CONTENTS
WARNING: Riding an electric scooter does present potential risks
and caution is required. Like any riding product, an electric scooter has
inherent hazards associated with its use (for example, falling off or riding it
into a hazardous situation). Like any riding product, electric scooters can and
are intended to move and it is therefore, of course, possible to lose control or
otherwise get into dangerous situations. Both children and adults responsible
for supervising them must recognize that, if such things occur, a rider can
be seriously injured or die, even when using safety equipment and other
precautions. RIDE AT YOUR OWN RISK AND USE COMMON SENSE.
WARNING: PARENTAL AND ADULT
RESPONSIBILTY AND SUPERVISION ISNECESSARY:
Because products like electric scooters can and do present potential hazards
plainly associated with their use, it is well recognized the THE NEED FOR THE
EXERCISE OF PARENTAL RESPONSIBILITY IN SELECTING RIDING PRODUCTS
APPROPRIATE TO THE AGE OF A CHILD, OR PARENTAL SUPERVISION IN
SITUATIONS IN WHICH CHILDREN OF VARIOUS AGES MAY HAVE ACCESS
TO THE SAME RIDING PRODUCTS, IS IMPORTANT. Not every product is
appropriate for every age or size of child and different age recommendations
are found within this category of product, which are intended to reflect the
nature of the hazards and the expected mental or physical ability, or both, of a
child to cope with the hazards.
The recommended rider age is 8 and older. Any rider unable to fit
comfortably on the scooter 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 it is
intended for use only by persons who are, at a minimum, completely
comfortable and competent while operating the scooter.
DO NOT EXCEED THE WEIGHT LIMIT OF 120lbs (54kg). Rider weight
does not necessarily mean a person’s size is appropriate to fit or
maintain control of the scooter. Person with any mental or physical
conditions that may make them susceptible to injury or impair their physical
dexterity or mental capabilities to recognize, understand, and follow safety
instructions and to be able to understand the hazards inherent in scooter
use should not use, or be permitted to use, products inappropriate for their
abilities.
CHECK AND MAINTAIN SCOOTER CONDITIONS
Before use, check to confirm that any and all chain guards or other covers or
guards are in place and in serviceable condition, that the brake is functioning
properly, and that tires are inflated properly and have sufficient tread
remaining. The scooter should be maintained and repaired in accordance with
the manufacturer’s specifications and using only the manufacturer’s authorized
replacement parts, and should not be modified from the manufacturer’s original
design and configuration.
ACCEPTABLE RIDING PRACTICES AND CONDITIONS
Always check and obey any local laws or regulations which may
affect the locations where the electric scooter may be used. Keep
safely away from cars and motor vehicle traffic at all times and only
use where allowed and with caution.
Do not activate the speed control on the hand grip unless you are on the
scooter and in a safe, outdoor environment suitable for riding. The electric
scooter must be moving at 3mph before the motor will engage.
Maintain a hold on the handlebars at all times. Do not touch the brakes or
motor on your scooter with fingers or bare hands when in use or immediately
after riding as these parts can become very hot.
Ride defensively. 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 electric scooter is intended for use on flat, dry surfaces such as
pavement or level ground without loose debris such as sand, leaves, rocks or
gravel. Wet, slick, bumpy, uneven or rough surfaces may impair traction and
contribute to possible accidents. Do not ride your scooter in mud, ice, puddles
or water. Watch out for potential obstacles that could catch your wheel or
force you to swerve suddenly or lose control. Avoid sharp bumps, drainage
grates, and sudden surface changes.
Avoid excessive speeds that can be associated with downhill rides.
Do not attempt or do stunts or tricks on your electric scooter. The scooter is
not made to withstand abuse from misuse such as jumping, curb grinding
or any other type of stunts. Racing, stunt riding, or other maneuvers also
enhance risk of loss of control, or may cause uncontrolled rider actions or
reactions.
Never allow more than one person at a time to ride the scooter.
Do not ride at night or when visibility is limited.
Never use near steps or swimming pools.
Do not allow hands, feet, hair, body parts, clothing, or similar articles to
come in contact with moving parts, wheels, or drivetrain, while the motor is
running.
Never use headphones or a cell phone when riding.
Never hitch a ride with another vehicle.
Do not ride your scooter in wet or icy weather and never immerse the scooter
in water, as the electrical and drive components could be damaged by water
or create other possibly unsafe conditions. Never risk damaging surfaces
such as carpet or flooring by use of an electric scooter indoors.
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 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 scooter should be regularly examined
for damage to the cord, plug, enclosure and other parts, and in the event of
such damage, the scooter 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 scooter when not in use.
Do not exceed charging time.
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.

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 scooter 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.
MAKE SURE POWER SWITCH IS TURNED “OFF” BEFORE CONDUCTING ANY
MAINTENANCE PROCEDURES.
Estimated Assembly and Set-Up Time
Razor recommends assembly by an adult with experience in bicycle mechanics.
Allow up to 10 minutes for assembly, not including initial charge time.
Allow up to 12 hours for charge (see page 3 for charging information).

ASSEMBLY AND SET-UP
q Attaching the Handlebars

prior to use.
2Turn power OFF before
charging. Plug the charger into
the charger port on the electric
scooter.

2With the front wheel pointed
straight ahead and the handlebars
square to the front wheel, tighten
the clamp as shown. Tighten
securely.
1 Loosen the collar clamp and
slide it upward. With a clock-wise
twisting motion, push and “thread”
the steering tube onto the fork until
it bottoms out on the fork headset
lock nut.
Note: Make sure any cables/
wires are out of the way before
inserting the stem into the fork.
WARNING: Failure
to recharge the battery at least
once a month may result in
a battery that will no longer
accept a charge.
WARNING: Always
disconnect your scooter 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.
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 protection to prevent
battery from being over-charged.
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.
q Attaching the Handlebar Grip WARNING: Failure to
properly engage the spring-loaded
button may cause the handlebar
to dislodge while riding and may
cause you to lose control and
fall. When correctly engaged, the
handlebar will not rotate nor will
it move sideways. Note that when
properly engaged, the spring-loaded
button is clearly visible in the hole
on the T-tube.
2Make certain the spring-loaded
button engages the hole and is
properly locked into the T-bar.
1Insert and secure the collaps-
ible handlebar by pressing the
spring-loaded button and
inserting it into the T-bar.
1Plug 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.
