Abstract: A method for operating a two-wheeler. The two-wheeler includes a drive unit and a sensor system, the sensor system including a rotation rate sensor, an acceleration sensor, and a wheel speed sensor. The wheel speed sensor detects at least one measuring pulse per revolution of a wheel of the two-wheeler. The method includes: detecting three-dimensional rotation rates of the two-wheeler, detecting acceleration values of the two-wheeler, and estimating a motion state of the two-wheeler based on the detected rotation rates, the motion state including estimated values for estimated acceleration values and an estimated speed and an estimated distance covered, first correction of the estimated motion state based on the detected acceleration values, ascertaining an instantaneous steering angle of the two-wheeler based on the corrected estimated motion state, and actuating the drive unit and/or an antilocking system of the two-wheeler as a function of the ascertained instantaneous steering angle.

Abstract: A method for determining a pedaling frequency of a bicycle, in particular an e-bike, includes (i) determining a movement signal representing a chronological progression of a locomotion of the bicycle, (ii) determining a frequency spectrum of the movement signal, and (iii) determining a pedaling frequency based on the determined frequency spectrum.

Abstract: An electrically propelled two-wheeled vehicle and a method for adjusting a drive torque of an electrically propelled two-wheeled vehicle. The electrically propelled two-wheeled vehicle includes: a sensor, based on which a pitch rate of the electrically propelled two-wheeled vehicle is ascertainable; a device for influencing a drive torque of the electrically propelled two-wheeled vehicle; and an evaluation unit configured to compare a pitch rate, which is ascertained on the basis of the sensor and represents a pitch rate of the electrically propelled two-wheeled vehicle relative to the surroundings of the two-wheeled vehicle, to a predefined, static pitch rate threshold value, and configured to reduce a drive torque acting upon a drive train of the electrically propelled two-wheeled vehicle using a predefined amplification factor, if a pitch rate generated by an upward movement of a front wheel of the electrically propelled two-wheeled vehicle exceeds the static pitch rate threshold value.
