Abstract

The invention relates to a folding bicycle. The folding bicycle mainly comprises a bicycle front group, a bicycle frame group and a bicycle rear group, wherein the bicycle front group comprises a front wheel; the bicycle frame group comprises a first connecting rod, a positioning seat and a second connecting rod, the first connecting rod and the second connecting rod are rotatably pivoted to two ends of the positioning seat, and the bicycle frame group is connected with the bicycle front group through the first connecting rod and is connected with the bicycle rear group through the second connecting rod; the bicycle rear group comprises a tail frame and a rear wheel arranged on the tail frame; the bicycle rear group and the bicycle front group are folded respectively through the first connecting rod and the second connecting rod with the bicycle frame as a rotating pivot to form a side-by-side arrangement mode, and the axis of the rear wheel and the axis of the front wheel are coaxial. The folding bicycle can be folded to the minimum volume and is easy to carry due to the fact that the front wheel and the rear wheel can rotate simultaneously when the folding bicycle is pulled.

Description

technical field [0001] The invention relates to a folding bicycle, in particular to a folding bicycle. Background technique [0002] Common folding bicycles require various folding styles. The existing folding bicycles have a frame, and a front fork and a rear fork are respectively extended downwards at the front and rear ends of the frame. And the front fork and the rear fork are rotatably combined with a front wheel and a rear wheel respectively, and a faucet that can be folded and rotate the front wheel is combined above the front end of the vehicle frame. To adjust the stretchable and rotating seat, the vehicle frame is provided with a folding part on a horizontal bar, so that the folding bicycle can be folded with the folding part as the fulcrum, and the length of the folding bicycle can be adjusted according to the Folding and shortening makes the overall volume smaller and easy to store. [0003] The distance between the folded portion of the frame of the existing f...
