Electric bicycles are not suitable for rough or steep roads. If encountering such a road, you should drive slowly or get off the car to push it. Driving on this type of road surface will result in poor working environment for motors, controllers, batteries, etc., which will reduce their service life and make them prone to damage.

When riding an electric bicycle, it is advisable to use manual or electric assistance, especially when driving uphill, under heavy loads, in the wind, or on rough roads. In this way, it can avoid long-term high current discharge of the battery, damage the battery, and improve the range of a single charge, extending the service life of the battery.

Before using an electric bicycle, the lubrication of the chain should be checked. Feel and observe whether the chain shaft rotates flexibly and whether the chain links are severely corroded. If the rust or rotation is not flexible, an appropriate amount of lubricating oil should be added, and in severe cases, the chain should be replaced.

Before using an electric bicycle, the tightness of the chain should be checked. Cycling with a chain that is too tight and pedals is laborious, while if it is too loose, it is prone to shaking and rubbing against other components. The sag of the chain is 1-2mm, which is more suitable. Generally, it can be adjusted appropriately when riding without pedals. When adjusting the chain, first loosen the rear wheel nuts, evenly screw in and out the left and right chain adjustment screws, adjust the tightness of the chain, and then tighten the rear wheel nuts again.
