SAFETY WARNINGS
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 products, 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 product to insure their
safety.
The recommended rider age of 13 years (MX350/MX400) 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 products.
Do not exceed 140lbs. (63kgs.) total weight on the MX350 and MX400. 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 motor bike 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 objects 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 motor bike in any areas where pedestrian or product traffic is present.
Do not activate the speed control on the hand grip unless you are on the
electric motor bike 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.

Warranty Information ........................................................................13
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 motor bike.
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 motor bike 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 ride 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 motor bike 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). A helmet may be legally required by local
law or regulation in your area. Elbow pads and kneepads, a long-sleeved shirt,
long pants and gloves are recommended. Always wear athletic shoes (lace-up
shoes with rubber soles), never ride 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 motor bike 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.
Use caution when charging.
The charger is not a toy. Charger should be operated by an adult.
Do not operate charger near flammable materials.
Unplug charger and disconnect from bike when not in use.
Always disconnect from the charger prior to wiping down and cleaning your
scooter 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.

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 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.
MAKE SURE POWER SWITCH IS TURNED “OFF” BEFORE CONDUCTING ANY
MAINTENANCE PROCEDURES.

ASSEMBLY AND SET-UP
q Inflating the Tires
Tires are inflated when shipped, but they invariably lose some pressure between the point of
manufacturing and your purchase.
Using a bicycle tire pump equipped for a Schrader valve, inflate both tires to the PSI indicated on the
sidewall of the tire.
BEFORE RIDING
q Charging the Battery
Your electric motorbike may not have a fully charged battery; you must charge the battery prior to use.
•Initialchargetime:12hours
•Rechargetime:upto12hours,
depending on level of depletion.
•Fullychargebatterybeforestoring.
•Whenthemotorbikeisnotinregularuse,
recharge the battery at least once a
month until normal use is resumed.
Charger
•Runtime:Upto30minutesofcontinuousridetime.
Run time may vary depending on riding conditions,
climate and/or proper maintenance.
•Averagebatterylife:250charge/dischargecycles
•Toensurelongbatterylife,donotstorethebattery
in temperatures above 75° or below -10° F.
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.
WARNING:
Rechargeable batteries are
only to be charged under adult
supervision. Always disconnect
your electric motorbike from the
charger before cleaning with
liquid.
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.
Note: Make sure power is
turned OFF when unit is not in
use. If the power switch is left
on for an extended period of
time, the battery may reach a
stage at which it will no longer
hold a charge.
1 Plug the charger into a wall
outlet. If the lights on charger
do not light up, check the power
to the outlet. If necessary, try a
different outlet.
2 Turn power OFF before
charging. Plug the charger into
the charger port to charge unit.
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 overcharge protection to prevent
battery from being overcharged.
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.
WARNING: Failure
to recharge the battery at least
once a month may result in a
battery that will no longer hold
a charge.
