Method for controlling an electric drive motor of an electrically drivable bicycle

A method for controlling an electric drive motor of an electrically drivable bicycle comprising:

• determining a cadence of a rider of the bicycle;
• operating the electric drive motor under specification of (i) a first predefined target speed for the electric drive motor, which is lower than the determined cadence of the rider, and (ii) a first predefined torque for the electric drive motor, when the determined cadence of the rider exceeds a predefined cadence threshold value;
• operating the electric drive motor under specification of (i) a second predefined target speed for the electric drive motor, which is higher than the first predefined target speed, and (ii) a second predefined torque for the electric drive motor, when a rider torque exerted by the rider on a drive train of the bicycle exceeds a first predefined rider torque threshold value;
• and
• operating the electric drive motor under specification of a third predefined torque for the electric drive motor, when the rider torque exceeds a second predefined rider torque threshold value, which is higher than the first predefined rider torque threshold value,
• wherein a freewheel is configured to couple the electric drive motor to the drive train of the bicycle,
• wherein the first predefined torque and the second predefined torque are each maximum permissible torques and are set to provide substantially no drive support for the bicycle, and
• wherein the third predefined torque is a target torque and is set to provide a predefined drive support for the bicycle.
