
to twist the lever. If the lever can be made to  
pivot around in a circle the clamping is too  
loose.You must re-open the quick release,  
hold the lever and increase the clamping ten-  
sion. Do this by screwing the adjustment nut  
on the other side by half a turn. Close the le-  
ver and check the clamping anew.  
Quick release levers  
Quick release levers hold wheels and seat in  
position.  
Finally, check that the part being secured is  
firmly fixed: Lift each wheel several inches off  
the ground and give it a slap onto the tire  
from above.A properly fixed wheel will remain  
secure in the frame's dropouts.  
Danger! An incompletely or improperly  
closed quick release can result in parts co-  
ming loose, and hence in a crash, possibly re-  
sulting in serious injury.  
The dropouts of the fork of your Street  
Machine Gt are designed as safety dropouts.  
Therefore you always have to loosen the clam-  
ping nut of the quick release when you take off  
the front wheel.When you reassemble it do  
not forget to tighten the nut again!  
A quick release lever consists of two basic  
parts: the lever on one side provides the clam-  
ping force.With the adjusting nut on the other  
side you adjust the clamping tension on the  
screw thread.  
To open the quick release, move the lever  
away from the frame. In doing so the inscrip-  
tion "open" should be visible on the lever.  
Parts that are fastened with a quick release  
open easily.Thus, they are more susceptible to  
theft.Therefore, always secure the wheels with  
a lock when you park your bicycle. It is also  
possible to exchange the quick releases with  
special security screws (e.g. from PITLOCK or  
KRYPTONITE) that can only be opened with a  
special tool. For this please consult your local  
specialist dealer.  
To close the quick release, move the lever with  
power in the other direction so that the word  
"close" is visible on the outward side of the le-  
ver.At the start of the lever's motion, for, say,  
half of its movement, the lever should move  
very easily, without any clamping action.

Brakes  
Brakes  
Danger! Please note that the braking  
distance is much longer when it is wet or  
when the bike is heavily loaded.When riding  
on wet, sandy, icy or slippery roads you have  
to use the front brake very carefully to avoid  
that your front wheel slips. If it does so you  
will no longer be able to handle your bike,  
which might lead to a serious fall.  
The Street Machine GT is equipped with a po-  
werful high-quality brake system.You may  
choose between rim brakes and disc brakes.  
Please do read the separate manual that co-  
mes with your bike for details.  
Make yourself familiar with the braking system.  
Remember which lever pulls the front brake  
and which the rear brake.  
Do not brake in a bend, always brake before a  
bend. Braking increases the risk of slipping.  
Especially when it is wet the rear wheel imme-  
diately slides out of the bend while braking  
and this can result in a serious fall!  
If the arrangement of the levers does not cor-  
respond to what you are used to, please have a  
two-wheeler mechanic change it. Please con-  
tact your local specialist dealer whether there  
exists any legal requirement for the arrange-  
ment of the brake levers in your country.  
Danger! In case you get into a situation like  
that during an emergency stop you have to  
let go of the brakes immediately, balance  
your bicycle and brake again. If you are not  
familiar with the brakes we recommend you  
to train at first at low speed and with little  
braking effect until you find the correct dose  
for an emergency stop.  
Note that the front brake is the most effective  
brake on the Street Machine GT.With the  
front brake, you achieve a much higher braking  
effect than with the rear brake.The rear wheel  
has a tendency to lock up and slip on the pa-  
vement even under low braking forces.The  
braking effect of modern brake systems can be  
more powerful than what you have been used  
to until now. Do brake carefully.When you  
brake too much with the front brake the rear  
wheel may lift off the street and the bike may  
tumble over.  
If you should hear any unusual sounds while  
braking the braking pads might be worn. Do  
not use your bike any further until you have  
checked the braking pads according to the ma-  
nual of the brake manufacturer or ask your lo-  
cal dealer.

Your new brake system needs a break-in peri-  
od to achieve maximum brake power.This pe-  
riod lasts for about 30-40 stops from about 30  
km/h, which should be done in a safe area wi-  
thout traffic.  
Danger! Always make sure that the disc and  
brake pads are free of oil and grease. If these  
parts are dirty please do not use your bicy-  
cle any more.You can clean oily rims or  
discs with alcohol or a special spray. Oily  
brake pads with oil on them have to be re-  
placed. If you are in doubt, please have your  
specialist dealer maintain your brake system.  
Danger! Disc brakes can overheat on long  
down hill rides, fade and fail! On down hill  
rides, do not brake constantly, but in several  
intervall with higher pressure. If you notice  
that the brake power starts to fade, do stop  
immediately and let your brakes cool down.  
Information for hydraulic rim brakes or disc  
brakes  
Check before every ride:  
G that the brake system does not have any  
damages or leaks by activating the lever,  
holding it and checking the hose connections  
for possible leaks.  
Danger! Never touch neither the brake  
disc nor the brake caliper after long braking  
as this may cause serious injury (risk of  
burns).  
G that the brake lever pressure is ok by pulling  
the lever and ensuring that full braking  
performance is achieved before the lever  
touches the handlebar. If this is not the case,  
pull the lever several times (pump) until it  
feels firm.

Gear system  
You may only change the gears while you keep  
pedaling, smoothly and without applying great  
force, all the time that the chain is moving bet-  
ween the sprockets. Due to the long cables  
that expand under pressure and the housing  
that compresses under pressure it may be hel-  
pful for changing gears quickly to turn the bar  
end shifter a little bit farther than necessary to  
select a gear and turn it back to the indexed  
position once the chain has properly shifted  
("overshift").  
Gear system  
With the gear system you can adjust the peda-  
ling frequency, i.e. means the number of revolu-  
tions of the crank per minute, to the terrain  
and the desired speed.  
Your pedaling frequency should stay between  
80-100 revolutions per minute and not fall be-  
low 60 while going uphill. If necessary consult  
your local dealer and have him retrofit the ge-  
ar range to your style of riding.  
When the chain length has been propperly ad-  
justed you can choose every combination of  
front chain rings and rear sprockets to shift  
gears. However, it is useful to ride the lowest  
gears with the smallest chain ring (the biggest  
rear sprocket), the middle gears with the  
middle chain ring and the highest (fastest) ge-  
ars with the biggest chain ring.  
Your Street Machine GT comes standard with  
a 27-gear derailleur gear or with a 14-speed  
internal hub gear system.The following section  
refers to the derailleur gear system only.  
Please refer to the manual of the gear manu-  
facturer.  
You operate the gear changer with the bar  
end shifters on the handlebars.  
The setup of the chain rings and sprocket le-  
ads to an overlap of some gears.This means  
that different combinations of chain rings and  
sprockets can result in the same gear. It would  
be possible to arrange a gear system so that  
double gears do not occur but this requires a  
lot of concentration when you shift gears whi-  
le riding, since you will always have to change  
the rear sprockets as well as the front chain  
rings. If you would like to change the setup of  
your gears please consult your local dealer.  
The right lever for the rear derailleur has an  
index derailleur system that positions the  
chain always on the chosen sprocket, so that  
you don't have to "search" for the gears.  
It is not possible to index the left lever so that  
you have to adjust the front derailleur while  
shifting by slightly moving the shifter to stop  
the front derailleur from dragging against the  
chain while pedaling.  
Riding a recumbent requires foresighted gear  
shifting. Before stopping you should timely  
change in a low gear to make it easy to start  
off again, without having to pedal heavily and  
struggling with your balance.  
Danger! Do practice shifting gears on a  
traffic-free street. In the course of this make  
yourself familiar with the functioning of the  
bar end shifters. Doing this in traffic could  
distract your attention from possible dan-  
gers.

