Abstract: Bicycle rollers that include a frame and front and rear rollers mounted in the frame, each having two lateral ends. Also, a pair of bumper/rollers are mounted on the frame adjacent both sides of the front roller. They are mounted so as to be horizontally rotatable, thereby acting to constrain a wheel of a bicycle supported by the front roller from moving laterally off the roller, while not stopping rotation of the bicycle wheel.

Abstract: An exercise stationary bicycle a base, a frame having a seat stay, a seat tube and a fork pivotally mounted on the base, and two hydraulic cylinders mounted between two sides of the fork and the base, whereby the frame may be swayed from side from side in riding thus making it to exactly simulate riding bicycles.

Abstract: The invention provides an apparatus for the training of cyclists that simulates the riding of a bicycle while in a stationary position. The training apparatus includes a running belt in a platform base on top of which are placed the wheels of a bicycle and a front vertical bar that secures the bicycle at the frame or handlebars onto the apparatus. The front vertical bar is adapted to pivotally swing laterally back and forth so that a rider of the bicycle may exert a force thereby tilting the bicycle to facilitate pedaling, and springs attached to the front vertical bar provide resistance against the inclination and return the bicycle to a generally vertical orientation. Stops are also provided to limit the degree of inclination of the bicycle.
