The invention relates to a method for determining a speed of a single-track vehicle, in particular a pedelec or the like, comprising the steps of - determining a time profile of a magnetic field of a magnet arranged on a wheel of the vehicle in at least two, in particular three, spatial directions on the basis of measured values from a sensor arranged in a stationary manner in at least two, in particular three, sensor spatial directions, wherein the first of the at least two spatial directions corresponds to the direction of travel of the vehicle and the second of the at least two spatial directions corresponds to the vertical axis of the vehicle, - detecting an edge in the time profile of the magnetic field in one of the two spatial directions, preferably in the first spatial direction, by - determining high and low points in the time profile of the magnetic field, - determining a falling or rising edge on the basis of the time sequence of a high and low point, - comparing the amplitude of the determined edge with a threshold value, wherein the determined edge is considered to have been detected if the amplitude of the determined edge is greater than a first, lower threshold value and/or is greater than a second, greater adaptive threshold value, - determining the speed of the vehicle on the basis of at least two, in particular successive, detected edges.
