PURPOSE: A foldable bicycle is provided to increase electric energy by increasing the torque of a pedal by an accelerating gear assembly. CONSTITUTION: A foldable bicycle comprises a front frame(10), a central frame(20), a saddle frame(30), a rear frame(40), and a hinge plate(60). A front wheel(11) and a handle unit(17) are mounted on a front frame. A pedal(23) is installed on the central frame. The saddle(31) is installed on the saddle frame. A rear wheel(41) is installed on the rear frame. The front and rear frames, the central frame and the saddle frame are coupled to the hinge plate, respectively. The hinge plates are successively coupled by a hinge shaft. The generator(21) of the central frame occurs electric energy in rotation of the pedal. The generator comprises a power generator unit an accelerating gear assembly.
