ABSTRACT:
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.
