bearings with minimum friction. Overrunning clutch (3),
overrunning clutch (11) and the driving gear (43 are affixed to the
cylinder (2). Overrunning clutches (3) and (11) are affixed to the

the same direction. The overrunning clutches are connected with
pedals (7) and (10) by means of levers (9) and (6). Levers (9) and
(6) are connected by means of a cord in such a manner that
downward movement of one pedal results in upward movement of
the other pedal. This mechanism is situated behind the rear wheel
