There is provided an electrically assisted bicycle capable of reducing unintended activation of a headlight caused by noise, in an arrangement that the headlight is turned ON based on an illumination detection result. An electrically assisted bicycle 10 includes a display/operation device 40 attached to the handlebar 32. The display/operation device 40 includes an operation surface 90; a light-receiving window 98 formed in the operation surface 90 for allowing ambient light to enter; and an illumination detection section 100 for detection of illumination in the surrounding environment based on the light from the light-receiving window 98. The controller turns ON the headlight 30 if the illumination detection section 100 gives a detection result of a value smaller than the first threshold value for a continued time period not shorter than the second threshold value. Also, the controller turns OFF the headlight 30 if the time period for which a detection result from the illumination detection section 100 exceeds the third threshold value continues for a time period not shorter than the fourth threshold value. The third threshold value is greater than the first threshold value. Preferably, the fourth threshold value is greater than the second threshold value.
