<p>The present invention mainly relates to a unicycle wherein a rider can not easily ride. To solve the problem, at first, for gravity structurally transmitted to a unicycle body to be divided and received in two or more points at a large angle under the center of a wheel, a plurality of rollers are installed inside a space of a hub. A wheel is rotated around the rollers as a central shaft to provide more advantageous condition for counterbalancing than a conventional unicycle wherein the center of gravity is transmitted to one central point. In the secured hub space, a rotational shaft of a pedal is put in front of the center of a wheel for the wheel to be effectively operated in a stable position compared to a conventional unicycle. Secondly, through a gear A (4) and a multiple gear coupled to a pedal shaft penetrating a hub (7) with a central shaft of a wheel and a partial disposition, a composition wherein a driving force having a different rotation ratio is transmitted to a gear / free wheel (6) in contact with the hub and another composition wherein a driving force of a pedal is directly transmitted to the gear / free wheel (6) may realize a mechanically converted structure in accordance with driving condition, thereby enabling efficient driving like a bicycle.</p> |
