[0002] The electric bicycle handlebar is the core component connecting the handlebar and the front fork, directly determines the comfort, control sensitivity and safety of the riding posture. Its angle design directly affects the handlebar height and horizontal inclination, and further adjusts the body center of gravity distribution of the rider. With the diversification of electric bicycle application scenarios (such as commuting, sports, cargo carrying, etc.), the demand for handlebar angle of different user groups (such as height difference population, long-distance riding enthusiasts) is significantly different. Although the existing high-end models can realize angle adjustment by replacing handlebars of different specifications, the process needs to disassemble and reinstall the components, which is cumbersome and difficult to adapt to dynamic riding requirements in real time.
[0003] Most of the electric bicycles on the market currently use fixed-angle integrated handlebars, which cannot be adjusted after installation, leading to the following problems:
