The invention belongs to the technical field of bicycles, and relates to a treadle bicycle. The bicycle comprises a front wheel, a rear wheel, a directional handle head, a frame, a seat and treadles. The bicycle is characterized in that transverse hinge shafts are arranged at the left side and the right side of the front part of the frame; a left treadle and a right treadle are arranged on the left and right hinge shafts; arc-shaped racks (part of a gear) are arranged at the tail parts of the left and right treadles; the arc-shaped racks at the tail parts of the left and right treadles engage with flywheel at two sides of the rear wheel of the bicycle; springs are arranged on the left and right hinge shafts and can be used for automatically upwards tilting the tail parts of the left and right treadles. According to the technical scheme, the treadle bicycle has the advantages that a pressing power generated by a rider treading the left and right treadles of the bicycle can be directly transmitted to one-way flywheels at two sides of the rear wheel of the bicycle and then converted the power for moving forwards; the transmission of medium parts is saved, so that the structure is simple, and the kietic energy loss can be reduced.
