  • Resistance device for bicycle trainers
    Patent number: 5611759
    Abstract: The present invention is directed to a bicycle trainer that permits a bicycle to be used for stationary riding. The bicycle trainer has a modular fluid resistance unit operates by the rotation of an impeller against a fluid contained inside a sealed housing. The resistance unit provides increasing resistance as the rotational speed of the impeller is increased, is quiet to use, and simulates bicycle riding on a road.
