  • Cycle having unique balancing capabilities
    Patent number: 7762569
    Abstract: A cycle is disclosed that has at least one wheel with an axle rotatably mounted to a pair of opposing support plates. A seat is mounted to an upper end of an inverted Y-shaped seat support frame that includes two lower ends each pivotally mounted at a seat pivot to one of the support plates. A handlebar is mechanically coupled to each support plate with the handlebar being forward of the axle. In use, a user may balance on the cycle by manipulating the distance between the handlebar and the seat, facilitating the fine adjustment of the center of gravity of the cycle over the wheel.
