Patent ID: 7226395

Claim:
A virtual reality bicycle-training simulation platform that links the front wheel and rear wheel of a bicycle to a multimedia system, comprising: a steering unit that supports the front wheel of said bicycle, said steering unit comprising a rotary table, a wheel rim seat mounted on said rotary table for carrying the front wheel of said bicycle, two adjustment blocks respectively mounted on two distal ends of said wheel rim seat and movable relative to each other and lockable to said wheel rim seat for holding down the front wheel of said bicycle on said wheel rim seat, said adjustment blocks each having a top wheel rim bearing surface, and a steering sensor adapted to detect direction and amount of rotation of said rotary table upon biasing of the front wheel of said bicycle by a user and to output a signal to said multimedia system indicative of the direction and amount of rotation of said rotary table; and a rear wheel rack that supports the rear wheel of said bicycle, said rear wheel rack comprising a base frame, two rear wheel supports pivotally supported on said base frame and arranged in parallel, two coupling blocks respectively slidably coupled to said base frame at two opposite lateral sides, two struts coupled between said coupling blocks and said rear wheel supports, two locating members respectively and horizontally adjustably mounted on said rear wheel supports remote from said base frame and respectively coupled to the two distal ends of the wheel axle of the rear wheel of said bicycle to support the rear wheel of said bicycle on said rear wheel supports, and a damper controllable by said multimedia system to impart a damping resistance to the rear wheel of said bicycle.
