When equipped with a handlebar and pedal force display subsystem, motion-generating subsystem, and visual subsystem, the interactive bicycle simulator can bring riders a realistic cycling feeling. In the interactive bicycle simulator, the most important component is the rider-bicycle dynamic model. The Newton-Euler method is adopted to formulate this model. Real-time data gathered by sensors and identified from a terrain database system are used for calculation of the rider-bicycle dynamics. Simple and effective devices are constructed and driven by the outputs of the rider-bicycle dynamic model. These devices are successfully applied to the interactive bicycle simulator.
