PROBLEM TO BE SOLVED: To provide a bicycle with an electric motor in which, even in the state where generation of an auxiliary driving force by the electric motor is stopped, lighting of a light is possible and occurrence of the state where lights-out state of the light is maintained when circumference is dark such as night can be suppressed while resolving complexity of operation by a user.SOLUTION: A control part 100 is changed into a second state, when a light button is depressed in a first state where generation of an auxiliary driving force by an electric motor 160 is stopped and a light 170 is maintained in a lights-out state. The control part 100 in the second state performs lighting of the light based on a detection signal of an illuminance sensor 220 while generating an auxiliary driving force in the electric motor 160. The control part 100 is changed into a third state when a mode selection button is depressed in the first state. The control part 100 in the third state forcibly performs lighting of the light 170 while maintaining stop of generation of said auxiliary driving force by the electric motor 160. 【課題】モータによる補助駆動力の発生が停止している状態でもライトの点灯が可能であり、且つユーザによる操作の煩雑性を解消しつつ夜間等の周囲が暗い状況においてライトの消灯状態が維持されてしまう状況の発生を抑制する。【解決手段】制御部１００は、モータ１６０による補助駆動力の発生が停止され且つライト１７０が消灯状態を維持する第１の状態においてライトボタンが押下された場合には第２の状態に移行する。制御部１００は第２の状態においてモータ１６０に補助駆動力を発生させるとともに照度センサ２２０の検知信号に基づいてライトを点灯させる。制御部１００は、第１の状態においてモード選択ボタンが押下された場合には第３の状態に移行する。制御部１００は、第３の状態においてモータ１６０による補助駆動力の発生の停止を維持しつつライト１７０を強制的に点灯させる。【選択図】図２
