摘要：
A motorized bicycle gearshift (10) according to the invention comprises: a deformable articulated kinematic mechanism (20), intended to be fixed to a bicycle frame and capable of taking up different operating configurations; a chain guide (40), carried by the deformable articulated kinematic mechanism (20), capable of taking up different positions with respect to the bicycle frame according to the different operating configurations of the deformable articulated kinematic mechanism (20); a motor member (50), comprising a motor casing (51) and a master drive shaft (52) that projects directly from the motor casing (51), the motor member (50) being mounted on the deformable articulated kinematic mechanism (20) so as to deform it, thus making it take up the different operating configurations. The master drive shaft (52) is immobile in rotation and mobile in translation in the axial direction, with respect to the motor casing (51). This gearshift (10) provides greater precision in use, because the possible presence of dirt on the master drive shaft (52) does not hamper the movements thereof.
