Abstract

A portable foldable bicycle and a folding method therefor. The portable foldable bicycle comprises a front wheel assembly, a front fork assembly, a cross handle assembly, a cross beam assembly, a rear wheel assembly, a rear wheel support assembly, and a saddle assembly. The front fork assembly is disposed on the front wheel assembly. The rear wheel support assembly is disposed on the rear wheel assembly. The cross beam assembly, the cross handle assembly disposed on the front fork assembly, and the saddle assembly disposed on the rear wheel support assembly, as well as the a driving and transmission assembly and a brake assembly are disposed between the front fork assembly and the rear wheel support assembly. A plurality of X-shaped contract mechanisms is disposed, a front wheel is partially overlapped with a rear wheel, the cross beam assembly is partially overlapped with the wheels, ultrathin foldable pedals are disposed, and accordingly the foldable bicycle has a small size and a light weight, and is easy to carry; a front fork vertical pipe is disposed at the edge of the front wheel, the effective wheel base is increased after the bicycle is unfolded, and accordingly the riding is safer.

Description

technical field [0001] The invention relates to the technical field of bicycle structures, in particular to a portable folding bicycle and a folding method thereof. Background technique [0002] In the prior art, the folding method of the bicycle is unfavorable for carrying after the bicycle is folded, especially when taking a bus or subway. With the rapid development of today's economy, the rapid expansion of cities, and the increasingly serious problem of traffic congestion, cars are no longer the best means of transportation for citizens. Portable folding bicycles and buses or subways will become a new trend. In order to solve the problem of carrying a folded bicycle in the prior art, the inventor of the present application proposes a portable foldable bicycle based on years of research and experiments. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a portable folding bicycle and its f...
