WIPO Patent Application WO/2011/122738

A1

The present invention relates to a folding bicycle, and more specifically to a folding bicycle which can be easily transported by reducing the overall size and volume of the bicycle by implementing a straightforward folding action and a simple external appearance. The folding bicycle of the present invention comprises: a support frame which is provided with a rotatable front wheel steered by operating handlebars on one side to the front, and which is provided with a saddle where a user can sit on one side in an upper part; a folding frame which is provided with a rear wheel rotatably coupled to one side, and which is foldably coupled, via a hinge part, to the side on a bottom part of the support frame; and a hinge part for coupling the support frame and folding frame while at the same time generating motive force during rotation of pedals provided on both sides, and, when the folding frame is folded, the folding frame comes to be spaced by a predetermined interval away from the support frame via the rotating action of the hinge part, thereby aligning the front wheel and the rear wheel.
