Abstract
A cycle exerciser having a vaned wheel rotatably mounted on a frame and arranged to absorb energy by movement of the broad surfaces of the vanes against the surrounding body of air. Rotation of the wheel is effected through a pair of foot pedals and connected chain and sprocket mechanism, and/or through a pair of handle bars. Each handle bar is pivotally connected to the frame and is also connected to a respective eccentric through a crank ring rotatably mounted on that eccentric and a drive bar connected to both the crank ring and the handle bar. The two eccentrics are arranged 180.degree. out of phase and are connected to the foot pedal assembly so as to rotate in response to both pivotal movement of the handle bars and operation of the foot pedals. As the eccentrics are drivably connected to the vaned wheel, that wheel is caused to rotate in response to rotation of the eccentrics.
