Before using an electric bicycle, the height of the saddle and handlebar should be adjusted to ensure riding comfort and reduce fatigue. The height of the saddle and handlebar should vary from person to person. Generally, the height of the saddle is suitable for the rider to be able to land reliably on one foot (the whole vehicle should be basically upright), and the height of the handlebar is suitable for the rider to have their forearms flat and their shoulders and arms relaxed. But the adjustment of the saddle and handlebar should first ensure that the insertion depth of the pipe and the vertical pipe must be higher than the safety sign line.

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.
