Abstract
An exercise bicycle includes a frame assembly, a front wheel, a rear wheel, an intermediate shaft, two swing levers and two pedals. The front wheel is rotated by actuating the swing levers, while the rear wheel is rotated by actuating the pedals. The rotation of the front wheel and/or the rear wheel is transferred to the intermediate shaft. A resistance generating device includes a driving wheel sleeved rigidly on the intermediate wheel, a rotating shaft journalled on the frame assembly of the exercise bicycle, an input wheel sleeved rigidly on the rotating shaft, an endless driving element transferring the rotation of the driving wheel to the input wheel, a generator creating electric current when the rotating shaft rotates, and a resistance setting device connected to the generator. The resistance setting device adjusts the magnetic resistance of the generator to the rotation of the rotating shaft depending on the intensity of the current signal created by the generator. The higher the rotational speed of the rotating shaft, the greater the magnetic resistance to the rotation of the rotating shaft, thus increasing the exercise effect.
