The utility model comprises wheels, a frame and a treading handle; a horizontal tube on the frame is provided with a handle shaft; the treading handle can swing surrounding the handle shaft; a fan-shaped internal gear is fixedly connected with the treading handle and is engaged with a flywheel. The utility model has the advantages of higher efficiency, large driving force, labour-saving ride, large travel speed range, self-regulated speed, no need of arranging a speed variator, short bicycle body, compact structure and convenient operation, maintenance and repair.
