Use and Maintenance of the battery
Your electric biccycle is equipped with a high quality battery, which has these advantages:
1) Low self discharge
2) Leak proof Structure
Make sure to fully charge your battery before the first usage, or after long usage. In case of
prolonged non usage, make sure to retrieve it from the electric bicycle and store it in a dry
place and make sure to charge it at least once a month to avoid crystallization of lead sulfates.
The battery could be charged on the electric bicycle or while removed from it. The original
charger which was provided has to be used, as the use of a different charger could irreparably
damage the battery.
Battery indicator:
The level indicated is actual when the electric bicycle is in motion. If the level is weak, make
sure to pedal and charge the battery as soon as possible.
Attention: do not touch the battery terminals with wet hands. Do not provoke a short circuit
with metal .That would surely cause accidents.
Use of the battery charger:
How to charge the battery:
1. Lift open the seat to access the battery
2. Disconnect the main power cable
3. Connect the exit of the charger onto the battery to charge
4. Connect the plug of the charger to an regular electrical socket
5. The red light is on while charging
6. The light will become green when the battery becomes fully charged
7. Unplug the plug of the charger from the socket, the exit of the charger from the
battery and reconnect the main power cable
Attention: 1. As usual the processes of charging are completed on the electric bicycle.
2. Remove the key from the ignition while charging the battery.
State of charge:
The charge, automaticaly controlled, stops as soon as the battery is fully charged and the red
light of the charger turns off.
Note: In case of need, the charging process could be interrupted before it is complete.
ATTENTION: During the battery charge, place the battery and the charger out of the reach
of children.
While riding or in storage make sure that water or metal particles don’t come in
contact with the charger .That could result in a short circuit
During the charging, the charger blows out some heat. Do not cover or put it next to
flammable materials. The charging process has to be in a dry and aired out place in order to
dissipate the heat. If the charger doesn’t stop charging after 10 hours, stop charging and call
customer service.
Use only the original charger.
Don’t leave the charger in the electric bicycle; it could be damaged by the vibrations of the
ATTENTION: In case the charger overheats (≥65°C), stop immediately the charging.
The motor and the power assisted wheel
The electric motor supplies more power, even with a slow rotation speed, it has better
efficiency, a lower sound level and longer autonomy.
To preserve the life span of your motor, it is recommended that a complete check up of
the electric bicycle be done.
ATTENTION: On a steep hill carrying a heavy load the motor could overheat and get stuck.
In this case, make sure to pedal so the motor gets freed from whatever was blocking it.
Don’t ride on a road where the water submerges more than a third of the power assisted wheel,
because water could penetrate into the motor and cause a malfunction to the motor.
