[0002] A bicycle, also known as a pedal bike or a bicycle, is usually a small two-wheeled vehicle on land. After a person rides on the bike and uses the pedals as power, it is a green and environmentally friendly means of transportation.
[0003] The front support bracket of a bicycle is a device used to park the bicycle. They are usually designed to be able to firmly support the bicycle, facilitating users to park and saving space. The existing front support mechanisms for bicycles usually have relatively fixed specifications, and most of the different bicycle wheels are different. Therefore, the fixed-structure front support mechanism cannot adapt to most bicycles of different specifications during use. Moreover, most of the existing front support mechanisms can only perform bottom positioning of the wheel hub. Therefore, the stability is poor after positioning. For this reason, we propose a front support mechanism for bicycles. Content of the Utility Model
