Control method for an electric motor of an electric bicycle, at least comprising the steps • detecting a pedalling torque (M rider) of the cyclist, and • detecting the engaged transmission ratio (i) of the gearshift, • detecting a current pedalling frequency of the cyclist, and • controlling the electric motor as a function of the detected pedalling torque (M rider) and of the detected transmission ratio (i) and as a function of the detected pedalling frequency in order to generate a torque (M motor) for the drive of the electric bicycle, and • comparing the detected pedalling frequency with a first threshold value and a second threshold value, wherein ∘ when the first threshold value is reached or exceeded the control process reduces the torque (M motor) of the electric motor, and ∘ when the second threshold value is reached or exceeded the control process increases the torque (M motor) of the electric motor, and • comparing the detected pedalling frequency with a third threshold value and a fourth threshold value, wherein ∘ when the third threshold value is reached or exceeded a shifting process of an electronically controllable gearshift into a relatively low transmission ratio is carried out, and ∘ when the fourth threshold value is reached or exceeded a shifting process of the electronically controllable gearshift into a relatively high transmission ratio is carried out. • detecting a pedalling torque (M rider) of the cyclist, and • detecting the engaged transmission ratio (i) of the gearshift, • detecting a current pedalling frequency of the cyclist, and • controlling the electric motor as a function of the detected pedalling torque (M rider) and of the detected transmission ratio (i) and as a function of the detected pedalling frequency in order to generate a torque (M motor) for the drive of the electric bicycle, and • comparing the detected pedalling frequency with a first threshold value and a second threshold value, wherein ∘ when the first threshold value is reached or exceeded the control process reduces the torque (M motor) of the electric motor, and ∘ when the second threshold value is reached or exceeded the control process increases the torque (M motor) of the electric motor, and ∘ when the first threshold value is reached or exceeded the control process reduces the torque (M motor) of the electric motor, and ∘ when the second threshold value is reached or exceeded the control process increases the torque (M motor) of the electric motor, and • comparing the detected pedalling frequency with a third threshold value and a fourth threshold value, wherein ∘ when the third threshold value is reached or exceeded a shifting process of an electronically controllable gearshift into a relatively low transmission ratio is carried out, and ∘ when the fourth threshold value is reached or exceeded a shifting process of the electronically controllable gearshift into a relatively high transmission ratio is carried out. ∘ when the third threshold value is reached or exceeded a shifting process of an electronically controllable gearshift into a relatively low transmission ratio is carried out, and ∘ when the fourth threshold value is reached or exceeded a shifting process of the electronically controllable gearshift into a relatively high transmission ratio is carried out.
