PROBLEM TO BE SOLVED: To provide a foldable bicycle which has small width dimension (thickness) and bulk (vertical and horizontal dimension) in a folded state, and can be lightly carried on. SOLUTION: In the bicycle, the axles of a front and rear wheels are cantilevered by a frame directly or an exclusive fork member at the one side part, a disc wheel of one side wheel of either the front wheel or the rear wheel is formed so that the inner diameter of the rim is larger than the outer diameter of the tire of another wheel, and another wheel is formed in a recessed shape of storable depth. The frame is composed of a front frame supporting the front wheel and a rear frame supporting the rear wheel. The front frame and the rear frame are connected so that an axle of small diameter side wheel and an axle of large diameter side do not interfere with each other in a folded state, and the position where the small diameter side wheel is stored in a recessed shape part of the disc wheel of the large diameter side wheel, can be folded by approximate 180°with the folded shaft.
