Abstract: A controlled pressure resistance unit engagement system for bicycle training devices uses a clutch arrangement to limit the maximum torque applied. By doing so, a consistent, correct pressure on a bicycle tire by the resistance unit is achieved, thereby avoiding damage to the resistance unit and the bicycle tire and allowing a more consistent resistance unit power curve to be achieved.

Abstract: A bicycle trainer includes a frame and a resistance unit movably interconnected with the frame by an adjustment arrangement for movement through a range of operative positions and to an inoperative position. The adjustment arrangement includes an adjustment member that is selectively engaged with, and disengaged from, an engagement member. When disengaged, the adjustment member slides relative to the engagement member. The sliding movement of the adjustment member provides a first mode of operation to move the resistance unit to an initial engagement position adjacent the wheel, and the adjustment arrangement can be operated in a second mode of operation, such as by cam-type movement, to advance the resistance unit from the initial engagement position toward and against the wheel.