Light system  
Light system  
If you want to ride your bike on public streets,  
it must be equipped with a legal light system.  
Do not only use your lights in the dark but al-  
so in the twilight of dusk and dawn. Due to  
laws and regulations the brightness of bicycle  
lights may be considerably lower than that of  
other vehicles.Therefore always keep in mind  
that other road-users may only see you very  
late or not at all.  
red button  
pressure  
adjuster  
You switch on the tire dynamo by pressing the red button.To  
switch off the dynamo move it away from the wheel.  
For the Street Machine Gt, HPVELOTECHNIK of-  
fers two different dynamo light systems: one  
with a tire dynamo and the other with a hub  
generator.  
Danger! Do not try to operate the dynamo  
lever while riding, your hands could be  
caught in the wheel and be injured! To turn  
the light system on or off stop riding, dis-  
mount your bicycle and only then do turn  
the dynamo lever.Turn the lever carefully wi-  
thout applying force else you might bend the  
lever and damage the plastic parts of the dy-  
namo.  
Both light systems come with a strong halogen  
headlamp and a LED rear light.The LEDs in  
the rear light last considerably longer (approx.  
100.000 working hours) than a light bulb. For  
your safety the light system has a standlight  
system at the front and at the rear light, which  
makes the LEDs shine on approximately 10  
minutes after you have stopped riding.The  
electronic system is maintenance free. Because  
of the capacitors used you don't have to wor-  
ry about batteries.  
You can adjust the pressure of the dynamo  
against the wheel with the turning knob at the  
side.The pressure is right when the dynamo  
wheel just does not slip at the wheel, if the  
light flickers, the pressure is too low and you  
have to increase it.The position of the dynamo  
should be so that the extension of the dynamo  
axle points through the center of the wheel.  
Take care that the dynamo is mounted safely  
and does not turn.Worn dynamo wheels can  
be exchanged. Please ask your specialist dealer.  
The light bulb in your front light can be des-  
troyed by wear.Always carry a spare bulb with  
you.Take care not to touch the bulb with your  
bare fingers, always use a soft cloth.Touching  
the glass of the light bulb with bare fingers will  
reduce the lifetime of the light bulb.  
Tire dynamo  
You turn on the light system with the tire dy-  
namo at the rear wheel by unlocking the swi-  
veling dynamo. For this purpose you press the  
red button at the dynamo until it moves to-  
wards the rear wheel.To turn the light off, you  
turn the dynamo by hand back to its initial po-  
sition.

Light system, Prop stand  
Hub generator  
Prop stand  
The light system with a hub generator is swit-  
ched on electrically. For this purpose you will  
find a switch on the back of the rear light with  
three labeled switch positions.With the switch  
you can turn the lighting system ON, OFF or  
set it to SENSOR. In the SENSOR position a  
twilight sensor in the lamp turns the lighting  
system on and off automatically depending on  
the brightness of the environment.  
Danger! Before every ride check whether  
the prop stand is lifted up to its riding posi-  
tion.With a recumbent prop stands are of-  
ten forgotten. In the first left turn the prop  
stand can touch the ground and cause a fall!  
After a fall you will have to check the prop  
stand and the area where it is mounted for  
damage and deformation.  
For the Street Machine GT you can use a rear  
prop stand at the frame or a prop stand that  
comes with the optional lowrider.  
You get maximum effect with the prop stand  
at the lowrider. It supports the bicycle in the  
middle of the bike between the wheels.  
In case no lowrider is mounted to your bicycle  
you can support it with a special rear prop  
stand.  
You switch on the hub generator light system with the integrated  
switch at the front light.  
The rear prop stand is mounted at the axle,  
put on the quick release axle and supports it-  
self at the frame.There has to be a washer  
between prop stand and drop out, otherwise  
the prop stand is not mounted safely due to  
the special shape of the drop out.  
The SON hub generator is highly efficient and  
works silently.When the dynamo is turned off  
it has a very low turning resistance.Although  
you can feel the single poles of the used per-  
manent magnets very distinctly when turning it  
by hand the real rolling resistance is minute.  
(The loss is at 15 km/h under 1 Watt).  
From spring 2002 on the rear swing arm co-  
mes with a welded plate for the PLETSCHER  
prop stand.The screws have to be free of gre-  
ase, mounted with Loctite and tightened with  
8-10 Nm.

Maintenance and care  
Brakes  
Your Street Machine GT is fitted with the la-  
test bicycle technology that does not require  
much maintenance.  
The brake pads suffer from wear due to fric-  
tion and have to be exchanged then.  
The brake pads of your rim brakes are worn  
when you can pull the lever further and furt-  
However, you will have to maintain your bicy-  
cle regularly, as it is with other vehicles too.At her to the handlebar before the pads touch  
least once a year the bicycle has to be taken  
to a bicycle mechanic for an overall service.  
Only this way a long lasting and safe function  
of all parts of your bicycle can be guaranteed.  
It maintains the value of your bicycle as well as  
the fun and the safety while riding for many  
years.  
the rim.When they are so worn that you can't  
see the cross grooves of the pad anymore you  
will have your bicycle mechanic exchange the  
brake pads.  
Also the rim walls suffer from wear.When the  
rims are too worn the tire pressure can tear  
up the rim and damage the wheel - danger!  
Please have your bicycle mechanic check your  
rims at the latest after the second brake pad  
change and exchange them if necessary.  
Read in this chapter how you can carry out  
smaller maintenance and care works between  
the services.  
For a quick overview of the works to be done V-brakes with cables  
take a look at the warranty pass on page 58.  
To balance the wear of the brake pads you can  
tighten the cable with the knurled nut where  
the cable goes into the brake lever. First loo-  
sen the locknut, then undo the screw so far  
that the wheel turns, barely not touching the  
pads, hold the screw and tighten the locknut  
again towards the brake lever.  
Caution! The maintenance works of this re-  
cumbent partly require special tools and  
skills. Do only work within your limits and,  
in the interests of your own safety, do not  
go beyond. Should you be uncertain at any  
point, get in contact with your local dealer.  
Caution! Damaged cables where single  
wires stick out have to be exchanged im-  
mediately. Otherwise your brake system  
may fail - danger! Please take care that the  
cable ends are always protected with a cap.  
Wear andTear  
Like every other vehicle the bicycle has parts  
that suffer from wear and tear.The life span of  
these parts depends on how often and how  
they are used, as well as how they are cared  
for. Please note that the wear and tear of cer-  
tain parts of the bicycle is perfectly normal  
and not a reason for complaint.This manual  
contains information about the most frequent  
wearing parts.

