A motor actuated derailleur for a bicycle gearshift that has a support body adapted for mounting on a bicycle frame. A chain guide moves a bicycle chain between different engaged positions on respective gear wheels. A pair of connecting rods connects said chain guide to said support body with a first connecting rod of said pair of connecting rods being rotatable about a first rotation axis (X) at a first end thereof. A motor housed in said support body has an output shaft able to rotate about a second rotation axis. A transmission between said motor and said first connecting rod is housed in an inner chamber of said support body that comprises at least one adjustable end stop element that prevents the rotation of the output shaft beyond a predetermined rotation angle, in at least one of the two directions of rotation of the output shaft.
