When the notification unit 72 includes the light emitting unit 72D, the notification unit 72 changes, for example, the lighting state of the light emitting unit 72D. The lighting state includes at least one of the number of light emitting elements to be lit, the type of lighting color of the light emitting element, and the blinking timing of the light emitting element. When the notification unit 72 includes the sound generation unit 72A, the notification unit 72 notifies the user of the failure of the component by, for example, a voice or a beep sound. When the notification unit 72 includes the vibration generation unit 72B, the notification unit 72 notifies the user of the failure of the component by vibration, for example.

The notification unit 72 may notify the user of information other than the movement of the human-powered vehicle 10 and the failure of the component. For example, the control unit 74 may include information on the state of the component, information on communication between the propulsion applying device 50 and another component, information on pairing between the propulsion applying device 50 and another component or an external terminal, and a battery unit 60. The information on the remaining battery level and the information on the assist mode by the motor 52A may be notified to the notification unit 72. For example, when the vehicle speed V of the human-powered vehicle 10 becomes the first vehicle speed V1 or higher and the motor 52A is stopped, the control unit 74 may notify the notification unit 72 of the stop of the motor 52A.

Since the notification unit 72 is provided in the propulsion force applying device 50, the user can grasp the information notified by the notification unit 72 without using, for example, a cycle computer and an external terminal.
