SAFETY WARNINGS
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 IS NECESSARY: Because products, like electric scooters,
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 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.
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 scooter 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 such products.
DO NOT EXCEED THE WEIGHT LIMIT OF 120 lbs (54 kg).
Rider weight does not necessarily mean a person’s size
is appropriate to fit or maintain control of the scooter.
CHECK AND MAINTAIN SCOOTER 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 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, 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 3 mph before the motor will
engage.

Repair and Maintenance 5-6
Troubleshooting Guide 7
Electric Scooter Parts 8
The normal powered top speed of this scooter will be approximately
10 mph (16 kph), 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 scooter 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.
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.
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, chain while the motor is running.
Never use headphones or a cell phone when riding.
Never hitch a ride with a 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. 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 damp cloth.
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
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
ASSEMBLY OR MAINTENANCE PROCEDURES.
Estimated Assembly and Set-Up Time
Taomotor recommends assembly by an adult with
experience in bicycle mechanics.
Allow up to 10 minutes for assembly, not including initial
charge time.

Average battery life for a properly
maintained unit is approx. 250
charge/discharge cycles.
WARNING:
Rechargeable batteries are
only to be charged under adult
supervision. Always disconnect
your scooter from the charger
before cleaning with damp cloth.
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 may 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.

Inflating the Tire
The front tire is inflated when shipped, but it invariably may lose
some pressure between the point of manufacturing and your
purchase. Always inflate tire to the correct PSI before first time
use.
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.
When correctly tightened, the handlebars will not rotate out of
alignment with the front wheel under normal circumstances.
Note: The cable and wire assembly from the handlebar must
not wrap around the steering tube or handlebar. Sharp bends
or twisting of the brake cable can cause the brakes to
malfunction.
Note: The pressure 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 electric scooter 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.

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.
❑ 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 wall and wreck, bend or break a frame. Get
into the habit of inspecting your scooter on a regular
basis.
❑ Tires
Periodically inspect the tires for excess wear and regularly
check the front tire pressure. Re-inflate as necessary.
