New type of description: [Technical field to which the new type belongs] The present invention relates to a notification device, and more particularly to a bicycle notification device that performs notification relating to the state of charge of the power storage unit of the bicycle. [Prior Art] In recent years, since various types of motor components such as a motor, a display device, and the like are mounted on a bicycle, a power storage unit is mounted on the bicycle. In such a bicycle, the remaining amount of electricity stored in the power storage unit is important to the rider. A technique for displaying the state of charge of the power storage unit mounted on the bicycle is known. (For example, Japanese Laid-Open Patent Publication No. Hei 01-59266). In the technique of displaying the state of charge of the conventional power storage unit, the state of charge of the power storage unit is determined based on a plurality of determination criteria: any one of the plurality of light-emitting elements is turned on/off according to the determination result, and the power storage is displayed step by step. status. B [New content] [New problem to be solved] In the conventional structure, the power storage state of the power storage unit cannot be known without actively watching the display. When the rider concentrates on cycling, the rider often misses the display of the power storage state of the power storage unit. The problem of the present invention is that the rider can easily recognize the state of charge of the power storage unit. [Means for Solving the Problem] M424288 The first novel bicycle notification device includes a detection unit, an operation unit, and a notification unit. The detecting unit detects the state of charge of the power storage unit. The operation unit is used to change the operating state of the bicycle motor parts. The notification unit performs a predetermined notification when the power storage state is in a predetermined state and the operation unit is operated. In the bicycle notification device, the notification unit is in a predetermined state, for example, in a state where the remaining amount of the power storage unit is small, when the operation unit is operated, a predetermined notification is performed. Here, by the rider. Since the operation of the operation unit notifies the state of charge, the rider can easily recognize the state of charge of the power storage unit. As a result, the system of the bicycle motor unit that supplies electric power by the power storage unit is less likely to suddenly stop. In the bicycle notification device of the second aspect, the bicycle notification device according to the first aspect is in a predetermined state in which the electric storage amount of the electric storage unit is lower than a predetermined amount.

When the power storage unit 12 is connected to the power storage unit 12, it is determined whether or not the power storage unit 12 is suitable for the power supply device 10. When it is suitable, the power storage unit 12 can supply power to each of the motor components. If it is not suitable, It is in a state in which electric power cannot be supplied from the power storage unit 12 to each of the motor components. Next, the control operation of the suspension system control unit 94 will be described with reference to the flowcharts shown in FIGS. 4 and 5. In the suspension system control processing, in step S1 shown in Fig. 4, it is judged whether or not the φ left first switch LSW1 is turned on. At step S2, it is judged whether or not the left second switch LSW2 is turned on. At step S3 shown in Fig. 5, it is judged whether or not the right first switch RSW1 is turned on.

At step -14 - M424288, step S16, it is judged whether or not the rear suspension system RS is in the locked state. When it has become the locked state, it moves to step S2. When it is not the locked state, that is, the free state, the process goes to step S17, the rear suspension system RS is switched to the locked state, and the process goes to step S2. When it is judged that the left second switch LSW2 has been turned on, that is, it has been operated, the process moves from step S2 to step S20. In the same manner as from step S10 to step S17, the switching operation of the rear suspension system RS from the state of φ is performed from step S20 to step S27. In step S22, it is judged whether or not the RS free control stop flag SF2 is turned on, and in step S23, the RS free control stop flag SF2 is turned on. In step S25, the RS free control stop flag SF2 is turned on, and in step S26, it is judged whether or not the rear suspension system RS is in a free state, and in step S27, the rear suspension system RS is switched to the free state. Steps S20, S21, and S24 are the same as steps S1 0, S11, and S1, and therefore the description thereof is omitted. When it is judged that the right first switch RSW 1 has been turned on, that is, it has been operated, the process moves from step S3 to step S30. In the same manner as from step S10 to step S17, the switching operation of the front suspension system Fs to the locked state is performed from step S30 to step S37B. In step S32, it is judged whether or not the FS lock control stop flag SF3 is turned on, and in step S33, the FS lock control stop flag SF3 is turned on. In step S35, the FS lock control stop flag SF3 is turned "on" in step S36, and it is judged whether or not the front suspension system FS is in the locked state". The front suspension system FS is switched to the locked state in step S37'. Steps S3 0 and S3 1 'S34 ' are the same as steps S 1 0, s 1 1 and S 1 4, and therefore the description thereof is omitted. When it is judged that the right second switch RSW2 has been turned on, that is, it has been operated, the process moves from step S4 to step S40. In the same manner as from step S10 to step S17, the switching operation of the front suspension system FS to the free state is performed from step S40 to step S47 • 15-M424288. In step S42, it is judged whether or not the FS free control stop flag SF4 is turned "on" in step S43' FS, the free control stop flag SF4 is turned on. In step S45', the FS free control stop flag SF4 is turned "on" in step S46, it is judged whether or not the front suspension system FS is in a free state", and the front suspension system is switched to the free state in step S47. Steps S40, S41, S44' It is the same as steps S10, S11, and S14, and the description thereof is omitted. Even if it is detected that the state of charge of the power storage unit 12 has reached a predetermined power storage state, the control pauses 'as long as the second command is given', the control according to the first command can be resumed. When it is detected that the state of charge of the power storage unit has reached a predetermined power storage state, the control of the motor component is suspended. Therefore, the rider can recognize the state of charge of the power storage unit. The state in which the control of the motor component is suspended is given. In the case of the second command, the control according to the first command can be resumed. Therefore, even if the power storage state is not immediately changed or the power storage unit is not immediately replaced after the power storage state is recognized, the motor component can be controlled as much as possible.
