BEFORE YOU BEGIN  
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 was 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:  
DO NOT USE NON-RAZOR

ASSEMBLY AND SET-UP  
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  
• Recharge time: up to 8 hours,  
depending on the level of depletion  
• Run time: up to 40 minutes  
• Average battery life: 250 charge/discharge cycles  
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  
Port  
The charger has a small window  
with one LED or two LEDs to  
indicate the charge status. Refer

ASSEMBLY AND SET-UP  
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-style tire pump equipped for a Schrader-type valve, inflate the front tire to the PSI indicated  
on the sidewall of the tire.  
Testing the Brakes  
To use the brake, squeeze the lever to increase the pressure on the brake. The brake lever is fitted  
with a cable adjuster to compensate for cable stretch and/or to fine-tune the lever movement to brake  
engagement. If brake is not engaging properly, follow instructions for adjusting the brakes outlined below.  
REPAIR AND MAINTENANCE  
Check the Razor web site for any updates on the latest repair and maintenance procedures.  
Turn power switch off before conducting any maintenance procedures.  
q Adjusting the Brakes  
WARNING:  
The brake is capable of

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.

2 If the brake has too much  
slack, loosen the rear anchor  
bolt 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 44 mm.  
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.

brake adjustment is attained.  
Most adjustments are complete  
at this step. If brake still needs  
further adjustment, proceed to  
step 2 for rear brake.

WARNING:  
Regularly check the spoke

1Verify spoke tension by grasping and shaking each spoke. Spoke  
should not be loose from hub. Look for any play between spoke flang-  
es where it mates with hub. Try to turn nipple using your fingers. You  
should not be able to spin any nipple by hand. If one or more spokes  
are loose, or if you can turn any nipple using your fingers, all spokes  
must be checked and need to be tightened with a spoke wrench.  
2Start with spoke closest to  
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: Tightening each nipple  
more than a 1⁄2 turn each can  
cause the wheel to become  
distorted and wobbly thus  
permanently damaging the  
wheel.

REPAIR AND MAINTENANCE  
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 vehicles 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.  
q Battery Care and Disposal  
Do not store the battery in temperatures above 75° F or below -10° F.  
CONTAINS SEALED LEAD BATTERY. BATTERY MUST BE RECYCLED.  
WARNING:  
Disposal: Your Razor product uses sealed lead-acid batteries which must be recycled or disposed of in  
an environmentally sound manner. Do not dispose of a lead-acid battery in a fire. The battery may explode  
or leak. Do not dispose of a lead-acid battery in your regular household trash. The incineration, land filling  
or mixing of sealed lead-acid batteries with household trash is prohibited by law in most areas. Return  
exhausted batteries to a federal or state approved lead-acid battery recycler or a local seller of automotive  
batteries. If you live in Florida or Minnesota, it is prohibited by law to throw away lead-acid batteries in the  
municipal waste stream.  
If a battery leak develops, avoid  
contact with the leaking acid  
and place the damaged battery  
in a plastic bag. Refer to the  
disposal instructions at left. If  
acid comes into contact with  
skin or eyes, flush with cool  
water for at least 15 minutes  
and contact a physician.  
q Charger  
The transformer/charger supplied with the bike should be regularly examined for damage to the cord, plug,  
enclosure and other parts, and, in the event of such damage, the Dirt Rocket must not be charged until it  
has been repaired or replaced.  
Use ONLY with the recommended charger.  
q Replacement Parts  
The most frequently requested replacement parts (wheels, tires, tubes, batteries and chargers) are

TROUBLESHOOTING GUIDE  
Problem  
Possible Cause  
Solution  
Vehicle does not run  
Undercharged battery  
Charge the battery. A new battery should have been charged for at  
least 12 hours before using the vehicle for the first time and up to 8  
hours after each subsequent use.  
Check all connectors. Make sure the charger connector is tightly  
plugged into the charging port, and that the charger is plugged into  
the wall.  
Make sure power flow to the wall outlet is on.  
Charger is not working  
You may check to see if your charger is working by using a volt meter or  
asking your local Razor authorized service center to test your charger  
for you.  
Loose wires or connectors  
Burned-out fuse  
Check all wires and connectors to make sure they are tight.  
Vehicle was running but  
suddenly stopped  
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 with a new one  
of equal amperage. Correct the conditions that caused the fuse to burn  
out and avoid repeatedly burning out fuse.  
Motor or electrical switch damage  
Contact your local Razor authorized service center for diagnosis and  
repair.  
Short run time (less than Undercharged battery  
30 minutes per charge)  
Charge the battery. A new battery should have been charged for at  
least 12 hours before using the vehicle for the first time and up to 8  
hours after each subsequent use.  
Check all wires and connectors. Make sure the battery connector is  
tightly plugged into the charger connector, and that the charger is  
plugged into the wall.  
Make sure power flow to the wall outlet is on.  
Battery is old and will not accept full  
charge  
Even with proper care, a rechargeable battery does not last forever.  
Average battery life is 1 to 2 years depending on vehicle use and  
conditions. Replace only with a Razor replacement battery.  
Brakes are not adjusted properly  
Driving conditions are too stressful  
Refer to brake adjustment instructions on page 5 of this manual.  
Use only on solid, flat clean and dry surfaces such as pavement or  
level ground.  
Vehicle runs sluggishly  
The tires are inflated when shipped, but they invariably will lose some  
pressure between the point of manufacturing and your purchase. Refer  
to instructions on page 4 and 5 of this manual to properly inflate tires.  
Tires are not properly inflated  
Vehicle is overloaded  
Make sure you do not overload the vehicle by allowing more than  
one rider at one time, exceeding the maximum weight limit, going up  
too steep a hill or towing objects behind the vehicle. If the vehicle is  
overheated, the temperature circuit protector will slow motor down  
and if the condition continues, will shut off power to the motor. Correct  
the driving conditions that caused the overheating, wait 5-10 minutes  
and then resume riding. Avoid repeatedly overheating the unit.

SAFETY REMINDERS  
PRE-RIDE CHECKLIST  
Loose Parts  
Tire Inflation  
There should not be any unusual rattles or sounds from  
loose parts or broken components. If you are not sure, ask  
an experienced mechanic to check.  
Periodically inspect the tires for excess wear and replace as  
required, and regularly check the tire pressure and re-inflate  
as necessary. If you get a flat tire, the inner tube can be  
patched or a new tube can be purchased from Razor or an  
authorized repair center.

Brake  
Check the brake for proper function. When you squeeze the  
lever, the brake should provide positive braking action.  
Safety Gear  
q
q
Always wear proper protective equipment, such as an  
approved safety helmet, elbow pads and kneepads. Always  
wear shoes, never drive barefooted or in sandals, and keep  
shoelaces tied and out of the way of the wheels, motor and  
drive system.  
Frame, Fork and Handlebars  
Check for cracks or broken connections. Although broken  
frames are rare, it is possible for an aggressive driver to  
bash into a curb or wall and wreck and bend or break a  
frame. Get in the habit of inspecting yours regularly.  
DO NOT RETURN TO STORE  
Do not use this vehicle for the first time until you  
have inflated the tires to the correct PSI and  
charged the battery for at least 12 hours.  
Failure to follow these instructions may damage  
your vehicle and void your warranty.
