Try not to use zero-start for electric bicycles, especially at load-bearing and uphill places. When starting, you should ride with human power first, and then switch to electric driving when it reaches a certain speed. Or use electric assisted driving directly. This is because when starting, the motor must first overcome the static friction. At this time, the current is large, close to or even reach the resistance current. This will cause the battery to work with high current and accelerate the damage of the battery.
When riding an electric bicycle, try to use manual or electric assistance. Especially when going uphill, carrying heavy loads, driving in the wind, or when the road is rough and uneven, you must use human riding to help. This can prevent the battery from discharging with high current for a long time and damaging the battery. It is beneficial to increase the continuous mileage of a charge and prolong the service life of the battery.
Electric bicycles are not suitable for rough roads or steep slopes. If you encounter such roads, you should drive slowly or get out of the car. When driving on this kind of road, the working environment of the motor, controller, battery, etc. will be poor, which will reduce the service life and be easily damaged.
