Abstract

A bottom bracket with a torque sensor unit. The bottom bracket has at least one pedal crank, a shaft that is non-rotatably connected to the at least one pedal crank, and a torque detection device for detecting a torque in the region of the shaft. The torque detection device has a first magnetization and a sensor which detects a change of the first magnetized due to a torque passed into the shaft. The bottom bracket allows a reliable and fast detection of torques, especially of the different torques of both pedal cranks. Utilizing the shaft, which is designed as a hollow shaft and the first magnetization, which is arranged on at least one section of the shaft.
