A driving unit and a battery-assisted bicycle capable of accurately detecting a failure in each of a torque detector, a crank rotation detector, and a motor rotation detector is provided. The driving unit 40 includes a crankshaft 41 to which pedals 33 and 34 are to be connected, a motor rotation detector 68 that detects rotation of an electric motor 61, a torque detector 57 that detects a torque generated at the crankshaft 41, a crank rotation detector 58 that detects rotation of the crankshaft 41, and a sensor failure detector 106 that detects a failure in at least one of the motor rotation detector 68, the torque detector 57, and the crank rotation detector 58 based on detection results from the motor rotation detector 68, the torque detector 57, and the crank rotation detector 58.