Brakes  
Hydraulic brakes  
Hydraulic disc brakes  
MAGURA hydraulic brakes use low viscosity mi-  
neral oil that, contrary to DOT brake liquid  
used in cars, does not absorb water.Thus, you  
don't have to change the oil. Please read the  
MAGURA manual that comes with the bike.You  
will find more detailed maintenance instruc-  
tions in the manual "Workshop" that is availa-  
ble for download from MAGURA at www.magu-  
ra.com. In case of a damaged hose or any lea-  
kage of oil always consult a qualified technician  
in a bike shop.  
MAGURA Clara disc brakes model 2001 or later  
feature a fully automatic pad wear adjustment.  
Brake pads are subject to wear, therefore re-  
gularly check the thickness of your brake pads  
and replace them, if necessary.  
Caution! Never activate the lever blade wi-  
thout the brake pads in place and with the  
wheel dismounted.When you transport the  
bicycle without wheels always use the trans-  
port clips delivered with your bike or put a  
piece of cardboard in the brake caliper to  
replace the disc. Carefully separate brake  
pads that have moved together with a  
screwdriver.  
Danger! All maintenance work on the hy-  
draulic system of your brakes may only be  
carried out by a qualified technician. In case  
these works are carried out without the re-  
quired knowledge and skills the brake  
system might fail which can lead to a serious  
crash.  
The brake caliper is bolted to the frame with  
M6 screws, tightening torque is 6 Nm.To  
achieve the perfect alignment of brake caliper  
and rotor, tiny washers of 0,2 mm thickness  
can be added between brake caliper and frame  
fittings.  
Hydraulic rim brakes  
To balance the wear of the brake pads there is  
a turning knob at the brake lever.Turn this  
knob anti clockwise to move the pads closer  
to the rim.As soon as the knob doesn't turn  
anymore the brake pads have to be exchanged.  
Before you change the pads turn the knob  
clockwise as far as it will go, back to the initial  
position.

Gear system  
Gear System  
Danger! If the bike falls over, the derailleur  
or its mounting can be bent so that the mo-  
vement of the derailleur changes. Check the  
movement and have it readjusted by your bi-  
cycle mechanic, if necessary.  
Please read the manual of the gear system ma-  
nufacturer carefully when you want to work  
on it.  
Your dealer will have carefully adjusted your  
derailleur gearing system before handing over  
the bike. But during the first 100 kilometers of  
riding the gear cables can stretch, making the  
gear indexing imprecise.The chain then climbs  
only hesitantly onto the next sprocket.  
All moving parts of the gear system are affec-  
ted by wear. Cleaning and lubricating these  
parts frequently can prolong the life of these  
parts, however they will have to be replaced  
once worn out.  
Adjusting the gear indexing for the rear  
derailleur  
Adjust the barrel adjuster where the gear ca-  
ble goes into the rear derailleur. Do it in small  
steps of half a turn.  
The cables have to be checked, cleaned and  
serviced regularly. Expect more wear and cor-  
rosion when the bike is often parked outside  
in bad weather conditions.  
Check after each adjustment whether the  
chain moves smoothly up to the next larger  
sprocket.To do this, either turn the cranks by  
hand or ride the bike.  
Caution! Damaged cables that show for  
example single wires have to be changed  
immediately. Otherwise they may damage  
your gear system.Take care that the ends  
of the cables are protected with fitting  
caps.  
When the chain climbs up easily, you need to  
check that it still goes down easily onto the  
smallest sprocket. If necessary turn the barrel  
adjuster a little more and then try shifting ge-  
ars again.  
Danger! If the chain shifts over the smallest  
or the biggest sprocket you have to readjust  
the end-limit adjusters of the rear or the  
front derailleur. Incorrect adjustment can le-  
ad to the chain coming off, getting stuck or  
damaging the spokes, which may result in se-  
rious falls.The adjustment of the end-limit  
adjusters is a job for the professional cycle  
mechanic.

Chain  
Chain  
Danger! Take care not to pour any oil on  
the rims, brake discs or the tires.The brake  
system could fail or the tires could slip away  
suddenly.The oil affects the rubber of your  
tires and could damage them.While lubrica-  
ting cover the surrounding area with an old  
newspaper.  
The chain is a wearing part that has to be lu-  
bricated regularly and to be changed at signs  
of excessive wear and tear.  
Lubricating the chain  
Diligent lubrication is important.The chain of  
your Street Machine GT is approximately 2.5  
times longer than a standard bicycle chain (ap-  
prox. 3.8 m). But it also lasts longer since a  
chain only wears while bending at the sprok-  
kets and the chain rings.  
An effective protection against corrosion is  
critical for a long chain life. Some minutes after  
you have oiled the chain rub it with a cloth to  
remove superfluous oil from the outer surface.  
Wax the chain thoroughly with a wax spray.  
The wax keeps off water, protects from corro-  
sion and makes dirt fall off easily.  
Use a good chain oil that won't leave a sticky  
film on the chain.The chain oil may not con-  
tain any aggressive chemical substances that  
might affect the surface of the chain tube.  
If the chain has become wet after riding in the  
rain you should put your bicycle in a dry and  
heated room, and every day you should turn  
the crank and so move the chain until it is dry  
again. Otherwise it is difficult for the moisture  
in the tubes to evaporate which may lead to  
corrosion at the chain.  
Specialist stores sell biodegradable lubricants.  
HPVELOTECHNIK solely recommends  
PROFIDRYLUBE.This lubricant is purely based on  
PTFE (Teflon) that keeps the chain clean and  
dry.This way dirt simply falls off and the tubes  
(also made of Teflon) always stay clean.Your  
dealer can obtain it from HPVELOTECHNIK.  
It is important that you clean the chain with an  
oily cloth before lubricating. Otherwise the  
fresh oil washes the dirt that clings to the  
chain into the gaps and the bushings where the  
dirt causes heavy wear.  
Do not use any solvents to clean the chain!  
The solvent washes the oil off the bearing  
parts, stays there and dilutes the fresh oil so  
that a sufficient lubrication is not guaranteed. If  
you have treated the chain with a solvent you  
will have to heat it up with a hot air torch or  
boil it in chain grease.

