Abstract

A foldable compact bicycle is composed of frame with front tube, vertical tube and main tube unit consisting of two tubes A and B which are pinned at their middles, handle-bar, saddle and its supporting tube, front and back wheels, and a two-stage driver consisting of crank chain wheel and acceleration wheel for high speed.

Description

technical field [0001] The invention relates to a bicycle, especially a compact folding bicycle. Background technique [0002] In the prior art, folding bicycles are generally folded around the middle of the bicycle frame, and the two wheels are basically overlapped and parallel after folding. The bicycle folded in this way is actually inconvenient to carry. The reason is that because the wheels are generally larger, the volume after folding is still relatively large. If pulling or promoting, then this kind of folding bicycle is because of being subjected to the restriction of folding mode, and its pulling or pushing performance is relatively poor. Contents of the invention [0003] The purpose of the present invention is to provide a compact folding bicycle, which solves the problem of inconvenient pushing and carrying existing in the current folding bicycles. [0004] The technical scheme of the present invention is: a compact folding bicycle, comprising a front tube o...
