An exercise apparatus to which a bicycle may be attached for indoor training of cyclists. The apparatus includes a turntable rotatably mounted to a frame and a bicycle support device slidably connected to the frame for moving a bicycle along two axes in relation to the turntable. When a bicycle is mounted on the apparatus, the cyclist by turning the handlebars to the right or to the left in relation to the handlebars centered position, moves the support device forward or rearward and the contact point of the tire forward or rearward on the turntable. The first support becomes unstable in both the forward and rearward positions, moving the bicycle inwardly or outwardly, respectively, in relation to the turntable, increasing or decreasing, respectively, the moment arm of the force applied by the bicycle tire on the turntable as the bicycle is pedaled.

[ What is claimed:] [1.] An exercise apparatus for use in combination with at least a portion of a bicycle, that has a body, a front fork pivotally attached to the body, handlebars attached to the fork, a wheel attached to the body, and pedals operatively connected to the wheel, said apparatus comprising:a frame;a turntable rotatably connected to said frame;a base attached to said frame adjacent to said turntable for movement of said base along a first path between a first stop position and a second stop position;a carriage attached to said base for movement along a second path,a first support attached to said carriage, said first support being configured for attachment of at least a portion of a bicycle thereto so that when a bicycle is mounted on said first support a wheel of the bicycle is engagable with said turntable; andmeans for moving said carriage along said second path between a first unstable position and a second unstable position, and said first support being positionable at a stable position lying therebetween, whereby when the bicycle is mounted on said support with a wheel of the bicycle contacting said turntable and with said first support lying proximal said first unstable position, said base moves along said first path toward said first stop position, and when said first support lies proximal said stable position said base remains generally motionless, and when said first support lies proximal said second unstable position said base moves along said first path toward said second stop position.
