before riding the scooter.
For your safety, please check whether the parts are in good
condition according to this User Manual before riding. Contact
your dealer in time in case of any problems.
Please follow the traffic laws. Slow down on slippery roads in bad
weather to allow greater braking distance for your safety.
Please pay attention to deep water. It may cause rusting or failure
of the motor, battery, or other parts if water level reaches wheel
axle.
Do not dismantle the scooter on your own. Please contact your
dealer for replacement or purchase of original parts.
For others' safety and preventing unnecessary damage to your
scooter, do not lend your scooter to those who can’t operate.
Please keep the User Manual properly.

Precautions

Rider and Passenger

This scooter is not designed for a ride of more than 2 persons.

Road Conditions
This scooter is not designed for off-road use.
This User Manual should be deemed as a permanent document
of This scooter. If this scooter is transferred to others, this User
Manual should also be handed over to the new owner.
Reproduction or reprint of any part of this User Manual is strictly
prohibited.

Warning: Failure to follow the instructions herein may lead to
serious casualties, personal injury, or scooter damage.

Attention: Do not exceed speed limit and apply brakes
cautiously. Always use side stand or central stand when parking.

Safety Notice

Using a helmet and protective goggles is strongly advised.
You are advised to take proper training or exercise before using on
open roads.
Please follow the Operation Guide (P.14) to fully understand how
to properly operate the scooter.
It should be noted that the braking distance in bad weather will
be much longer. Please avoid braking on paint markers, manhole
covers, and oil stains to prevent slipping. Pay extra attention when
riding through railway crossings, junctions, tunnels, and bridges.
Slow down if road conditions are unclear.
Do not use high beam indiscriminately. Continuous use of high
beam may disturb the vision of other drivers and pedestrians.
Do not use mobile phones or other electronic devices which may
draw your attention while riding.
Do not change the lane without signaling. Changing the lane at
will is one of the major causes for accidents. When you need to
change the lane, remember to switch on the Turn Signal Indicator
first. Always check the vehicles approaching from behind before
changing the lane.

Warning:

All operation should be strictly conform to the user manual. If
not, result will be assumed by user.
Must use original charger.
Pay attention to the type of battery and applied voltage. Mixture
use is forbidden.
Charging should be in ventilated environment. DO NOT charge in
closed space or under high temperature. DO NOT put charger into
trunk or tail box while charging.
While charging, connect battery with charger before connect with
electric supply. After fully charged, disconnect the electric supply
before unplug the battery plug.
When the green light turns on, disconnect the power in time.
Avoid long time connection between charger and AC power supply
while not charging.
While charging, if the signal light is abnormal, has odor, or the
charger is over temperature, please stop charging immediately
and check or change the charger in time.
When using and storing the charger, please avoid foreign matter,
especially water or other liquid in case of internal short circuit.
DO NOT bring charger within scooter, if have to, please make sure
of damping.
DO NOT disassemble or change the parts in charger by yourself.

24

25

Attention:

If the battery can not be fully charged after 12 hours, please
stop charging and contact your dealer.
To maximize the battery life, please keep the battery percentage
within 20% to 80%.
The battery will lose more capacity in lower temperature
conditions. To be more specific, the usable capacity at -10°C is
70%, 85% at 0°C, and 100% at 25°C.
The best battery capacity performance for storage is 50%.
Storing battery with less than 10% or more than 90% over a
long period of time will cause irreversible capacity loss to the
battery.

The battery needs to take out from the scooter for storage
longer than one week. In this condition, please keep the battery

at the temperature of 0°C to 20°C with capacity of 30%-70%. It's
advised to have at least one cycle of charge and discharge every
2 months to minimize battery capacity loss during storage.

If the battery failure is due to misuse or lack of proper
maintenance as instructed, its warranty will be invalidated.

Falling may cause uncontrollable internal damage to the battery
and may cause leakage, overheat, smoking, fire or explosion.

DOs and DON'Ts while Riding

Before Riding

Please check the following details before riding.

Check Point Description

Steering

Handlebar

1) Steadiness

2) Steering flexibility

3) No axial displacement or loosening

Braking 1) Braking lever has 5 to 9mm idle travel.

Tyres

1) The air pressure range of the front tyre is 20
to 25psi; the air pressure range of the rear tyre
is 26 to 32psi.

2) Proper tyre tread depth

3) No cracks or openings

Battery Adequate for planned distance to travel

Lights

Check all the lights—High Beam, Low Beam,
Brake Light, Turn Signal Indicator, etc.

Horn Check whether the horn can work.

26

Braking Precautions

Adjust the scooter upright before applying brakes. If the tyres
are locked and the scooter loses steering ability resulting from
excessive braking force, loosen the grip on the braking lever and
the tyres will be working again and the scooter will be stabilized.
Try to maintain a 1:1 ratio of front and rear braking force on
slippery roads.

Warning:

Using the front brake or rear brake only is dangerous because of
possible grip or control loss. Pay extra attention and use the brakes
gently when riding on damp, slippery roads, and around corners.
Otherwise, riders will be exposed to great danger.

Attention:

Inexperienced riders tend to use the rear brake only, which will
accelerate the wear of the brake and result in a longer braking distance.

Caution:

For your safety, do not exceed the speed limit, use the brakes gently to
maintain at safe speed while riding downhill.

27

DOs and DON'Ts while Riding

Maintenance and Repair

Users are advised to have the scooter checked and maintained on
a regular basis, even for the scooters that are not used for a long
time.

Regular Maintenance

Users are advised to have their scooters checked 2 months after
purchased or with 500 km travelled distance. Overall check
and maintenance is advised to be conducted every 6 months or
3000km thereafter.

Daily Maintenance

If any problem occurs during checks, please look through the
Home Repair Instructions or send the scooter to the dealer’s for
checks and maintenance.

Scooter Washing

Please always take out the battery before washing the scooter.
Please use neutral detergent and water to wash the scooter. Use
soft cloth to wipe the scooter after washing to prevent scratching.

28

Attention:

If the scooter is frequently used in overload, high-speed, bumpy
or up/downhill riding conditions, the maintenance cycle should
be shortened.
For more guaranteed quality and longer service life, please use
original parts, which are under normal warranty.

Warning:

If incapable of repair or adjustment on his/her own, the
scooter owner is advised to send the scooter to the dealer’s
for maintenance and adjustment for the sake of safety. Always
choose a smooth surface road for repair and adjustment and
unfold the central stand before repair and adjustment. If it’s
necessary to repair the scooter during a ride, mind the traffic.

Warning:

Do not use pressure washer to wash the scooter, especially
around the battery compartment. Do not flush the rear inner
mudguard, where the charger, controller and other parts are
installed behind. If the charging port on the scooter is wetted,
please do not charge before the charger dries off. Contacting
your dealer is recommended.

29

Maintenance and Repair

Short-term Storage:

Keep the scooter in flat, steady, well-ventilated and dry area.
Charge the battery to 50% full before storage to maximize battery
life.
Avoid exposure under sunlight and rain to reduce damage or
aging.

Long-term Storage:

Remember to have a charge and a discharge at least every 2
months and charge the battery to 50% full before storage to
maximize battery life.
Charge the battery to 100% full after long-term storage.
Check all the parts carefully to make sure that there is no
problem before riding it. If there's any problem, take the scooter