front and the big rear sprocket.The derailleur  
must be able to compensate a tightening of  
the chain by 4 cm. Please see also the manual  
of the derailleur manufacturer on the choice  
of the correct chain length.  
Check the chain regularly for lengthening. For  
this purpose try to remove the chain from the  
chain ring.The chain may come off to a maxi-  
mum of 5 mm. For a more precise reading you  
can buy a chain measurement gauge in your bi-  
ke shop that you simply put into the chain.  
Caution! The chain has to be closed with a  
special joining link or a chain riveting tool  
that expands the ends of the rivet while ri-  
veting (ROHLOFF revolver).A poorly joined  
chain may break, you can come off the pe-  
dals and fall. If you are in doubt please have  
adjustments of the chain length or the chan-  
ging of the chain be done by your bicycle  
mechanic.  
Only use chains that are suitable for the gear  
system of your bike. Otherwise a precise gear  
shifting is not guaranteed any more. Please  
consult your dealer on this topic. He will also  
assist you in checking your sprockets and chain  
rings.A new chain does not fit a worn sprok-  
ket or chain ring.We recommend chains from  
SRAM with smoothly rounded edges.They also  
shift gears very well.  
See that the joining link is not bigger in size  
than the other chain links to avoid irregular  
chain sounds.We recommend the joining links  
by SRAM (power links). Every time you change  
the chain you also have to mount a new po-  
wer link.  
Caution! When you change the chain take  
care that the new chain does not show any  
sharp edges or burrs.Very thin racing chains  
are also not suitable since they wear the  
chain tubes and the chain roller much faster.  
HPVELOTECHNIK delivers spare chains by the  
meter via your dealer. For this purpose please  
indicate the exact length of your chain or or-  
der it a little bit longer if you want to be sure  
it fits.You will need approx. 3,8 m of chain.

ChainTubes  
Expanding the tube ends  
Chain tubes  
The ends of the tubes are expanded like a  
trumpet so that the chain can enter smoothly  
without friction and without making noises.  
The chain protection tubes consist of Teflon, a  
long lasting plastic, that features very low fric-  
tion, slow wear and good noise damping.The  
tubes protect your clothes against the chain oil  
as well as the chain against dirt from the road.  
When the ends are worn out you can renew  
them through expansion. Remove the chain by  
opening the power link or open it with a spe-  
cial chain riveting tool. Cut the worn part of  
the tube exactly perpendicular with a sharp  
knife.  
The upper tubes are fastened with an inter-  
changeable retention spring, the lower tube  
runs through an adjustable clip.  
The tubes are worn by the chain and have to  
be cut at the ends and expanded again (or ex-  
changed) after 3.000-5.000 km approximately,  
depending on how many kilometers have been  
ridden, on the chain type and the overall riding  
condition.You can extend this maintenance  
interval by turning the tubes by a quarter turn  
from time to time so that they do not keep  
wearing out in the same place.  
Heat the last 5-10 mm at the end of the tube  
with a gas burner or a candle and turn it per-  
manently until the color of the utmost edge  
turns from a dull black to a shiny black. Now  
you expand the end with a proper tool, e.g.  
the rounded grip of a screwdriver. Quench the  
expanded end immediately with cold water.  
Take care that the tubes don't catch fire since  
burning Teflon develops toxic vapors.At any  
rate, work in a place with sufficient ventilation.  
The intensity of the wear depends mainly on  
the chain type. Please see also the instructions  
on "Chain" on page 36.  
If the tube is too short after you have cut it so  
that there is not enough protection anymore it  
has to be replaced.You can buy spare tubes  
either as uncut tubes or already cut into the  
correct length, complete with retention spring  
from your specialist dealer.  
In order to perform any work at the chain tu-  
bes you'll have to open the chain and finally  
close it again. Please see the instructions on  
"Chain" on page 36.  
Caution! Take care that the chain tubes  
keep at least a 5 cm distance to the rear and  
front derailleur when the chain is stretched  
to the maximum, and that the tubes are well  
fastened. If necessary you will have to shor-  
ten the tubes. If the end of a chain tube gets  
into the rotating drive train it can be blok-  
ked and the chain tubes may be destroyed.

Changing the tubes  
Changing the lower chain tube  
In order to exchange single parts in the upper  
chain tubes cut the old tube at the retention  
spring at the chain roller and pull the remai-  
ning part off the spring. Now move the  
smooth part of the new tube through the  
spring and expand the tube end as described  
above.  
Open the retention clips. On the bottom side  
of the clip there is a lid that is put over a  
hook.You can lift up the lid with a screwdriver  
and expand the clip. Change the lower chain  
tube and close the clips by fastening the lids  
over the hooks.  
Caution! The rear end of the upper chain  
tube has to be secured against moving with  
a cable tie that is wrapped around the tube  
near the retention spring.Without the cable  
tie the tube may be dragged forward into  
the turning chain guide and thus be damaged  
by the chain.  
Changing the complete upper chain pro-  
tection or the retention spring  
Disassemble the chain roller. For this purpose  
hold the nut on the left side of the frame with  
a ring spanner SW 13 and undo the screw in  
the chain roller with an Allen key SW 8.  
Remember the exact position of the spacers.  
Take the bolt off the frame together with the  
chain roller. Between frame and chain roller is  
a spacer that is encased in a transparent  
plastic tube.  
Take the retention spring off this spacer and  
put on the new retention spring.Turn the  
spring so that the retention springs run under  
the spacer to the tubes and the wires lie bet-  
ween frame and chain tube; that way the spi-  
rals look outwards.  
Lubricate the shaft of the retaining bolt. Push  
the bolt through the chain roller, the washer,  
the chain retention hook and the spacer with  
the retention spring into the frame. Put on the  
washer on the left side, secure the thread with  
Loctite and tighten the nut with 14-16 Nm.

