Abstract

An improved skating machine, wherein the improvement involves the incorporation of flexible components including (1) identical first and second pedal connector flexible bars rotatably connected at one respective one to a respective first and second longitudinal pedal bar and rotatably connected at their respective opposite end to a crank axle; (2) a resilient tension means connected at one end to the crank axle and connected at its opposite end to a post which is attached to a portion of a central longitudinal base frame; and (3) at least one transverse interconnecting elastic means transversely interconnecting the first and second longitudinal pedal bars. The flexible components have sufficient elasticity to prevent the machine from locking when the crank and the pedal connector bars are aligned with each other when the pedals are at their extreme left or right position.
