A resistance generator adapted to a stationary bicycle exerciser to produce resistance when driven by cycling essentially comprised of a support unit, a transmission unit and a magnetism controlled unit; within, said magnetism controlled unit containing multiples of magnet arranged in circular being provided to a fixation disk and connected with an aluminum disk to a transmission shaft in the transmission unit; and resistance being produced by vortex magnetic loss resulted from those magnets positioned in relation to the rotating aluminum disk as driven by a wheel.
