Abstract
A two-stage resistance trainer is provided having a first magnet that is in proximity to a rotating wheel, and a moveable second magnet that is linked to the first magnet. The first magnet is moved when the rotating wheel rotates and the second magnet is moved closer to the rotating wheel to add a second order effect to the resistance. The trainer is capable of adjusting the first magnet position in relation to the rotating wheel to provide a different relationship of speed to resistance.
