An electric bicycle drive unit for arrangement in a bottom bracket region of a bicycle frame, coaxially to the bottom bracket, is provided. The drive unit includes a torque sensor device for measuring a rider total torque. Rider total torque may include left-hand rider torque and a right-hand rider torque. The drive unit may include a bottom bracket shaft, an electric motor device arranged coaxially to the bottom bracket shaft, a hollow output shaft for transmitting a motor torque and the rider total torque to a bicycle drivetrain, and a rider moment coupling device for coupling the rider torque from the bottom bracket shaft to the hollow output shaft, and a motor torque coupling device for coupling the motor torque to the hollow output shaft. A torque measurement device is also provided.
