A bicycle control apparatus is basically provided with a memory device and a control device. The control device is programmed with an automatic switching function and a manual switching function. The automatic switching function automatically switches an assist ratio, which is a ratio of a manual drive force to a drag force of an electric assist motor, based on a relationship between a threshold value that is stored and a reference value that is indicative of one of a bicycle traveling environment and a bicycle traveling state. The manual switching function switches the assist ratio based on a manual operation. The control device is further programmed to update the threshold value is updated based on the reference value when switching the assist ratio by the manual switching function.
