Forever E-Bike china The chain should be checked for lubrication before use. Feel and observe whether the chain shaft of the chain rotates flexibly and whether the chain links are seriously corroded. If it is rusted or the rotation is not flexible, it should be filled with an appropriate amount of lubricating oil, and if it is serious, the chain should be replaced.

Before riding an electric bicycle, check the tire pressure, handlebar steering flexibility, front and rear wheel rotation flexibility, circuits, battery power, motor working conditions, and whether the lights, horns, fasteners, etc. meet the requirements for use.
(1) Insufficient tire pressure will increase the friction between the tire and the road surface, thereby shortening the mileage; it will also reduce the flexibility of the handlebar rotation, which will affect the comfort and safety of riding. When the air pressure is insufficient, the air pressure should be replenished in time. The tire pressure should follow the recommended air pressure in the "Electric Bicycle Instruction Manual" or the specified air pressure on the tire surface.
(2) When the handlebars are not flexible to rotate, stuck, stiff or tight, they should be lubricated or adjusted in time. Grease, calcium-based or lithium-based grease is generally used for lubrication; when adjusting, first loosen the lock nut of the front fork, rotate the upper gear of the front fork, and lock the lock nut of the front fork when the rotation flexibility of the handlebar meets the requirements.
(3) The rotation flexibility of the front and rear wheels is not good, which will increase the rotational friction and increase the power consumption, thereby reducing the mileage. Therefore, once a failure occurs, it should be lubricated and maintained in time. Grease, calcium-based or lithium-based grease is generally used for lubrication; if the shaft skin is faulty, you can replace the steel ball or shaft skin of Forever E-Bike china.
