Abstract

A battery-assisted bicycle includes a driving unit that increases an assist ratio and provides a smooth assist control that does not make a rider feel uncomfortable. The driving unit includes a crankshaft to which pedals are to be connected, a crank rotation detector that detects rotation of the crankshaft, and an assist control stopping unit programmed to stop an assist control in response to the rotation of the crankshaft detected by the crank rotation detector.
