Abstract
A method for ascertaining a state of an electric drive of a transportation device, in particular a bicycle. The method includes: providing sensor data from sensors of the drive, the sensor data indicating parameters of the drive if an instantaneous operating range of the drive and/or of the transportation device corresponds to a predefined operating range; storing such sensor data, as measuring sensor signals, which originate from sensors predefined for the predefined operating range; and recognizing a defect of the drive if at least one of the measuring sensor signals deviates from a predefined standard sensor signal by a predefined degree; as well as outputting a warning about the presence of the defect to a user of the transportation device.
