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 (K) 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 (K) in order to generate a torque (M motor ) for the drive of the electric bicycle , and • comparing the detected pedalling frequency (K) with a first threshold value (S1) and a second threshold value (S2), wherein ∘ when the first threshold value (S1) is reached or exceeded the control process reduces the torque (M motor ) of the electric motor , and ∘ when the second threshold value (S2) is reached or exceeded the control process increases the torque (M motor ) of the electric motor , and • comparing the detected pedalling frequency (K) with a third threshold value (S3) and a fourth threshold value (S4), wherein ∘ when the third threshold value (S3) 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 (S4) 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 (K) 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 (K) in order to generate a torque (M motor ) for the drive of the electric bicycle , and • comparing the detected pedalling frequency (K) with a first threshold value (S1) and a second threshold value (S2), wherein ∘ when the first threshold value (S1) is reached or exceeded the control process reduces the torque (M motor ) of the electric motor , and ∘ when the second threshold value (S2) is reached or exceeded the control process increases the torque (M motor ) of the electric motor , and ∘ when the first threshold value (S1) is reached or exceeded the control process reduces the torque (M motor ) of the electric motor , and ∘ when the second threshold value (S2) is reached or exceeded the control process increases the torque (M motor ) of the electric motor , and • comparing the detected pedalling frequency (K) with a third threshold value (S3) and a fourth threshold value (S4), wherein ∘ when the third threshold value (S3) 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 (S4) 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 (S3) 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 (S4) is reached or exceeded a shifting process of the electronically controllable gearshift into a relatively high transmission ratio is carried out. <EOS>
