Abstract: PROBLEM TO BE SOLVED: To improve performance of torque measurement devices of a bicycle, a pedelec, or an e-bike comprising a free running wheel.SOLUTION: A freewheel hub 2 comprises a rotating hub shell 6 for carrying a free running wheel. Torque is transferred to the rotating hub shell 6 via a torque transmitting member 12. The applied torque is transmitted to magneto-elastically active regions R1, R2 including magnetically polarized regions, attached to a part of the torque transmitting member 12. The magnetic polarization becomes increasingly helically-shaped as the applied torque increases. A magneto-elastic sensor means has two pairs of magnetic field sensors S11, S12 and S21, S22 that are arranged proximate to the magneto-elastically active regions R1, R2 to generate signals corresponding to a torque-induced magnetic flux emanating from the magnetically polarized regions.SELECTED DRAWING: Figure 1
