A human powered reciprocal motion drive comprising: two independently driven drive assemblies for interchangeably operating in driving and return strokes, each drive assembly comprising: (a) a spiral cone; (b) a driving cable, a first end of the cable is connected to a first winding group on the spiral cone, and a second end of the same driving cable is connected to a second winding group on the same spiral cone; (c) a pedal which is attached to said driving cable; and (d) a gear assembly for defining a ratio between the number of revolutions in said first winding group and the number of revolutions in said second winding group, thereby to define an operative position along the thread of the spiral cone; the system further comprising a reciprocal motion mechanism which, during each driving motion by one of said pedals, causes a return motion of the other pedal.
