Remove contents from box. Remove the foam separators that protect the components from damage during
shipping. Inspect the contents of the box for scratches in the paint, dents or kinked cables that may have
occurred during shipping. Because the Dirt Rocket is 95 percent assembled and packed at the factory, there
should not be any problems, even if the box has a few scars or dents.

warnIng:
Failing to properly adjust and
tighten the nuts and bolts that
affix the fork can cause you to
lose control and fall.

through the other side of the wheel hub, add the other spacer and
slide though the fork. Secure with washer and nut.
Note: Front axle is installed with the spacer between the fork and
wheel for all Dirt Rockets.
Note: If your model has one short spacer, it goes on the side of the
hub with the disc brake.
Note: where front axle is located in box.
3With a 14mm and 17mm
open wrench tighten the front
wheel screws.
Inflating the Tires
Note: The pressurized air
Tires are inflated when shipped, but they invariably lose some pressure between the point of
manufacturing and your purchase.
supplies found at gasoline
stations are designed to inflate
high-volume automobile tires.
If you decide to use such an
air supply to inflate your tires,
first make sure the pressure
gauge is working, then use very
short bursts to inflate to the
correct PSI. If you inadvertently
over-inflate the tire, release the
excess pressure immediately.
Using a bicycle tire pump equipped for Schrader valves, inflate the tires to the PSI indicated on
the sidewall of the tire.

BefOre rIDIng
charging the Battery
Your electric motorbike may not have a fully charged battery; therefore it is a good idea to charge the
battery prior to use.
warnIng:
Always disconnect your electric
motorbike from the charger before
cleaning with liquid.
• Initial charge time: 12 hours
• Run time: Up to 40 minutes of continuous ride time
Run time may vary depending on riding conditions,
climate and/or proper maintenance.
• Average battery life: 250 charge/discharge cycles
• To ensure long battery life, do not store the battery
in temperatures above 75° or below -10° F.
• Recharge time: up to 12 hours,
depending on level of depletion.
• Fully charge battery before storing.
• When the scooter is not in regular use,
recharge the battery at least once a
month until normal use is resumed.
Note: If your charger does not
look like the one illustrated,
your unit has been supplied
with an alternative charger.
The specifications and charging
procedure would not change.
Charger
The charger has a small window
with one LED to indicate the
charge status. Refer to the
illustration on the charger unit
for the actual “charging” and
“charged” status indications for
your model charger.

Chargers have built-in over-charge

essary, try a different outlet.
before charging. Plug charger
into the charger port on the
electric motor bike.
Charger will get warm during use.
This is normal for some chargers
and is no cause for concern. If
your charger does not get warm
during use, it does not mean that
it is not working properly.
Be sure to properly align the
groove on the charger input
plug with the corresponding
socket on the case; otherwise,
no charging action will occur.

causing the electric motorbike
to skid the tire throwing an
unsuspecting rider. Practice
in an open area free from
obstacles until you are familiar
with the brake function. Avoid
skidding to a stop as this can
cause you to lose control or
damage the rear tire.
q adjusting the Brakes
Tools required: 5mm Allen wrench
2 If the brake has too much
slack, loosen the rear anchor
bolt with a 5mm Allen wrench
and pull the brake wire tighter.
The distance of the brake wire
between the end of the cable
and the anchor bolt should be
between 37mm and 44mm.
3 If the brake rotor is
dragging on the brake pads,
use your fingers to twist the
caliper adjuster in either
direction until rotor is cen-
tered between pads.
1 To adjust the tension, thread
the brake lever adjuster in or
out 1/4 to 1/2 turn until the
desired brake adjustment is
attained. Most adjustments are
complete at this step. If brake
still needs further adjustment,
proceed to step 2 for rear brake.
q Testing the Brakes
To use the brakes, squeeze the levers to increase the pressure on the brake. The brake levers are fitted
with a cable adjuster to compensate for cable stretch and/or to fine-tune the lever movement to brake
engagement. If brakes are not engaging properly, follow instructions for adjusting the brakes outlined below.

warnIng:
Regularly check the spoke
tension and retighten the
spokes whenever loose. If
you have any doubt, ask an

your spokes to determine if
the spokes need tightening or
adjusting.

1Verify the spoke tension by shaking each spoke with your fingers.
Spoke should not be loose from hub. Look for any play between
where the spoke flanges attach to the hub. Try to turn the nipple us-
ing your fingers. You should not be able to spin any nipple by hand. If
one or more spokes is loose, all spokes must be checked and need to
be tightened with a spoke wrench.
2 Start with spoke closest to the
tire valve stem and tighten each
nipple, in sequence, exactly 1/4
to 1/2 turn. A single 1/4 to 1/2
turn may not be enough to bring
the spokes into proper tension.
Continue tightening all spokes no
more than 1/2 turn in sequence
until all spokes are tight.
Note: More than a 1/2 turn each
can cause the wheel to become
distorted and wobbly thus perma-
nently damaging the wheel.
q chain and sprocket
warnIng:
The chain will typically have a “loose spot” and “tight spot” corresponding with a particular sprocket
rotational position. This is normal and common to all chain driven products due to run-out tolerances of the
freewheel and sprocket. The chain should be adjusted to the ideal tension with chain in the tightest spot.
To avoid a pinch or injury, keep
fingers away from moving
sprockets and chain.
Proper chain alignment must be maintained. The wheel must not be skewed. If the chain is noisy or rough
running, check the lubrication, tension and alignment of the sprockets, in that order.

The fuse will burn out and automatically shut off the power if the
motor is overloaded.
An excessive overload, such as too heavy a rider or too steep a hill,
could cause the motor to overheat. Replace the fuse(s) with a new one
of equal amperage. Correct the conditions that caused the fuse to burn
out and avoid repeatedly burning out fuse.
