The device (1) for the motion transmission onto cycles comprises: a connecting core (2) able to be associated with a frame of a cycle in a rotatable way around an axis of rotation (3); and a ring gear (4) lying on a lying plane (11) surrounding the core (2) and able to be coupled to a flexible transmission element (5) closed on itself in a loop for starting said cycle along a direction of forward movement (6); oscillation means (10) placed between the connecting core (2) and the ring gear (4) and able to tilt the lying plane (11) with respect to the axis of rotation (3). |
