Abstract:
The Abdomicycle is a three or four-wheeled vehicle, (depending upon vehicle model) on which a rider sits upon a seat, leans back against a backrest which is provided for comfort and safety purposes and propels the vehicle either forward or reverse by a reciprocating motion on a bar that encloses them as they sit on the Abdomicycle. The bar is connected to either the single or dual rear wheels via a crank type mechanism that allows the linear pushing/pulling of the bar from front to back to be converted into a circular motion for the purpose of driving the rear wheel or wheels. The occupant's feet rest upon a forward steering linkage system that allows either foot pressure, or the leaning position of the occupant's body to turn the vehicle to the right or left. The vehicle includes a braking system connected by cable to the wheel(s) for the purpose of stopping the vehicle. The Abdomicycle is designed as a manually powered vehicle for exercises. However although it may defeat the purpose, motor or engine can be attached. Further more this system can apply to any vehicle such as ATV to stabilize turning.
