The invention relates to a system for torque measurement, in particular at a drive of an e-bike, including at least one shaft which is rotatable about an axis, is magnetized in at least one axial partial section, and onto which a torque to be measured can be applied, at least one TMR sensor, which is situated outside the shaft and is designed for at least two-dimensionally, in particular three-dimensionally, measuring a magnetic field and which is arranged in relation to the at least one partial section in such a way that, when the shaft rotates about the axis, the at least one sensor measures a change of the magnetic field due to the magnetostrictive effect in the magnetized partial section when the torque acts on the shaft, and an evaluation unit, which is connected to the at least one TMR sensor and is designed for determining a torque acting on the shaft based on the measured values of the magnetic field.