Chain roller  
Chain roller  
Dismounting the chain roller  
The chain roller guides the chain below the se-  
at to the rear wheel and is an essential part of  
the HPVELOTECHNIK No Squat design. It ensu-  
res that no pedaling influences get into the  
suspension.  
Hold the nut on the left side of the frame with  
a ring spanner SW 13 and undo the screw in  
the chain roller with an Allen key SW 8.  
Memorize the exact position of the washers.  
Remove the screw together with the chain  
roller from the frame. Change the chain roller.  
Lubricate the shaft of the screw..  
The surface of the chain roller features a „si-  
lent ring“ that is made of a long lasting elasto-  
mer. Depending on maintenance and care it  
has a life span of approx. 3000-5000 km.When  
this section is worn completely the links of the  
chain will run on the roller. In that case you  
will notice that the chain makes more noise  
while running and you should change the rol-  
ler.  
Push the screw through the chain roller, the  
washer and the spacer with the retention  
spring into the frame. Put on the washer on  
the left side, secure the thread with LOCTITE  
and tighten the nut with 14-16 Nm.  
The chain roller consists of two parts.After  
you have dismounted the chain roller you can  
tear the two halves apart and change the silent  
ring.  
Caution! The roller comes with two main-  
tenance free sealed bearings.The bearings  
are exchangeable. Between the bearings the-  
re is a spacer that keeps the correct distan-  
ce. If you forget to put in the spacer after  
you have dismounted the bearings they will  
be destroyed when you tighten the screw  
while remounting them.  
The bearings must not be treated with a jet of  
water from a high-pressure cleaner or with  
solvents since it destroys the seals and remo-  
ves grease in the bearings. If the bearings don't  
move smoothly anymore you'll have to replace  
them.

Suspension Fork  
Safety instructions  
Suspension fork  
Always check the correct position of brakes  
and wheels after you have worked on the sus-  
pension fork as described in the respective  
chapters. Check that the quick releases are  
tightly closed.  
Clean and grease your suspension fork regu-  
larly.  
Always use a high quality silicone or Teflon lu-  
bricant.You can purchase special lubricants for  
suspension forks at your local specialist dealer.  
The inner fork steerer tube is tightly fitted and  
glued in the fork crown, never try to tear this  
connection apart or to change the tube.  
If your suspension fork has lubricating nipples  
at the back you should insert a small amount  
of grease every four weeks.  
Never add threads to the steerer tube - danger  
of breaking!  
After six months at the latest the fork has to  
be lubricated again. For that purpose open the  
fork and dismount the parts as described in  
the following paragraph. If you are in doubt  
please have your bicycle mechanic do the  
work.  
The hydraulic damping cartridge is pressureri-  
zed and must not be opened. In case of damage  
the whole cartridge has to be replaced.  
Caution:After you have removed the adjust-  
ment screw (5) you'll see a small hex-headed  
screw in the piston rod of the damper: never  
undo this screw. It is under pressure. If this  
screw is undone too far it can damage the  
damper.  
If your suspension fork comes with a dust  
boot please clean the lower and upper leg and  
the seal under the dust boots every four  
weeks. Otherwise, dirt and water can lead to  
corrosion.  
Before every ride check the suspension fork  
for signs of damage, deformation or corrosion.  
If this is the case don't use your bicycle anymo-  
re.Ask your local dealer for service.  
Lubricate the legs regularly with a thin film.  
The following instructions refer to MEKS  
Carbon suspension forks. For other brands  
please see the instruction manual that comes

Exchanging springs  
Lubricating the fork / Dismounting  
In order to lubricate the fork have your bicy-  
cle mechanic dismount it completely.  
Gently turn the adjustment knob for the pre-  
load on the adjustment unit (9) clockwise as  
far as it will go.This causes the spring to relax.  
First remove the pre-load adjustment unit and  
springs as described under "Exchanging  
springs".  
If your spring has an adjustable damping (MEKS  
Carbon AC) turn the knob clockwise as far as  
it will go so that the fork does not decom-  
presses again.  
Undo and remove the screw M6 on the lower  
part of the leg (18).To prevent the push rod  
(14) from turning too press the fork together  
entirely and hold the push-rod with a long  
Allen key SW5.  
After you have relaxed the pre-load unit of the spring you can  
turn off the entire unit.  
Place a matching spanner or an adjustable  
wrench on the two parallel surfaces of the  
pre-load adjustment unit.Then remove the  
entire unit by turning it anti-clockwise.  
At the suspension fork MEKS Carbon All per-  
form the same work on the second spring  
strut. Now you can pull the upper part of the  
fork out of the lower part.  
Carefully remove the springs with one finger  
or the head of a spoke from the fork.  
Alternately put your bicycle upside down and  
catch the springs when they fall down.  
At the suspension fork MEKS Carbon AC re-  
move the screw on the lower part of the leg  
(19). Usually the damping cartridge (3) does  
not turn. However, when you have difficulties  
in removing the screw you can fix the cartrid-  
ge in the upper leg with a screw driver and  
thus prevent it from turning too. For this pur-  
pose, undo the entire damper adjustment unit  
Exchange the springs, lightly grease all parts  
and assemble the fork again in reverse order.  
After having finished the assembly please check by placing a wrench on the cap (8). Caution:  
if the fork works properly by compressing it  
several times manually.  
Never disassemble the adjustment unit (4, 5, 6,  
7, 8)!  
Clean all parts with a cloth. Grease the bus-  
hings, legs, springs and threads thoroughly and  
assemble the fork again.

Suspension Fork  
Exchanging the bushings  
The bushings of the suspension fork suffer  
from wear and tear through normal use. It de-  
pends on the use of the fork, the amount of  
dirt on it and the lubrication how long it lasts.  
If the bushings are worn the fork has too  
much play. Please have your specialist dealer  
replace the bushings in that case.

Rear suspension element  
If there is a safety ring at the thread of the  
Rear suspension element  
suspension element push it to the front so  
that you can undo the adjustment ring comple-  
tely and then turn it to the utmost position at  
the front. Remove the slotted spring retention  
disc at the rear end.  
Changing the spring  
You can buy the spring for the rear suspension  
element in different spring stiffnesses from  
your dealer.  
We recommend the following spring stiffnes-  
ses, depending on the overall weight:  
Danger! If the bicycle does not stand on  
the ground while undoing the screws of the  
suspension element the rear swing arm may  
come down uncontrolled afterwards and  
hurt you seriously. In addition to this the ca-  
bles of the gear system and the brakes may  
overstretch and you would have to replace  
them. Ensure that the rear swing arm comes  
down in a controlled and gentle fashion by  
putting up a solid string or cable tie bet-  
ween the main frame and the rear swing  
arm.  
up to 80 kg (183 lbs): 350 lbs./inch  
up to 100 kg (230 lbs): 450 lbs./inch  
up to 120 kg (275 lbs): 550 lbs./inch  
In addition to this your dealer can also use  
springs with other spring stiffnesses or special  
lightweight springs made of titanium.  
In most cases the stiffness is printed onto the  
spring.Take care to read the imprint carefully,  
since the term "B650" that sometimes occurs  
does not mean 650 lbs./inch!  
Spring lengths:  
DV22: 83 mm (70-90 mm)  
ST8ARC: 70 mm (65-76 mm)  
Danger! When the bicycle is standing on  
the ground the frame and the swing arm co-  
me up against each other. Please make sure  
that this happens in a controlled and gentle  
fashion. Put a cloth between the contact po-  
ints. Otherwise, if they come up against each  
other uncontrolled your hands may get  
caught between main frame, rear arm swing  
and suspension element and your bicycle  
may be damaged.  
In order to change the spring you will have to  
remove the rear screw and swing away the re-  
ar frame.  
Hold the main frame of your bicycle in a work  
stand.  
In case you have a suspension element with  
adjustable damping first remove the rear ad-  
justment knob for the damping control by un-  
doing the small screw at the side with an Allen  
key and by then pulling of the knob.  
Undo the screws of the rear suspension ele-  
ment with two Allen keys and push the screw  
out of the suspension element eye.

