ABSTRACT:
A cycle-type exceriser has a pedal shaft which drives an energy-absorbing wheel. A pair of oscillatable handlebar levers are connected by links to drive crank arms which are connected through one-way clutches to opposite ends of the pedal shaft. Oscillation of the drive crank arms by the handlebar levers rotates the pedal shaft to thereby drive the energy-absorbing wheel. A semi-recumbent embodiment has a seat and the pedal shaft at opposite ends, with the handlebar levers mounted therebetween and the energy-absorbing wheel below the seat. An upright embodiment has a saddle at one end, the handlebar levers and energy-absorbing wheel at the other end, with the pedal shaft therebetween. In the semi-recumbent and upright embodiments, the links are interconnected by an interlock lever constraining the handlebar levers to oscillation in opposite directions. The energy-absorbing wheel can be driven by the pedals only; by the handlebar levers only; or by both pedals and handlebar levers. A third embodiment eliminates the interlock lever and enables the handlebar levers to oscillate simultaneously in an optional "rowing" mode.
