Abstract
A progressive resistance device is provided having a cylinder having an outer wall which defines an inner chamber. The cylinder is carried on an axle and is rotatable thereabout. An eccentric axle surrounds the axle and is rotatable relative the axle. A magnet carrier partially encircles the eccentric axle and carries a magnet. A bearing is nested between the magnet carrier and the eccentric axle. The magnet carrier is rotatable about the eccentric axle on an axis which is eccentric to the axle's axis, whereby the distance between the magnet and the outer wall is variable as defined by the rotative position of said housing relative said outer wall, which rotative position is governed by the speed of rotation of the cylinder. The progressive resistance device described herein is adapted for use as a roller on a bicycle trainer.
