1. A human powered reciprocal motion drive system, comprising:
a) two independently driven first and second drive assemblies for interchangeably operating in driving and return strokes, each drive assembly comprising:
b) only a single spiral cone including a single thread;
c) a single driving cable, a first end of the driving cable being connected to a first winding group on the spiral cone, and a second end of the same driving cable being connected to a second winding group, both said winding groups being disposed on said single thread of the same spiral cone;
d) a pedal which is attached to said driving cable; and
e) a gear assembly which is configured to define a ratio between the number of revolutions in said first winding group and the number of revolutions in said second winding group on the same cone, thereby to define an operative position along said thread of the spiral cone, and a respective torque that the cone applies,
wherein the system further comprising a reciprocal motion mechanism which is separate from any of the cones in said two drive assemblies, a first end of the reciprocal motion mechanism being in communication with said pedal of the first drive assembly and a second end of said reciprocal motion mechanism being in communication with the pedal of the second drive assembly, said reciprocal motion mechanism, during each driving motion by one of said pedals, causes a return motion of the other of said pedals to bring the pedal to an initial state, thereby to be ready for a next driving motion during a driving stroke of this specific drive assembly; and
wherein a portion of said driving cable, between the driving cable's two ends, turns around a driving roller.
