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.
