Patent abstract
An exercise device, such as a bicycle or spinning bike, includes a frame, a first set of crank arms connected to a rotary shaft supported by the frame and having an imaginary rotational axis stationary with respect to the frame. A second set of crank arms is mounted eccentrically with respect to the rotational axis of the rotary shaft. A second shaft is coupled to the second set of crank arms such that rotation of the second shaft generates vibrations of the crank arms in the second set of crank arms.
