Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a detachable and foldable bicycle. Background Art

[0002] Bicycles are non-motorized vehicles. Bicycles are also called bicycles or bikes. They are usually small two-wheeled land vehicles. After people ride on the bicycles, they use pedals as power. They are green and environmentally friendly means of transportation. However, existing detachable and foldable bicycles have certain inconveniences when used.

[0003] A folding bicycle is disclosed in Chinese utility model patent application No.: CN202322828563.7. The handlebar can be flipped and folded toward the front wheel by a first folding bicycle joint, and the rear wheel can be flipped and folded toward the position of the front wheel by a second folding bicycle joint. The final form after folding is very compact and occupies a small volume. At the same time, after folding, the upper fixing belt and the lower fixing belt on the front folding beam are tied to the rear folding beam and fixed with Velcro fur surface and Velcro hook surface, which can improve the stability of the folded state. The folded bicycle will not loosen at will, which is convenient for carrying the folding bicycle. However, the folding bicycle needs to be carried and moved after folding, which is more laborious. In addition, the safety of the folding bicycle is average when riding or parking, and it does not have an alarm function when tipping over. In addition, the storage space of the folding bicycle is small when in use, which is not convenient for carrying items. For this reason, we propose a detachable and foldable bicycle.