Rear Suspension Element  
Move the rear swing arm down carefully. In  
doing this, take care that you don't bend or  
stretch any cables.  
Cleaning and lubricating  
Do clean the suspension element, especially  
the polished piston rod, if it is dirty. Remaining  
dirt and sand can damage the seals of the hy-  
draulic system and so shorten its life consider-  
Remove the spring from the suspension ele-  
ment and put in the exchange spring. Make su- ably.When you often use dirty roads you can  
re that the new spring has the same diameter  
and length as the old spring and that it lies sa-  
fely on the adjustment ring.  
protect the suspension element from dirt with  
an elastic cover that you can buy at your local  
dealer.  
Put back the slotted rear spring retention disc  
on the piston rod. If necessary, compress the  
spring a little bit with a screw driver.The  
spring retention disc has to match its seating  
at the rear end of the suspension element.  
From time to time grease the thread for the  
spring pre-load with a drop of acid-free oil.  
Thus, you can always turn the adjustment ring  
easily by hand. Once a year you have to grease  
the pivots of the suspension element. For that  
purpose dismount the suspension element as  
Secure the spring by tightening the adjustment described under "Changing the Spring" on pa-  
ring until the spring doesn't have any play any-  
more. If there is a safety ring, push it back into  
the slot on the thread.

suspension element.  
Secure the screws of the suspension element  
with LOCTITE and tighten the screw with 6-8  
Nm.  
In case you have a suspension element with  
adjustable damping put back the adjustment  
knob on the small rod, turn it so that the  
screw fits exactly and noticeably to the flat  
part of the rod and tighten the screw again.  
The bushings of the rear spring element need to be lubricated  
once a year.  
After having exchanged the spring you have to  
readjust the spring pre-load as described in  
the chapter on "Adjusting your new bicycle"  
on page 18.

Swing arm pivot  
The bushings are exchangeable. For that pur-  
pose you will have to dismount the rear swing  
arm and send it together with the axle via  
your specialist dealer to HPVELOTECHNIK.After  
having been mounted the bushings are machi-  
ned to adjust them.  
Swing arm pivot  
The rear swing arm pivot comes with mainte-  
nance free bushings.They have a self lubricating  
system with Teflon particles.The bushings  
sustain a very high load and they show almost  
no wear.  
Undoing the axle screws  
In case you notice play or a creaking noise at  
the rear swing arm please check the two  
screws that keep the axle in the frame.They  
will have to be secured with LOCTITE.  
In order to mount the rear rack or the lowri-  
der the axle screws have to be undone.We re-  
commend you to leave one screw in place to  
prevent the axle from turning.  
Tightening torques:  
Mushroom head screw M8x25 (without rear  
rack): 14-16 Nm  
In case the rear swing arm is to be dismoun-  
ted completely you can prevent the axle from  
turning by inserting a thin metal rod in the ho-  
le of the axle through the drilling of the rear  
swing arm under the axle.  
Screw M8x45: 17-19 Nm  
Danger! If the screws at the axle are not  
tight enough this leads to play and noises  
when the spring compresses. In extreme ca-  
ses the swing arm may come loose which le-  
ads to a serious fall. If the screws are too  
tight the thread of the axle may tear out or  
the screw may be damaged.  
Caution! There has to be a big washer bet-  
ween the main frame and the end of the  
bushing else the busing is not able to func-  
tion without play and the frame will be da-  
maged.  
You can prevent the axle from turning by inserting a thin metal  
rod in the hole of the axle.

Seat  
Seat  
For transport purposes you can dismount the  
seat. For that purpose open the quick releases  
and unscrew the knurled nuts from the axle.  
Then remove the quick releases and catch the  
washers that come out too.To remount the  
seat, do all the steps in reverse order.  
Interchanging the seats  
In principle you can interchange the different  
seat sizes and the seats of the Street Machine  
Gt with the Speedmachine.  
If the adjusting range of 10° cannot fully be  
used after you have exchanged the seat you  
will have to slightly reposition the slotted alu-  
minum fittings at the seat.  
For that purpose, take off the seat cushion.  
Undo the self-locking nuts of each of the 4  
screws of the upper and lower seat fastening  
by several turns.The holes in the aluminum fit-  
tings are slightly bigger than the diameter of  
the screws so that you can move the alumi-  
num fittings up or down to find the biggest ad-  
justing range possible.  
Finally tighten all screws of the seat fastening  
by 8-10 Nm.  
Screws that are not tight enough may lead to  
cracking noises while riding and may damage  
the seat.

Seat Cushion  
For better ventilation, an airflow cushion is  
available as accessory.This cushion consists of  
several layers:A soft foam and a rigid mesh,  
which provides for an approximately 1 cm  
thick air cushion with excellent circulation.  
These two layers are wrapped up in a cover  
that consists of fine mesh like it is known from  
high quality Rucksacks.  
Seat cushion  
The standard seat cushion consists of a 1,4 cm  
thick layer of flexible EVA foam.This is a black  
material with closed cells that is also used in  
the production of high quality camping mats. It  
feels very comfortable without appearing too  
soft or spongy. It is waterproof so that you can  
dry your seat with a sweep of your hand in ca-  
se your bicycle has become wet.  
You can wash the material at 30° Celcius and  
it dries very quickly. In case you want to wash  
the seat cushion take it off the seat.Then open  
theVelcro at the back and take out the foam  
cushion and the airflow insert.  
Caution! The seat cushion is fastened with  
Velcro and you can take it off. For this pur-  
pose it is important not to simply grab the  
foam and take it off since theVelcro could  
come off. In order to take off the seat cus-  
hion lift up the upper part a little bit from  
the seat.Then you grab the cushion on both  
sides together with the end of theVelcro  
that sticks out slightly and remove the cus-  
hion slowly. In case theVelcro comes off  
fasten it again with a good glue.  
The seat cushion suffers from wear through  
constant use.At the parts that are under punc-  
tual strain the mesh can be pressed together  
permanently. In order to provide a good riding  
comfort in that situation the airflow cushion  
has additional foam padding.  
Caution! Never expose the seat cushion to  
extreme heat or focused sunlight.The mate-  
rial warms up considerably.The heat may  
melt the glue of theVelcro.The seat cushion  
can be damaged when the rays of the sun  
are bundled through a lens.Take care to ne-  
ver leave any bubble wrap on the seat in the  
sun.The air bubbles in the film act like a  
burning glass and shrink the seat cushion.

