Mock bicycle for exercise and training effects

An exercise apparatus comprising:

• a frame for supporting a user;
• first mechanical means, rotatably journaled to said frame, for being rotated by the feet of a user;
• velocity sensing means, coupled to said first mechanical means, for producing a first signal proportional to the angular velocity of the rotation of said first mechanical means;
• second mechanical means, rotatably journaled to said frame, for being manipulated between a first and a second position by the hands of the user;
• position sensing means, coupled to said second mechanical means, for producing a second signal indicative of the position of said second mechanical means;
• electronic simulation means, mounted to said frame and responsive to said first and second signals, for providing a changing visual scene simulating road conditions, said scene simulating inclines and declines in said simulated road conditions, the rate of change of said scene responsive to said first signal, the position of said scene with respect to said user responsive to said second signal;
• resistance control means, responsive to said simulated inclines and declines, for automatically applying a variable braking torque to said first mechanical means, wherein said resistance control means includes multi-pole A.C. synchronous induction motor means, mechanically coupled to said first mechanical means, for converting the rotational energy of said first mechanical means to electrical energy, said electrical energy being fed back to said motor means when said first mechanical means is rotated at an angular velocity exceeding the synchronous speed of said motor means, said motor means converting said fed back electrical energy to braking torque for braking said first mechanical means;
• and
• one-way transmission means for coupling braking torque produced by said motor means to said first mechanical means whenever said first mechanical means is rotated at an angular velocity exceeding the synchronous speed of said motor means, and for permitting said first mechanical means to freely rotate at a velocity less than the synchronous speed of said motor means.
