FIELD: transport.
SUBSTANCE: invention relates to drives with reciprocating feet levers and can be used in bicycles, bicycle cars, catamarans, etc. Drive comprises pedal axle (1) supporting the one-way motion transfer mechanisms and drive sprocket (2) interacting with driven sprocket (4) via endless chain (3). Cranks (5) and (7) with pedals (15) and (16) are fitted on bodies of one-way motion transfer mechanisms. Besides, this drive comprises reversing-synchronising shaft (9) with transfer links composed by sprockets or pulleys. Cranks interact via sections (12) and (13) of extra flexible member interacting with at least one adjusting roller (14). Crank locking device is composed of retainer-type (5, 7) limiters (19) and (20) or by overrunning clutch (25).
EFFECT: smaller muscle force to pedals, ruled out dead points, higher reliability and friendly use.
