A method for electronically controlling a bicycle gearshift (1) is described, comprising a support unit (3) configured to be mounted on a bicycle frame at an assembly of toothed wheels (RD) coaxial with one another of the gearshift (1) and a mobile unit (4) comprising a chain guide, said method comprising the steps of: - moving the mobile unit (4) with respect to the support unit (3) so as to impart onto the chain guide a primary displacement having at least a component in axial direction with respect to an axis (Z) of the assembly of toothed wheels (RD). It also comprises the step of: - moving the mobile unit (4) with respect to the support unit (3) so as to impart onto the chain guide a secondary displacement having at least a component in radial direction with respect to the axis (Z) of the assembly of toothed wheels (RD), wherein said step of moving the mobile unit (4) with respect to the support unit (3) so as to impart onto the chain guide a secondary displacement is carried out independently of said step of moving the mobile unit (4) with respect to the support unit (3) so as to impart onto the chain guide a primary displacement.
