<p>The present invention is directed to a bicycle trainer (18) that permits a bicycle to be used for stationary riding. The bicycle trainer has a modular fluid resistance unit (19) wherein resistance is provided by the rotation of an impeller (23) against a fluid contained in a sealed housing (21, 22). The resistance unit provides selectively variable resistance, is quiet to use, and simulates bicycle riding on a road.</p> |
