Problems solved by technology

[0002] The drive mechanism (sprocket drive mode) and the steering mechanism (handlebar and front fork mechanism) of the existing bicycle, that is, the human-powered bicycle, are installed independently of each other and operate independently without affecting each other. However, this limits the miniaturization of the car body. and storage, people have developed a variety of folding bicycles, but these bicycles are still driven by traditional pedals, which is only beneficial to the reduction of the car body, but still cannot reduce the car body to the most suitable for taking a bus or subway. The ideal volume, because taking a bus or subway requires a smaller car body, it is best not to exceed the space occupied by an adult standing or seat, otherwise it will affect the passage or standing or seat of the surrounding passengers

Abstract

The invention provides a simple bicycle. The simple bicycle comprises a front fork, a front wheel mounted at the lower end of the front fork, a flywheel drive assembly, a rear fork, a rear wheel mounted at the lower end of the rear fork, a handlebar mounting pipe mounted on the top of a front rotary shaft on the top of the front fork and a saddle mounting pipe for mounting a saddle. The saddle mounting pipe is mounted on the top of a rear rotary shaft on the top of the rear fork. The front rotary shaft and the rear rotary shaft are connected through a double-sleeve part. The double-sleeve partcomprises a front sleeve and a rear sleeve. The front rotary shaft is sleeved with the front sleeve, and the rear rotary shaft is sleeved with the rear sleeve. The simple bicycle further comprises alimiting mechanism for fixing the rear rotary shaft to be fixed relative to the rear sleeve. The simple bicycle is simple in structure, small in size after being folded, capable of being used as a faldstool and beneficial for relieving fatigue caused by long-time standing.

Description

technical field [0001] The invention belongs to the technical field of bicycles (human-powered bicycles), and in particular relates to a simple bicycle. Background technique [0002] The drive mechanism (sprocket drive mode) and the steering mechanism (handlebar and front fork mechanism) of the existing bicycle, that is, the human-powered bicycle, are installed independently of each other and operate independently without affecting each other. However, this limits the miniaturization of the car body. and storage, people have developed a variety of folding bicycles, but these bicycles are still driven by traditional pedals, which is only beneficial to the reduction of the car body, but still cannot reduce the car body to the most suitable for taking a bus or subway. The ideal volume is because taking a bus or subway requires a smaller car body, and it is best not to exceed the space occupied by an adult standing or seat, otherwise it will affect the passage or standing or sea...
