A crank-CVT transmission comprises a freewheel device (10), which is connected to an output shaft of the transmission. The freewheel device is adapted such that it selectively enables and blocks a relative rotation between the freewheel device and the output shaft. The crank-CVT transmission further comprises a switching unit (30) which is adapted to switch the freewheel device, and an internal shaft, which can be connected to the output shaft and by way of a connecting means to a differential. The internal shaft can be displaced in the axial direction of the output shaft. The crank-CVT transmission further comprises an actuator (20), which interacts with the switching unit and is adapted to initiate the switch of the freewheel device. The actuator comprises a first mechanism (100). The first mechanism is adapted to displace the internal shaft in the axial direction in order to disconnect the internal shaft from the differential (2). The actuator further comprises a second mechanism (200). The second mechanism is adapted to drive the switching unit. The second mechanism is coupled to the first mechanism and is driven after the first mechanism in terms of time.
