Abstract: A motor for a bicycle includes a wheel axle, a hub housing, a bearing seat, and two through-holes, arranged in a housing cover next to each other in the circumferential direction with respect to the wheel axle, a driver configured to receive a torque applied by the operator of the bicycle by peddling and a driver through-hole, through which the wheel axle extends outside of the hub housing, a respective pin for each through-hole, said pin extending through one of the through-holes, a measuring disc arranged in the interior and outside of the bearing seat in a radial direction with respect to the wheel axle, a measuring disc through-hole, through which the wheel axle extends, and configured to receive the torque from the pins and transmit a torque to the hub housing, and a torque measuring device configured to determine the torque based on a deformation of the measuring disc.

Abstract: In an embodiment a bicycle wheel suspension includes a wheel axle having on its both axial ends a respective internal thread, a bicycle frame section of the bicycle, wherein the bicycle frame section comprises a first frame end and a second frame end, a respective bush for each one of the frame ends, wherein the respective bush is arranged concentrically with a through hole and form-fittedly in the through hole and a respective screw for each one of the frame ends, wherein the respective screw is arranged concentrically with the bush and extends form-fittedly through the bush and via the axial end to an inside of the wheel axle, and wherein a screw thread of the screw is in engagement with the internal thread.

Abstract: A wheel hub is disclosed. In an embodiment, the wheel hub includes a wheel axle, a clip encompassing an outer surface of the of the wheel axle in a C-shape manner and mounted torsionally rigid against the wheel axle, a magnetic field sensor mounted on the clip and a pole ring arranged concentrically around the wheel axle in a distance to the magnetic field sensor and supported such that the pole ring is rotatable relatively to the wheel axle, wherein the magnetic field sensor is configured to detect a magnetic field originating from the pole ring so that a movement of the pole ring relative to the wheel axle is deducible.

Abstract: A wheel hub transmission unit for a wheel hub defining an axis of rotation includes a pinion hub carrier arranged concentrically with respect to the axis of rotation and onto which a pinion is mounted torsionally rigid to drive the wheel hub, a hub body arranged axially next to the pinion hub carrier and having an interior space, a transmission sleeve arranged concentrically inside the interior space and including a magnetically coded material that forms a measuring portion, a drive coupling via which the pinion hub carrier and the transmission sleeve are coupled, and an output coupling via which the transmission sleeve is coupled to the hub body such that the torque is detectable in the interior space by the measuring portion of the transmission sleeve by the magnetic properties of the magnetically coded material, wherein the magnetic properties change under the influence of the torque.

Abstract: A wheel hub transmission unit for a drive wheel of a vehicle is provided. The wheel hub transmission unit includes a wheel axle, a pinion hub carrier concentrically arranged with respect to the wheel axle, a pinion mounted in a torsionally rigid manner onto said pinion hub carrier and configured to drive the drive wheel, and a torque transmission device having a transmission sleeve. The transmission sleeve is made from a magnetically coded material and includes a measuring area that is utilized to measure a torque by utilizing magnetic properties of the magnetically coded material of the transmission sleeve. An annular space is radially provided between the transmission sleeve and the wheel axle in the measuring area with a sensor coil being accommodated therein, the annular space being axially accessible from outside the transmission sleeve.
