The invention relates to a method for estimating a torque exerted on a pedal crank of an electric bicycle. The method provides for the detection of an angular velocity at which the pedal crank is driven, depending on the time. At least one signal property of the angular velocity is determined. The signal property is selected from the group consisting of the power of the AC component of the angular velocity, and the deviation of the signal shape of the AC component of the angular velocity from a sine curve which has the same frequency as the AC component of the angular velocity. Lastly, the torque is associated with the at least one determined signal property by means of a predetermined dependency between the at least one signal property and the associated torque. The invention further relates to an associated device and to an electronically retrievable memory which stores the link on which the association according to the invention is based. |
