Abstract: A cycle exerciser having a one-way sprocket and a pair of one-way pinions disposed on a compound shaft. The one-way sprocket is rotated by a pedaling mechanism through a chain. The one-way pinions are respectively rotated by a pair of lever arms through a respective toothed element and a connecting mechanism. The toothed element engages and rotates the one-way pinion. The connecting mechanism comprises a substantially cylindrical swivel block and a torsional spring. The swivel block has a rim portion for fixedly securing to the toothed element and a protruding swivel shaft for telescopically receiving one end portion of the lever arm. The connecting mechanism, which is fixed to the toothed element by the rim portion thereof, connects to the lever arm in such a way that the lever arm can perform oscillatory and swiveling movement like rowing boats. The compound shaft is arranged to drive an energy absorbing wheel.
