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.

After riding a new car for a period of time, the entire vehicle should be inspected and adjusted according to the instructions in the manual. Tightening and lubrication are essential at this time. Check if all fasteners are loose and if the transmission components are flexible. After lubricating the chain with oil, wipe off the floating oil and apply a little oil to the flywheel. Tire inflation should be appropriate, otherwise it will affect riding comfort and service life. The brake is a basic guarantee of safety and should be checked at any time. Any problems found should be adjusted or repaired immediately.