Water bottle Cage, Mudguards  
Another useful alternative to water bottles are  
Water bottle cage  
systems with a "water bag" and a drinking ho-  
se, e.g. from SOURCE or CAMELBAG.You can sim-  
ply strap them behind the seat, onto the rear  
rack or into the Speedbag.  
You can mount a water bottle cage at the side  
of the seat, under the frame between the  
wheels or at the front derailleur tube.The  
main frame tube and the derailleur tube at the  
front of the frame come already with threa-  
ding inserts M5 for that purpose.  
Mudguards  
At bicycles with suspension mudguards are ex-  
posed to very strong vibrations through which  
they may break. Please check the stays of the  
mudguard regularly for their position and  
check the mudguards for cracks or deforma-  
tions. Immediately replace damaged mud-  
guards.  
You can mount a water bottle cage at the left  
or right side of the seat so that you can com-  
fortably reach it while riding. For that purpose  
you can drill two holes into the outmost edge  
of the seat.To fasten the cage use screws with  
big heads or big washers in order not do da-  
mage the fiberglass of the seat.Another good  
alternative is the position at the back of the  
seat between the shoulders where you can al-  
so comfortably grab the bottle while riding.  
Caution!You must not mount additional  
parts like rear lights or reflectors to the  
mudguards since those may break then.  
In order to prevent falls you have to fasten the  
stays of the front mudguard with a security  
clip that opens under pressure.When the clip  
has opened once please replace it with a new  
one.  
Danger! If branches or other obstacles get  
caught in the wheels while riding and are  
moved around they may drag the mudguards  
along.The mudguard can possibly fold up  
between frame and tire and hence block the  
wheel, which may lead to a serious fall. If you  
hear any unknown noises while riding stop  
immediately and remove anything that might  
cling to the mudguards or the wheels.  
An ideal position for water bottle cages is at the side of the seat.  
Caution! Do not drill any holes into other  
seat areas than those indicated above. It is  
especially important not to damage the rein-  
forcing ribs.

Mudguards,Wheels  
Alternatively you can mount the stays at the  
two outer screws of the U-brace or fasten it  
with a clip in the middle of the lower leg of  
the suspension fork.  
After you have performed service work or re-  
placed mudguards check if the wheels turn  
freely. Between mudguard and wheel has to be  
a distance of at least 7 mm.  
Check whether the suspension can still fully  
compress with themounted mudguards.The  
mudguards, stays and screws (especially at the  
U-brace of the suspension fork) must not  
touch other parts under maximum compres-  
sion.  
Before pumping up the tire, you have to undo the little knurled  
nut on the valve.  
Now you see a small threaded rod with a  
knurled nut that comes out of the valve. Undo  
the knurled nut by loosening it as far as it  
goes.  
Wheels  
To pump up the tire and check the pressure  
you need a pump with a gauge, preferably a so-  
lid standing air pump. Put the knob of the  
pump on the valve, push it completely on the  
valve and then retract it a little bit. Now you  
can pump up your tire easily.  
The correct air pressure is decisive for  
smooth running and a good protection against  
punctures.The maximum pressure is printed  
on the side of your tire. Since your Street  
Machine GT is fully suspended you can always  
go for the maximum pressure.You might find  
an indication of the minimum required pressu-  
re on the side of the tire as well.  
After you have pumped up the tire to the ma-  
ximum pressure pull off the pump knob.  
Secure the valve through turning the knurled  
nut on the threaded rod as far as it will go to-  
wards the valve. Finally put on the valve cap  
again.  
Since the tubes in the tires gradually loose air  
you should check the air pressure before eve-  
ry ride.  
The tubes come with Presta valves (also called  
french valves).They are very airtight and easy  
to pump up. For that purpose first undo the  
valve cap.  
Danger! Never pump up your tires beyond  
the maximum pressure.The tire may burst  
while riding or come off the rim, which may  
result in a serious fall.

Wheels, Cleaning and conservation  
Danger! Check your tires for damage on a  
regular basis.You should exchange tires with  
worn threads or damaged sidewalls.  
Damaged rim tapes have to be exchanged  
immediately. Damages at the tires may lead  
to a sudden burst of the tire and thus result  
in a serious fall.  
Caution! To true up the wheels you need  
special skills, please have this work done by  
an experienced bicycle mechanic.  
The wheels are fastened with a quick release  
lever and therefore they are susceptible to  
theft. For this reason always lock the wheels  
along with the frame to a solid object when  
you park your bicycle somewhere. It is also  
possible to exchange the quick release axles  
with axles that have special security locks (e.g.  
PITLOCK or KRYPTONITE) that can only be ope-  
ned with a special tool.  
When you exchange tires please note the ma-  
ximum width limit of 50 mm (approx. 2 ").We  
recommend tires that are 32-40 mm wide.At  
the front wheel you have to use tires of ISO  
size 406 (20"), at the rear wheel ISO size 559  
(26").The tire width possible at your bicycle  
depends on the size of your rims. Please ask  
your local dealer.  
Cleaning and conservation  
The frame of the Street Machine GT has a  
high quality and environmentally friendly pow-  
der coating.The surfaces of the aluminum  
parts are either polished or anodized.  
After you have exchanged the tires please  
check if the wheels turn freely and check the  
minimum distance between mudguards and  
frame.  
To keep the surfaces brilliant over many years  
and to protect them effectively against corro-  
sion the bicycle has to be cleaned from dirt  
and then conserved.  
The spokes of the wheels connect the rim  
with the hub.With disc brakes and at the rear  
wheel they additionally transmit the braking  
power and the pedal forces.  
Dried sweat but also environmental influences  
such as air pollution, dirt on the roads and es-  
pecially grit affect the parts, and not only do  
they result in visual faults but also in serious  
structural damage of the parts through corro-  
sion.  
Danger! Take care that your spokes are al-  
ways in perfect condition and the spoke ten-  
sion is balanced. Do not ride with wheels  
that run untrue or wheels with loose or  
missing spokes.These faults may lead to a  
total failure of the wheel while braking and  
result in a serious fall!  
In contrast to a widespread belief particularly  
the "non-rusting" aluminum is dramatically af-  
fected by grit! This kind of damage may not be  
visible in the beginning but it leads to a serious  
danger when the part breaks.

