摘要

The pedal-driven vehicle comprises a wheel (1) that is equipped with the drive pedals (2a,2b). The drive pedals perform either free or forced opposite oscillations with the center of the pedal arms (3a,3b) that are arranged with a wheel hub (16). Another wheel is integrated on the axis of the driven front wheel. The drive pedals are arranged on freewheels of a common drive shaft (9) to function as the wheel hub drive.
