Device and method for automatically shifting a gearshift mechanism of a bicycle

A device for automatically shifting a gearshift mechanism of an electric bicycle, comprising:

• at least one shifting actuator configured to automatically activate the gearshift mechanism;
• at least one computing unit connected to the at least one shifting actuator, an operator control and display unit connected to the at least one computing unit, at least one inclination angle sensor for detecting a current terrain inclination (ρ), and at least one further sensor for detecting a current velocity (v) of the bicycle, wherein the at least one inclination angle sensor and the at least one further sensor are connected to the at least one computing unit;
• wherein the operator control and display unit:
• makes available a first input apparatus for inputting a first input value (E1) in the form of a gear speed (n) of the gearshift mechanism for starting on a level underlying surface (F);
• makes available a second input apparatus for inputting a second input value (E2) in the form of a velocity (v) of the bicycle at which shifting into a maximum gear speed (n) of the gearshift mechanism takes place on a level underlying surface (F);
• has a third input apparatus for inputting a third input value (E3) in the form of a further velocity (v) of the bicycle at which shifting into a maximum gear speed (n) for this terrain inclination takes place on an underlying surface (F) with a positive terrain inclination (ρ);
• and
• wherein a shifting algorithm individualized on the basis of the first, second and third input values (E1, E2, E3) is stored in the at least one computing unit.
