Alternating drive primarily for bicycles and similar driven vehicles, in which the rotation of driven pedals are converted into reciprocating swinging motion of swinging arms, and the swinging arms have respective driving arms (16, 16') coupled to a head portion (14, 14') surrounding the swinging shaft (11) of the pedals from which a traction arm (17, 17') is extending out that closes an angle with the driving arm and the remote ends of the driving and traction arms (16, 17) are interconnected by a connection arm (20, 20') A substantially triangular opening is formed between these arms, and the shaft of a driving wheel (15, 15') is positioned in this opening, the traction arm defines a traction path (19, 19'), and a flexible pulling rope (28) that rotates the driven wheel of the vehicle is led around at least one rope wheel (26) that has a shaft (35) guided and led along the traction path for adjusting the transmission ratio.
