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.

What is claimed is: 1. A bicycle comprising: a. a front wheel and a front fork; b. a rear wheel including an axle; c. a pair of support plates, wherein each support plate having a forward side and a rear side, wherein the plates are connected to the axle; d. a main frame including a first connection and a second connection; e. wherein said first connection is pivotally connected to the front fork and said second connection connected to said axle; and f. a seat mounted to an upper end of an inverted Y-shaped seat support frame, the support frame including two lower ends each pivotally mounted at a seat pivot to one of the support plates at the rear side thereof. 2. The bicycle of claim 1 wherein a handlebar is coupled to the front fork for steering the bicycle. 3. The cycle of claim 1 further including at least one wheelie safety wheel rotationally captured at a rear end of a wheelie wheel support frame, a front end thereof fixed to the main frame. 4. The bicycle of claim 1 wherein the handlebar is pivotally fixed to an upper end of a handlebar post that terminates in the front fork at a lower end thereof, the handlebar being both rotatable in clockwise and counter-clockwise directions, and pivotable in forward and backward directions. 5. The bicycle of claim 1 wherein each seat pivot is an axle bolt. 6. The cycle of claim 1 wherein the seat support frame is telescopically and selectively adjustable in height. 7. The cycle of claim 4 further including a handlebar extension fixed to the handlebar and projecting downwardly therefrom to a lower end, the lower end pivotally connected to a forward end of a seat extension fixed to the seat support frame at a rear end thereof, such that when the handlebar is pulled back the seat support frame is pulled forward, and such that when the handlebar is pushed forward the seat support frame is pushed backward. 8. A cycle for a user to ride on a surface, said cycle comprising: a. least one wheel having an axle, the axle rotatably mounted on either side of the wheel to a pair of support plates, each support plate having a forward side and a rear side; b. a seat mounted to an upper end of an inverted Y-shaped seat support frame, the support frame including two lower ends each pivotally mounted at a seat pivot to one of the support plates between at the rear side thereof; c. a handlebar directly coupled to the forward side of the support plates and being forward of the axle; and d. wherein the user may balance the cycle by manipulating the distance between the handlebar and the seat while riding on the surface. 9. The cycle of claim 8, wherein the cycle is a unicycle. 10. The bicycle of claim 8 wherein said seat pivot is an axle bolt.
