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.

Electric bicycles refer to transportation vehicles that use batteries as auxiliary energy on the basis of ordinary bicycles, and are equipped with control components such as motors, controllers, batteries, turnstiles, and display instrument systems.
