Abstract
A bicycle motor control apparatus includes a bicycle crank position detecting device, a bicycle crank position determining section, a stop determining section and a motor control section. The bicycle crank position detecting device detects a position of a bicycle crank. The bicycle crank position determining section determines if the bicycle crank is in a prescribed region including a bottom dead center position based on a detection result from the bicycle crank position detecting device. The stop determining section that determines a stopped state indicative of at least one a bicycle crank stopped state and a bicycle stopped state. The motor control section selectively outputs a motor driving command and stops the output of the motor driving command during a period in which the bicycle crank position determining section determines that the bicycle crank is in the prescribed region and the stop determining section determines that the stopped state exists.
