Abstract
The apparatus simulates a motorcycle ride over an irregular terrain and has a pair of cycles arranged at transversely opposite sides of the apparatus supported at the opposite ends of a common supporting structure. A horizontal rotatable drive member and a horizontal stationary member thereabove support the opposite ends of an upright gyrating motion transmitting member by ball and socket joint connections; the connection with the drive member being offset from the axis thereof and the connection through the stationary member being coincident with the axis of rotation of the drive member. The supporting structure is mounted on the upper end of the gyrating motion transmitting member and is guidably confined against rotation in a horizontal plane so that the opposite ends of the supporting structure are reciprocally movable in a substantially vertical elliptical path with compound vertical and tilting movement.
