Try not to use zero start (ie, start in place) for electric
bicycles, especially on load and uphill. When starting, you should
first use human power to ride, when it reaches a certain speed,
then turn to electric driving, or use electric power to drive
directly. This is because when starting, the motor must first
overcome the static friction force. At this time, the current is
large, close to or even reach the resistance current, so that the
battery can work at a high current and accelerate the damage of the
battery.
When using electric bicycles, try to use human-assisted or
electric-assisted methods, especially when going uphill, carrying
weights, windward or bumpy roads. In this way, it is possible to
avoid a large current discharge of the battery for a long time and
damage the battery, which is beneficial to increasing the mileage
of one charge and prolonging the service life of the battery.
Electric bicycles are not suitable for bumpy or steep roads. In the
case of such roads, you should drive slowly or get off the bus.
Driving under this kind of road surface, the working environment of
the motor, controller, battery, etc. is poor, which will reduce the
service life and be easily damaged.
