WARNING
1.Check all parts of the bike and ensure that they are in good
condition before riding. If any problems are found, contact the
dealer immediately.
2.Obey traffic regulations and do not carry passengers on the bike.
3.Slow down in rainy, snowy, or slippery conditions and increase the
braking distance to ensure safety.
4.The bike is not designed for wading. If water level reaches the
wheel hub of the rear motor, it may cause a short circuit and
damage the electrical system.
5.Avoid touching the two metal contacts of the battery box at the
same time, as it may generate a large short-circuit current and lead
to an accident.
6.Do not disassemble or modify the bike's components by yourself. If
parts need to be replaced, purchase standard parts from the general
agency of the company.
7.Do not lend the electric bike to someone who cannot operate it
safely to avoid unnecessary damage and accidents.
8.To minimize the risk of serious injury, protective equipment should
be worn at all times including a helmet. You are responsible for your
own safety. Use this product with extreme caution and at your own
risk.

(Depends on load, terrain and riding habits)
Charging me: 6-8hours
Wheel diameter:20 inches
Charger: 48V2A
Baery instrucons
1.Baery charging:this car is an external lithium
baery,which can be removed for charging. When the
baery is low,open the key and take out the baery.Hold the baery ghely
with both hands to prevent it from falling,Take out the charger,plug the input
end into the power supply,and plug the output end dc2.1into the baery
charging hole,When the red lighe is on,it will be charged for 7-9 hours,and
when the green light is on,it will be full.
2.Warnings
(1).Load circuit may cause voltage and current,and the voltage orcurrent may
add to pack,the voltage orcurrent must be controlledas lower than RWV and
RWl,larger voltage or current may damage the PCM of pack.
(2).To prevent the possidility of the pack from leaking,heang fire.please
observe the following precauons:
Do not immerse the pack in water and seawater Guard against Damp.
Do not use and leave the pack near a heat source as fire or heater.
When recharging,use the baery charger specifically for that purpose.
Do not connect the pack to an electrical outlet.
Do not discard the pack in fire or heat it.

6
Do not short-circuit the pack by directly connecng the posive and
negave terminal with metal object such wire
Do not transport and store the baery together with metal objects such
as necklaces,hairpins etc.
Do not strike or throw the pack.
Do not directly solder the pack or baery and pierce the baery with a
nail or other sharp object.
As installed safety device in the baery,please do not resolve or chane
any other secons of the baery to protect the inherent safety funcons.
3.Cauons
(1).Do not use or leave the pack at very high temperature (for example at
strong direct sunlighe or a vehicle in extremely hot condions).
(2).Donot use it in a locaon where stac electricity is great,otherwise the
safety devices in the pack may be damaged,which will cause hidden trouble
of safety.
(3).If the pack leaks and the electrolyte get into the eyes,do not rub eyes,
instead,rinse the eyes,with clean running water,and immediately seek
medical aenon.Otherwise,eye injury can result.
(4).If the baery emits peculiar smell,heang,discoloraon,deformaon
during use or storage,or any abnormal phenomenon occurs during charging,
immediately remove the baery from the charger or device,and stop using
the primary charge and discharge to acvate the baery.
(5).In case the pack terminals art dirt,clean the terminals with a dry cloth
before use.Otherwise power failure or charge failure may occur due to the
poor connecon with the instrument.
(6).Be aware discharged baery may cause fire or smoke,tape the terminals
to insulate them.
(7).The pack should be stored at room temperature,charged to about40% to
60% of capacity.ln case of over-discharge,pack should be charged for one
me every 3 months while storing and baeries should be discharge and
charge aer being stored more than a year in order to acvate it and restore
energy.
(8).Prohibiteon short circuit
Never make short pack circuit.lt generates very high current which
causes heang of the cells and may cause electrolyte leakage,gassing
or explosion that are very dangerous.The LIP tabs may be easily short-
circuited by pung them.onconducve surface.Such outer short circuit
may lead to heat generaon and damage of the cell.

7
9.Mechanical shock
LIP cells have less mechanical endurance than metal-can-cased LIB.
Falling,hing,bending,etc.may cause degradaon of LIP characteriscs.
