WARNING: Riding an electric motor bike does present potential risks
and caution is required. Like any riding product, an electric motor bike has inherent
hazards associated with its use (for example, falling off or riding it into a hazardous
situation). Like any riding product, electric motor bikes 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. USE EXTREME CAUTION.
WARNING: PARENTAL AND ADULT RESPONSIBILITY AND
SUPERVISION NECESSARY: 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 these products.
Razor 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.
WARNING: THE SX500/MX500 IS NOT FOR CHILDREN UNDER
AGE 14 OR HEAVIER THAN 175 LB (79 KG). THE MX650 IS NOT FOR
CHILDREN UNDER AGE 16 OR HEAVIER THAN 220 LB (100 KG).
Because products, like electric motor bikes, can and do present potential hazards
plainly associated with their use, it is well recognized THE NEED FOR 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 rider to cope with the hazards.
Razor recommends that children under the age of 14 not be permitted to use the
SX500/MX500 and that children under the age of 16 not be permitted to use the
MX650. This recommendation is based not just on age or weight or height – it
reflects consideration of expected maturity and skills as well as physical size. The
recommended rider age of 14 years or older for SX500/MX500 and rider age of
16 years or older for MX650 are only estimates and can be affected by the rider’s
size, weight or skills – not every child 14 years old will be suited to the SX500/
MX500 and not every child 16 years old will be suite to the MX650. Certainly, any
rider unable to fit comfortably on the SX500/MX500/MX650 should not attempt
to ride it, but a parent’s decision to allow his or her child to ride these
products should be based on the child’s maturity, skill, and ability to
follow rules. Razor emphasizes that adults are strongly advised not
to disregard Razor’s recommendations or permit younger children to
ride the SX500/MX500/MX650.
DO NOT EXCEED THE WEIGHT LIMIT OF 175 lb (79 kg) for SX500/MX500 and
220 lb (100 kg) for MX650. Rider weight alone also does not necessarily mean
a person’s size is appropriate to fit or maintain control of the SX500/MX500/
MX650. Keep these products away from small children and remember that
these products are intended for use only by persons who are, at a minimum,
completely comfortable and competent while operating these products.
Persons with any mental or physical conditions that may make them
susceptible to injury, impair their physical dexterity or mental capabilities
to recognize, understand, and follow safety instructions and to be able to
understand the hazards inherent in a product’s use, should not use or be
permitted to use products inappropriate for their abilities. Persons with heart
conditions, head, back or neck ailments (or prior surgeries to these areas of the
body), or pregnant women, should be cautioned not to operate these products.
CHECK AND MAINTAIN MOTOR BIKE CONDITIONS
Before use, check to confirm that any and all chain guards or other covers and
guards are in place and in serviceable condition. Check that the brakes are
functioning properly, and that tires are inflated properly and have sufficient tread
remaining. The motor bike should be maintained and repaired in accordance
with the manufacturer’s specifications, 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 motor bike 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 motor bike
and in a safe, outdoor environment suitable for riding.
The normal powered top speed of these motor bikes will be approximately 15
mph (24 km/h) for SX500/MX500 and 17 mph (27 km/h) for MX650, which can
be affected by conditions, such as rider weight, inclines, tire inflation and battery
charge level. Avoid excessive speeds that can be associated with downhill rides.
Maintain a hold on the handlebars at all times. Do not touch the brakes or motor
on your motor bike when in use or immediately after riding, as these parts can
become very hot.
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.
These electric motor bikes are 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 motor bike 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.
Do not attempt or do stunts or tricks on your electric motor bike. These motor bikes
are 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 motor bike.
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 drive train chain while the
motor is running.

Inflating the Tires
Tires are inflated when shipped, but they invariably lose some pressure between the point of manufacturing and your
purchase.
WARNING: Failing to
properly adjust and tighten the nuts
and bolts that affix the fork can cause
you to lose control and fall.
WARNING:
Do not over inflate, as this could
damage tire or wheel.
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 motor
bike 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.
1 Using a bicycle-style tire pump
equipped for a Schrader-type valve,
inflate the front tire to the correct PSI
indicated on the sidewall of the tire.

PRE-RIDE CHECKLIST
Brake
Check the brakes for proper function. When you squeeze the lever,
the brake should provide positive braking action. Make sure that
brakes are not rubbing when the lever is released.
Tires
Periodically inspect the tires for excess wear and regularly check the
tire pressure. Reinflate as necessary.
Frame, Fork and Handlebars
Check for cracks or broken connections. Although broken frames are
rare, it is possible for an aggressive rider to run into a curb or object,
and wreck and bend or break a frame. Get in the habit of inspecting
your motor bike on a regular basis.
Hardware/Loose Parts
Before every ride, check all parts, such as nuts, bolts, cables,
fasteners, etc., to ensure they are secure and assembled
correctly. There should not be any unusual rattles or sounds
from loose parts or broken components. If the unit is damaged,
do not ride. Reference “Safety Warnings” on page 1 of
this manual.
Safety Gear
Always wear proper protective gear, such as an approved safety helmet.
Elbow pads and kneepads are recommended. Always wear athletic
shoes (lace-up shoes with rubber soles) and keep shoelaces tied and
out of the way of the wheels, motor and drive system. NEVER RIDE
BAREFOOTED OR IN SANDALS.
Laws and Regulations
Always check and obey any local laws or regulations.

2If the brake has too much
slack, loosen the rear anchor
bolt with a 5 mm 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
37 mm and 44 mm.
3If the brake rotor is dragging on
the brake pads, use your fingers to
twist the caliper adjuster in either
direction until rotor is centered
between pads.
1To adjust brake cable 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.
WARNING: The brake is
capable of causing the electric motor
bike 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.
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.

razor.com. Please have the product I.D. code (located on the white label of your product) available for better assistance. Additional Customer Service contact information is
listed at the back of this manual.
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 using 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.
2Start 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
permanently damaging the wheel.
Spoke Tension
Chain and Sprocket
Proper chain alignment must be maintained. The wheel must not be skewed. If the chain is noisy or running rough, check the
lubrication, tension and alignment of the sprockets, in that order.
WARNING: Regularly check
the spoke tension and retighten
the spokes whenever loose. If you
have any doubt, ask an experienced
motorcycle or bicycle mechanic to
inspect your spokes to determine if the
spokes need tightening or adjusting.
WARNING: To avoid a pinch
or injury, keep fingers away from
moving sprockets and chain.
