WARNING: Riding an electric motorbike can be a hazardous activity.
Certain conditions may cause the equipment to fail without fault of the
manufacturer. Like other electric vehicles, the Dirt Rocket can and is intended
to move, and it is therefore possible to lose control, fall off and/or get into
dangerous situations that no amount of care, instruction or expertise can
eliminate. If such things occur you can be seriously injured or die, even when
using safety equipment and other precautions. RIDE AT YOUR OWN RISK
AND USE COMMON SENSE.
This manual contains many warnings and cautions concerning the
consequences of failing to maintain, inspect or properly use your electric
motorbike. Because any incident can result in serious injury or even death, we
do not repeat the warning of possible serious injury or death each time such a
possibility is mentioned.
APPROPRIATE RIDER USE AND PARENTAL SUPERVISION
This manual contains important safety information. It is your responsibility to
review this information and make sure that all riders understand all warnings,
cautions, instructions and safety topics and assure that young riders are able
to safely and responsibly use this product. Razor USA recommends that you
periodically review and reinforce the information in this manual with younger
riders, and that you inspect and maintain your children’s vehicle to insure their
safety.
The recommended rider age (12 years for the MX350, 14 for the MX500, and
16 for the MX650) is only an estimate, and can be affected by the rider’s size,
weight or skills. Any rider unable to fit comfortably on the Dirt Rocket should
not attempt to ride it.
A parent’s decision to allow his or her child to ride this product
should be based on the child’s maturity, skill and ability to follow
rules.
Keep this product away from small children and remember that this product
is intended for use only by persons who are, at a minimum, completely
comfortable and competent while operating the vehicle.
DO NOT EXCEED THE WEIGHT LIMIT OF 140 pounds for the MX350, 175
pounds for the MX500, and 220 pounds for the MX650. Rider weight does not
necessarily mean a person’s size is appropriate to fit or maintain control of the
Dirt Rocket.
Do not touch the brakes or electric motor on your electric motorbike when in
use as they can become very hot.
Refer to the section on safety for additional warnings.
ACCEPTABLE RIDING PRACTICES AND CONDITIONS
Always check and obey any local laws or regulations which may
affect the locations where the Dirt Rocket may be used.
Ride defensively. Watch out for potential obstacles that could catch your
wheel or force you to swerve suddenly or lose control. Be careful to avoid
pedestrians, skaters, skateboards, scooters, bikes, children or animals who
may enter your path, and respect the rights and property of others.
The Dirt Rocket is meant to be used only in controlled environments free of
potential traffic hazards and not on public streets or sidewalks. Do not ride
your electric motorbike in any areas where pedestrian or vehicle traffic is
present.
Do not activate the speed control on the hand grip unless you are on the
electric motorbike and in a safe, outdoor environment suitable for riding.
These bikes were manufactured for performance and durability but are not
impervious to damage. Jumping or other aggressive riding can over-stress
and damage any product, including the electric motorbike, and the rider
assumes all risks associated with high-stress activity.
Be careful and know your limitations. Risk of injury increases as the degree
of riding difficulty increases. The rider assumes all risk associated with
aggressive riding activities.
Maintain a hold on the handlebars at all times.
Never carry passengers or allow more than one person at a time to ride the
electric motorbike.
Never use near steps or swimming pools.
Keep your fingers and other body parts away from the drive chain, steering
system, wheels and all other moving components.
Never use headphones or a cell phone when riding.
Never hitch a ride with another vehicle.
Do not ride the Dirt Rocket in wet or icy weather and never immerse the
electric motorbike in water, as the electrical and drive components could be
damaged by water or create other possibly unsafe conditions.
The Dirt Rocket is intended for use on flat, level ground without loose debris
such as rocks or gravel. Wet, slick, bumpy, uneven or rough surfaces may
impair traction and contribute to possible accidents. Do not drive the electric
motorbike in mud, ice, puddles or water. Avoid excessive speeds that can be
associated with downhill rides. Never risk damaging surfaces such as carpet
or flooring by use of an electric motorbike indoors.
Do not ride at night or when visibility is limited.
PROPER RIDING ATTIRE
Always wear proper protective equipment such as an approved safety helmet
(with chin strap securely buckled), elbow pads and kneepads. A helmet may
be legally required by local law or regulation in your area. A long-sleeved
shirt, long pants and gloves are recommended. Always wear athletic shoes
(lace-up shoes with rubber soles), never drive barefooted or in sandals,
and keep shoelaces tied and out of the way of the wheels, motor and drive
system.
USING THE CHARGER
The charger supplied with the electric motorbike should be regularly
examined for damage to the cord, plug, enclosure and other parts, and in the
event of such damage, the bike must not be charged until the charger has
been repaired or replaced.
Use only with the recommended charger.
The charger is not a toy.
Always disconnect from the charger prior to wiping down and cleaning your
electric motorbike with liquid.
FAILURE TO USE COMMON SENSE AND HEED THE ABOVE
WARNINGS INCREASES RISK OF SERIOUS INJURY. USE WITH
APPROPRIATE CAUTION AND SERIOUS ATTENTION TO SAFE
OPERATION.

CONTENTS
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.
Estimated Assembly and Set-Up Time
Razor recommends assembly by an adult with experience in bicycle mechanics.
Allow up to 30 minutes for assembly, not including initial charge time.
Allow up to 12 hours for initial charge (see page 3 for charging information).

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.
The charger has a small window
with one LED or two LEDs 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
protection to prevent battery from
being over-charged.
Be sure to properly align the

1 To adjust the play, 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.
2 If the brake lever adjuster is
threaded outward and the brake
still has too much slack, use the
back brake adjuster at the rear
brake for additional adjustment.
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.

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
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.
37-44 mm

1 To adjust the play, 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.
Inflating the Tires
Tires are inflated when shipped, but they invariably lose some pressure between the point of
manufacturing and your purchase.
Note: The pressurized air
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.
