Abstract:

A portable double folding bicycle, comprising: a front wheel, a frame assembly and a rear wheel, the frame comprising handlebars, a front frame, a crossbar assembly, a rear frame and a saddle, the handlebars being detachably connected to the upper end of the front frame, the crossbar assembly comprising a front crossbar, a middle crossbar and a rear crossbar, the rear end of the front crossbar and the front end of the middle crossbar being connected by means of a first folding piece, the rear end of the middle crossbar and the front end of the rear crossbar being connected by means of a second folding piece, the saddle being detachably connected to the rear crossbar, the inclination angle of the first folding piece is 58°-62°, and the inclination angle of the second folding piece is 89°-94°. The present invention provides the first folding piece and the second folding piece on the crossbar assembly, such that the handlebars can be inclined backwards after folding, enabling the front wheel and the rear wheel to sit coaxially, facilitating parallel towing; moreover, the handlebars and the saddle can be detached from the bicycle and placed into a backpack together with the folded bicycle, such that travel is better facilitated, thereby improving the usage of the bicycle as a whole.
