Abstract:
A bicycle control apparatus is basically provided for controlling a bicycle having a drive assistance electric motor. The bicycle control apparatus includes a manual drive force detector, a rotational state detector and a controller. The manual drive force detector detects a manual drive force. The rotational state detector detects a rotational state of the crank. The controller issues a command for controlling a drive assistance force to be outputted by the drive assistance electric motor in accordance with the manual drive force detected by the manual drive force detector. The controller controls the drive assistance force to delay a reduction in the drive assistance force in relation to a reduction in the manual drive force upon determining the manual drive force is reduced, and controls the delay in the reduction of the drive assistance force in accordance with the rotational state of the crank.
