The utility model provides a novel body-building bicycle. A manual middle axle is arranged in the middle part of a flat beam frame; a manual flywheel and a manual chain wheel are arranged at the two ends of the manual middle axle respectively; the manual chain wheel is connected with an additional chain wheel by a chain; a hand pulling chain is wound on the manual flywheel; the upper end of the hand pulling chain is turned by a turning wheel and is connected with a push-pull rod. According to the manual middle axle, a manner of matching pedals and hand pushing and pulling is adopted so that a double-power structure of a bicycle driver is realized; a flywheel disc is arranged between the middle axle and a pedal chain wheel to form a pedal flywheel wheel disc form, so that a unidirectional pushing structure is formed by the pedals and the pedal chain wheel; the fatigues of legs are convenient to relieve in a riding process; when the novel body-building bicycle is manually operated, the additional chain wheel and the pedal chain wheel are at a unidirectional pushing state so that the legs of a rider do not move front and back along the pedals, and furthermore, the inconvenience of manually riding is effectively solved. The novel body-building bicycle has a simple structure and is safe to ride, integrates body building and riding, and is suitable for popularization and application.
