PROBLEM TO BE SOLVED: To provide a carrying expansion type bicycle capable of storing and carrying by downsizing easily in a short time for enabling a corporation between a public transportation system such as a train and bicycle using. SOLUTION: In order to achieve the above-described object, the frame of a bicycle is divided into a frame for rear wheel and a frame for front wheel, and by attaching and detaching of a pin of a lock mechanism provided in a fixed tube of the frame for rear wheel, a slide tube of the frame for front wheel telescopically slides in the fixed tube for rear wheel, thereby shorten the whole length of the bicycle. Moreover, each of the right and left pipe-shaped handles is divided into a root part and a grip part respectively, and the grip part pipe is made so as to telescopically slidable on the outer peripheral surface of the root part pipe, thereby respectively determining a handle length position during running and a handle length position when storing it. Further, the handle is pushed down and positioned by turning by 90 degrees in a lower limit position, thereby making the height of the handle smaller, and a pedal neck part is folded upward to cut down both of right and left pedal widths.
