PROBLEM TO BE SOLVED: To provide a folding bicycle whose volume becomes small after folding. SOLUTION: A folding joint part is provided on a beam. A rear fork is rotatably connected to a frame via a hinge shaft. The rear fork is installed on a support rod. The support rod is located at the side opposite to the frame. The beam is formed into an S shape. The hinge shaft is inclined against the frame at a sharp angle. When the bicycle is folded, a front wheel and a rear wheel are separately arranged so that each of them is arranged to the side of one end part of the beam or is stored inside a recess of the S-shaped beam. As a result, a bicycle width is reduced while reducing a bicycle size in the folded state. COPYRIGHT: (C)2007,JPO&INPIT
