ABSTRACT:
An exercise cycle includes a frame having a front wheel assembly and handlebars. The front wheel assembly includes a fan wheel having side plates one of which has an intake port, and an intake assembly around the intake port, the intake assembly having openings which may be opened and closed. By opening and closing the intake openings, the resistance of the wheel to the air can be varied without changing the rotational rate of the wheel. The handlebars of the exercise cycle are pivotally connected to the cycle intermediate their ends. The lower ends of the handlebars are pivotally connected to a cam arm which is removably connected to the shaft to which the pedal is mounted. By connecting or disconnecting the cam arm to or from the pedal shaft, the handlebars can be selectively moved between a stationary mode and a mode in which the handlebars reciprocate between forward and backward positions.
