Two-stage exercise bike
 An exercise bike comprising two-stage of optional exercises wherein a clutch is provided between driving wheel and eccentric wheel. When clutch is engaged, the driving of pedals will cause the eccentric wheel to drive both saddle and handle in horizontally reciprocating swing in synchronously opposite directions or synchronously in the same direction with respect to each other through a set of connecting rods. In the meantime, the reciprocating swing action will enable two handle bars to make inward and outward movement with respect to each other, so that the user can vigorously exercise the whole body. It is especially suitable for strong youth. When clutch is disengaged, only a driven wheel produces action. This mode is suitable for old and aged men and women and children to exercise.
