Abstract
The present invention concerns a pedal cycle which is devised in such a way that, in order to improve on the fact that principally with unicycles the rider cannot easily mount, the space inside the hub is provided with a plurality of rollers for dividing up and receiving the weight transmitted to the frame at a downwardly widening angle rather than in the center of the wheel, and a geared drive force is transmitted to the wheel via a gear coupled to a pedal shaft passing through one end of the rollers.
