An exercise device is described in which a flywheel fitted in a frame structure and rotated by a rider is provided with a brake mechanism for selectively braking the rotation of the flywheel, as desired. The brake mechanism comprises a copper strap fitted on the periphery of the flywheel and permanent magnet pieces attached to an arch pivotably mounted to the frame structure. The position of the arch is adjustable so that the distance of the magnet pieces from the copper strap varies in a predetermined manner to achieve a desired braking effect. To achieve a simple and clear display a two-arm lever is pivotably attached to the frame structure, the shorter arm of which being arranged to make contact with the arch and to follow the movements thereof. The end of the longer arm of the lever is arranged such that, when moved in response to movement of the shorter arm, acts as a basis for a display indicating the braking effect of the flywheel.

An exercise device comprising a flywheel fitted in a frame structure; means for rotating the flywheel; and a brake mechanism for selectively braking the rotation of the flywheel, the brake mechanism comprising a copper strap fitted on the periphery of the flywheel; permanent magnet pieces attached to an arch pivotably mounted in the frame structure; and means for adjusting the position of the arch so that the distance of the permanent magnet pieces from the copper strap varies in a predetermined manner to achieve a desired braking effect, said exercise device further comprising a two-arm lever which is pivotably attached to the frame structure, the shorter arm of the lever being arranged to make contact with the arch and to follow the movements of the arch, and the movement of the end of the longer arm of the lever being arranged to actuate a display indicating the braking effect of the flywheel.
