A method for controlling a motor of a derailleur of a bicycle electronic gearshift, and component suitable for carrying out such a method are disclosed. A method for controlling a motor of a derailleur of a bicycle electronic gearshift during a displacement from an initial position (A) towards a destination position (B) includes the step of feedback controlling (34, 210, 212, 214) of the current (I(t)) absorbed by the motor (12). A controller (24) of an electric motor of a derailleur of a bicycle electronic gearshift is configured to carry out a feedback control (34, 210, 212, 214) of the current (I(t)) absorbed by the motor during a displacement from an initial position (A) towards a destination position (B).
