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
bike.
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.
