A driving unit and a battery-assisted bicycle include a stopping assist control without making a rider feel uncomfortable. The driving unit includes a crankshaft to which pedals are to be connected, a torque detector that detects a torque generated at the crankshaft, and an assist control stopping unit that stops an assist control based on an amplitude of a torque detected by the torque detector while the crankshaft rotates in a prescribed rotation angle range.
