Abstract: A bicycle trainer, including a base, permitting fore and aft movement and a frame, supported by the base. Also, a seat and a handlebar assembly and a pedaling assembly is supported by the frame. The handlebar assembly is rotatably engaged to the frame, and is supported by a tongue, that is hinged to the base so as to permit horizontal rotation, and the handlebar assembly is attached to the tongue at a position removed from the hinge. Turning the handlebars causes the frame to move laterally.

Abstract: A bicycle rollers assembly (10) having a rear and a front and further having a rear pair of parallel rollers (12) each having an axis of rotation, and adapted to support a rear bicycle wheel having an axle parallel to the axes of rotation. The rollers (12) are spaced so as to support the rear bicycle wheel with the lowest part of the bicycle wheel positioned between the rollers. Also, a front support structure (18) supports a front bicycle fork support element (24) so as to permit horizontal rotation, and this support element includes a support (26) for each arm of a bicycle fork (29).

Abstract: A bicycle rollers device (110), having a frame (112, 114, 116) that includes a rear mounting assembly (112) for two rear rollers; a front mounting assembly for a front roller (114); support elements (140, 141, 142, 144, 145) for supporting the frame above a surface, upon which the support elements are set to rest; and a central bridge (116) connecting the front mounting assembly to the rear mounting gear. Also, two rear rollers are mounted in the rear mounting assembly and a front roller is mounted in the front mounting assembly and defines a roller width. Finally, the central bridge is more narrow than the roller width, thereby permitting a bicycle rider to mount and dismount a bicycle set on the rollers without encountering the central bridge.

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: A treadmill assembly that includes a frame and a treadmill belt. In addition, a sensor produces a signal representative of an aspect of the user's position relative to at least one point on the frame. A belt rotation assembly turns the belt with a speed related to the signal. In one preferred embodiment the speed of the belt is inversely proportional to the distance between the user and the front of the treadmill. In another preferred embodiment the treadmill is sized to support a cycle.

Abstract: A bicycle exercise assembly adapted to be mounted on a supporting surface includes a bicycle trainer device, adapted to operatively support an exercising person. Also, a relative motion-permitting assembly is adapted to be supported by the surface and to support the bicycle trainer device and to permit relative motion between the bicycle trainer device and the surface.
