Provided is a pedal engine bicycle (practical model) in which a power transmission method by a lever drive method of a pedal engine is made to drive the axle of the rear wheel by installing a lever rotation mechanism on an upper part of the front end without increasing the length of the bicycle, and, to this end, a method of improving the torque of the force by the leverage ratio of the basic model by reducing the diameter of the wheel is applied. A structure that allows installation of gears anywhere on the front and rear wheels in the future is provided.
