A system for simulating bicycle riding which incorporates a conventionally-appearing bicycle physically maneuverable by a system user. Front and rear bicycle wheels are provided solely for visual authenticity. The simulating system provides electrical communication between mechanical maneuvering of the bicycle and a video display to visually reflect changes in speed and bicycle position on a variable-terrain track in response to pedaling, braking and steering changes by the user. Specifically, the system permits simultaneous lateral displacement and leaning of the bicycle away from the vertical plane to simulate travel about a curve. The system also permits rotation in a vertical plane about a pivot point proximate to the rear bicycle tire to simulate "wheelie" motion. These changes are monitored by sensors which transmit information to a computer which, in turn, correspondingly adjusts the position of an animated bicycle on the track using computer animation made possible by a unique bicycle model program. The computer considers the influence of the forces of nature on the bicycle and user. In addition, a computer-controlled motor simulates changing conditions of the track terrain, including downhill coasting by applying power assistance to bicyclist pedaling action. Finally, an audio system and a variable-speed air blower are provided, both interfaced with the computer to enhance riding simulation.
