PURPOSE: A bicycle with bidirectional input and unidirectional output is provided to reduce injuries because of excessively using muscles and joints of users and to train muscle groups and joints relatively less used. CONSTITUTION: A bidirectional input and unidirectional output bicycle comprises a component and machine body(600), a manpower input device(11), a bidirectional input and unidirectional output electric device(13), a mechanical device, and a driving wheel set(15). The manpower input device comprises a pedal, a handle, a grip part, and a mechanical device. An input stage of the manpower input unit is driven by the kinetic energy of first and second driving rotation directions delivered from feet of human. The first and second driving rotation directions are in opposite direction. The bidirectional input and unidirectional output electric device is driven by the opposite rotation directional kinetic energies of the manpower input device, and outputs the kinetic energy having a fixed rotation direction. If an output stage is reversely driven by the opposite rotation direction, the bidirectional input and unidirectional output electric device prevents the bidirectional input and unidirectional output bicycle from being wound. |
