Apparatus that allows a sequential gear change to be made simply, immediately and reliably. It comprises an electric motor, served by gear controllers and by the relevant friction clutch, which moves a first wheel connected to a gear selecting arm; the selecting arm may be rotated in a series of angular positions corresponding to a series of transmissions and to a neutral gear position; a second wheel meshes with the first wheel so as to allow the latter a correct angular course equal to the angular movement of the selecting arm from one angular position to the next.<IMAGE>
