In the first embodiment, the information on the power source is reported at predetermined time intervals, and in the first modification, the control unit is after the shift instruction is performed. 30e informs the user about the power source. In the first modification, when the shift instruction is made and the shift operation is completed, the user is notified of the information on the power source. In the following description, the same steps as those in the first embodiment are denoted by the same steps as those in the first embodiment, and the description thereof will be omitted.

In step S14 of Fig. 8, the control unit 30e determines whether or not the shift is completed after receiving the shift instruction output from the first operating member 18 (or the second operating member 20). When the shift instruction is manual shift, when any of the second lever member 36a (or 36b) and the third lever member 38a (or 38b) of the first operating member 18 (or the second operating member 20) is operated, control is performed. The portion 30e receives the shift instruction from the first operating member 18 (or the second operating member 20). The completion of the shifting is performed by the control unit 30e by the signal from the rear position sensor 46r of the electric rear derailleur 14 or the front position sensor 46f of the electric front derailleur 16. It is also possible to notify the information about the power source after a predetermined time elapses from the shift instruction (time corresponding to the shift completion time). When the completion of the shifting is received in step S14, the control unit 30e advances the processing from step S14 to step S5, and determines whether or not the voltage V is equal to or lower than the predetermined voltage Vs. The other processing is the same as steps S1 to S3 and steps S5 to S9 of the first embodiment.

The power consumed by the rear power source 44r and the front power source 44f is large at the time of shifting of the rear motor 42r and the front motor 42f. Therefore, by notifying the information on the rear power source 44r and the front power source 44f after receiving the shift instruction, it is possible to accurately grasp the information on the power source after the power consumption.

<Second Modification of First Embodiment>

In the second modification of the first embodiment, the control unit 30e notifies the information on the power source when the bicycle 10 is stopped, not at predetermined time intervals.

In step S24 of Fig. 9, the control unit 30e determines whether or not the bicycle 10 is stopped by the signal from the vehicle speed sensor 26a. When the control unit 30e determines that the bicycle 10 is stopped, the process proceeds from step S24 to step S5, and it is determined whether or not the voltage V is equal to or lower than the predetermined voltage Vs. The other processing is the same as that of the first embodiment, and thus the description thereof is omitted. In this case, when the user easily stops charging or replacing the power source, the remaining amount of the power source is displayed, so that it is easy to charge or replace the power source.

<Third Modification of First Embodiment>

In the first embodiment, the first modification, and the second modification, information on the power source is reported by using the display of the display 30b, and in the third modification, the buzzer 30c is used to notify the power source by sound. News. Then, in the third modification, the buzzer 30c is an example of a notifier and a sounding mechanism. In the third modification, at least one of the sounding interval, the pitch, and the volume of the buzzer 30c is changed in response to the information on the power source. In the tenth diagram of the third modification, the volume or pitch of the buzzer 30c can be changed depending on the voltage V. The structure of the display 30b of the bicycle computer 30 is substantially the same as that of the first embodiment, and the rear power source state display portion 31d and the front power source state display portion 31e are not provided. Alternatively, after the bicycle computer 30 is installed, the power source state display portion 31d and the front power source state display portion 31e can be used to display and voice information about the power source. Information.

In Fig. 10, in the third modification, steps S36 and S37 are different from steps S6 and S7 of Fig. 7. The other processing is the same as steps S1 to S5, step S8, and step S9 of the first embodiment. Therefore, the description of the other steps is omitted.

In step S36, when the control unit 30e determines that the received voltage V exceeds the predetermined voltage Vs, the control unit 30e causes the buzzer 30c to intermittently sound in response to the voltage V, and notifies the user of the information on the power source. For example, as the voltage V becomes lower, the sounding interval is made smaller. In step S37, when the control unit 30e determines that the received voltage V is equal to or lower than the predetermined voltage Vs, the buzzer 30c is continuously uttered in order to notify the user that the received voltage V is equal to or lower than the predetermined voltage Vs. Thereby, the user can notify the user of the necessity of replacement of the recommended power source 44r and the front power source 44f or the necessity of charging, and the user can easily grasp the information about the rear power source 44r or the front power source 44f. In this case, since the user is notified of the information about the power source by the sound, the information about the power source can be grasped even if the user does not see the display 30b.

<Second Embodiment>

In the second embodiment, the first control unit 52a controls the first display 54a, and the second control unit 52b controls the second display 54b. In the second embodiment, the information on the rear power source 44r is reported on the first display 54a by the display method, for example, and the information on the front power source 44f is reported on the second display 54b by, for example, the display mode. The bracket 32a and the bracket 32b are an example of a mounting portion. In the second embodiment, the first control unit 52a and the second control unit 52b are examples of the control unit.

In the eleventh diagram, the first control unit 52a and the second control unit 52b perform the notification operation in step S1, step S2, and step S4 to step S8 in Fig. 7 . Then, the voltage level of the rear power source 44r is displayed on the first display 54a at predetermined time intervals, and the voltage level of the front power source 44f is displayed on the second display 54b. Further, between the predetermined time intervals, the shift position of the electric rear derailleur 14 is displayed on the first display 54a, and the shift position of the electric front derailleur 16 is displayed on the second display 54b. Then, the first control unit 52a interactively displays the information on the rear power source 44r and the shift position of the electric rear derailleur 14 on the first display 54a at predetermined time intervals. Then, the second control unit 52b interactively displays the information on the front power source 44r and the shift position of the electric front derailleur 16 on the first display 54a at predetermined time intervals.

As described above, since the first display 54a is configured by a small-sized liquid crystal display having seven stages and two stages, the first embodiment does not ensure an area for displaying information of the rear power supply 44r (or the front power supply 44f). Therefore, in the second embodiment, as shown in Fig. 12, the degree of the voltage V is displayed as, for example, five stages by changing the display of the seven segments. When the voltage V is low At the predetermined voltage Vs (the lowermost display in FIG. 12), for example, "L" is displayed in three segments and blinks.

In the second embodiment, the first display unit 54a and the second display unit 54b can display information on the rear power source 44r of the first operating component, that is, the electric rear derailleur 14, and the second operating component, that is, the electric front derailleur. Information about the front power source 44f. Further, the first display 54a and the second display 54b are provided in an operation member that operates the operating component. Therefore, the user can easily grasp the information on the power source of the first operating component and the information about the power source of the second operating component without confusing the user.
