ABSTRACT:
A cycling mechanism consisting of foot pedals attached to rotatable cranks, in which the crank axes are independently connected to the machine frame in a movable manner such that in addition to each of cranks being rotatable about their respective axis, the crank axes are simultaneously allowed to translate to thereby cause the attached foot pedals to move in a combined revolving and axis translating manner. A flywheel or electric motor may be rotatably connected to the cranks to synchronize the cranks, and provide momentum characteristics. When used on an exercise machine, work may be performed to cause the pedals to rotate, or to cause the crank axis to translate.