Do clean and conserve your bicycle diligently!  
In case of small scratches at the surface of the  
powder coating of the frame or the surface of  
the seat or the Speedbag you can simply polish  
them away.You can buy a special polishing  
The best things to clean your bicycle with are  
warm water and a soft cloth. If your bicycle is  
very dirty first take a wet sponge to soften the agent for epoxy resins at a specialist dealer for  
dirt and then remove it. In case of bad grease  
or oil stains you should use a special cleansing  
agent for bicycles in addition.  
boat building. Do not use a polish for metal!  
After you have cleaned the bicycle, dry it and  
treat the paintwork and the metal surfaces  
with wax.You can purchase this wax from your  
local bike dealer as a convenient spray.  
Caution! Do not use any cleansing agents  
that scrub or are chemically aggressive since  
they affect the paintwork. Before using any  
cleansing agent please test it at a part of  
your bicycle that is not immediately visible.  
The wax passes moisture and flows into tiny  
gaps and pores.After some minutes the sol-  
vent evaporates and leaves a dull and glutinous  
film. Now polish the waxed parts of your bicy-  
cle with a soft cloth to make it real shiny.  
Caution! Do not use any high-pressure cle-  
aner.The strong jet of water goes through  
the seals of the bearings, blows away the lu-  
be and causes corrosion of the bearing parts  
and the chain. In addition to this it may da-  
mage stickers.  
Do not only wax the frame but also the spo-  
kes, hubs, screws and nuts etc.You can also  
conserve the chain with wax spray after lubri-  
cating it, see also the chapter on "Chain", page  
36.  
The frame has small holes for ventilation that  
prevent condensation in the frame.These dril-  
While cleaning your bicycle check it for any  
cracks, scratches, deformations, damaged parts, ling holes must not be sealed. However, mo-  
looses spokes etc. If you are in doubt please  
consult your local bike shop.  
isture may enter the frame through the drilling  
holes.Therefore protect the inside of your fra-  
me by applying wax spray through the holes.  
Caution! Any damage of the paintwork has  
to be cleaned from rust and repaired imme-  
diately, else the damaged part in the frame  
gives way to corrosion that nests in the sur-  
rounding paintwork.This can result in dama-  
ge of the frame.  
Protect the parts where cables or chain tubes  
may scratch the frame with a layer of tape.You  
can buy extra strong transparent tape at your  
do-it-yourself-store.That way you avoid scrat-  
ches in the powder coating and coating co-  
ming off.

Storing the bicycle, Screws and bolts  
Do use high quality acid free grease, if possible  
Storing the bicycle  
a lubricant with added solid particles like  
Teflon or MoS2.Their ingredients still work  
properly after the thinner grease has been re-  
moved from the contact points.  
Before you are going to store your bicycle  
over a longer period of time, e.g. over winter,  
please take care of the following steps:  
G Clean your bicycle and protect it from  
corrosion as described in the chapter on  
"Cleaning".  
G Store your bicycle in a dry and warm place.  
G Avoid direct sun and storage close to the  
heating since it affects the rubber of your  
tires.  
G Choose the smallest sprocket and the  
smallest chain ring.That way the cables are  
in the most relaxed position.  
G The tubes of your tires loose air when  
standing over a longer period of time. If the  
bicycle then rests on flat tires the tires may  
be damaged.Therefore hang up your bicycle  
or check the air pressure regularly.  
Alternatively you can use LOCTITE screw secu-  
ring fluid that you apply to the screw before  
you put it into the thread.  
Always check the screws very diligently for  
signs of corrosion. Rust at the screw heads  
may also lead to the screw seizing in the thre-  
ad.When the metallic and shiny coating of gal-  
vanized screws comes off and discloses dull,  
gray-brown steel you have to exchange the  
screw.  
When you exchange screws please do only  
use screws of the same type. Screws come in  
different strength classes. Please do only use  
galvanized screws of the same type and  
strength, corresponding to the German  
strength classes 8.8 or stainless steel screws  
grade A2, when not given any other recom-  
mendation. If you are in doubt please ask your  
specialist dealer.  
The winter months are a convenient period of  
time for the annual service since then you wo-  
n't have to wait long for an appointment. Many  
dealers offer special prices for the winter  
check.  
Screws and Bolts  
Screws gradually settle in and through this  
they can come loose.Therefore check the  
screws and bolts regularly if they are tightened  
appropriately with a torque wrench.  
In the following table you will find the prescri-  
bed tightening torques, they refer to greased  
screws!  
The grease also prevents your screws from  
seizing in their threads so that they won't un-  
screw anymore. In particular, screws made of  
stainless steel are susceptible to this and the-  
refore have always to be put in with grease.

damaged frame to us so that we can check it,  
if asked to do so by us.We do not take over  
any secondary costs.  
Warranty  
Your authorized dealer has to fully set up and  
adjust your bicycle, so that safe function is  
guaranteed.The dealer has to make a final safe-  
ty check and carry out a test ride.  
In case of warranty we will cover the costs for  
the transport within the usual limits (postal  
service). In case of warranty we will replace  
the damaged part with a part of our choice or  
a new part equal to the old one (warranty ob-  
ligation).  
Your cycle dealer is obliged by law to ensure,  
among other things, that your bicycle is not af-  
fected by defects which materially diminish its  
value of suitability for the described purpose.  
The exact details will vary according to the  
country. In Germany, this liability ends two  
years after purchase.  
In the event of any action that falls under war-  
ranty the original warranty period will not be  
prolonged and no new warranty will be given.

ding through excess weight, incorrect assembly  
or modifications to the bike is also not cove-  
red.The onus rests with the purchaser.The  
warranty is void if any of the instructions in  
this manual are neglected.

pass at the end of this manual has been filled  
in when you received your bike and when  
every inspection listed has been done and  
recorded by your bicycle mechanic within the  
described time schedule.

The service intervals given in this Warranty  
Pass refer to an average use and a riding per-  
formance of 3.000 km per year.  
The regular service maintains the safe opera-  
tion and the value of your bicycle. Not only  
does the completed Warranty Pass record the  
maintenance works for the validation of your  
warranty but also does it proove the care and  
the value of your bicycle - a good thing to  
have when you are going to sell your Street  
Machine Gt one day.  
When you ride more kilometers per year or  
often ride under bad conditions like rain, grit  
or other dirty factors it is necessary to have  
shorter maintenance intervals.  
In order to measure your riding performance  
we recommend you to use a bicycle computer.
