AI Technical Summary
The front and rear double fork legs of traditional folding bicycles result in the folded width of the vehicle being too large, which cannot achieve the original design intention of reducing the floor size, making it inconvenient to carry.
The folding bicycle design adopts a front and rear single-arm misalignment setting. By setting on the left and right of the front fork, the folded bicycle space is minimized by using the single-arm space, and the position is limited by locks and clamps made of copper wire to improve connection stability.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figure 1-7, the present utility model provides a technical solution:
[0025] A folding bicycle with front and rear single arms arranged in a staggered manner, including a folding frame 1. A front fork 2 is fixedly connected to the left side of the front end of the folding frame 1. A connecting shaft two 9 is rotatably arranged at the bottom of the front fork 2. A front wheel 3 is fixedly connected to the connecting shaft two 9 through a nut one 10. A clamping member one is arranged on the connecting shaft two 9. By using the clamping member one, it is convenient to limit the nut one 10 and avoid the loosening of the nut one 10, thereby improving the connection stability of the front wheel 3.
[0026] A rear fork 6 is fixedly connected to the rear side of the rear end of the folding frame 1. A connecting shaft one 7 is rotatably arranged on the rear fork 6. A rear wheel 8 is fixedly connected to the connecting shaft one 7 through a nut two 14. A clamping member two is arranged on the connecting shaft one 7. By using the clamping member two, it is convenient to limit the nut two 14 and avoid the loosening of the nut two 14, thereby improving the connection stability of the rear wheel 8.
