controller 34 wirelessly receives the pairing signals PS21, PS22, PS11, and PS12 wirelessly transmitted from thetelescopic controller 73, thetelescopic controller 173, thefirst operating controller 24B, and thesecond operating controller 26B. Thecontroller 34 extracts the first identification information ID21, the second identification information ID22, the identification information ID11, and the identification information ID12 from the pairing signals PS21, PS22, PS11, and PS12. Thecontroller 34 compares the first identification information ID21, the second identification information ID22, the identification information ID11, and the identification information ID12 with the available device information AD1. The available device information AD1 includes a value indicative of the seatpost such as the bicycle electric seatpost assembly SP, a value indicative of the suspension such as the bicycle electric suspension FS, a value indicative of the right-hand side sifter such as thefirst operating device 24, and a value indicative of the left-hand side shifter such as thesecond operating device 26. Thus, thecontroller 34 stores the first identification information ID21, the second identification information ID22, the identification information ID11, and the identification information ID12 in thememory 34B. In the control mode, thecontroller 34 recognizes a wireless signal transmitted from a device paired with thecontroller 34 based on the first identification information ID21, the second identification information ID22, the identification information ID11, and the identification information ID12 stored in thememory 34B. However, thecontroller 34 does not respond to other wireless signals transmitted from other devices. For example, theindicator 44 quickly blinks when the pairing succeeded. - The
controller 34 wirelessly transmits a pairing completion signal PCS indicative of completion of the pairing to the bicycle electric seatpost assembly SP, the bicycle electric suspension FS, thefirst operating device 24, and thesecond operating device 26. Thetelescopic controller 73, thefirst operating controller 24B, and thesecond operating controller 26B wirelessly receive the pairing completion signal PCS and recognize that the pairing succeeded. For example, theindicators - The
controller 34 returns to the control mode when a time T1 is elapsed from sending of the pairing completion signal PCS. Thetelescopic controller 73 returns to the control mode after the specific time when the time T1 is elapsed after thetelescopic controller 73 wirelessly receives the pairing completion signal PCS. Thetelescopic controller 173 returns to the control mode from the paring signal transmission mode after the specific time when the time T1 is elapsed after thetelescopic controller 173 wirelessly receives the pairing completion signal PCS. Thefirst operating controller 24B returns to the control mode from the paring signal transmission mode when the time T1 is elapsed after thefirst operating controller 24B wirelessly receives the pairing completion signal PCS. Thesecond operating controller 26B returns to the control mode from the paring signal transmission mode when the time T1 is elapsed after thesecond operating controller 26B wirelessly receives the pairing completion signal PCS. For example, each of theindicators - The
controller 34 can be configured to keep the pairing mode for a preset time (e.g., 60 seconds) and to return to the control mode when the preset time is elapsed from a start of the pairing mode. Furthermore, thecontroller 34 can be configured to keep the pairing mode until the switch SW1 is pressed again. The same modifications can be applied to at least one of thetelescopic controllers - In the control mode after the pairing, the
controller 34 controls the bicycleelectric device 14 and other bicycle components based on a wireless signal including the first identification information ID21, a wireless signal including the second identification information ID22, a wireless signal including the identification information ID11, and a wireless signal including the identification information ID12. - The
controller 34 can be configured to wirelessly transmit the identification information ID3 of the bicycleelectric device 14 in the pairing mode. In such an embodiment, thetelescopic controller 73 can be configured to wirelessly receive identification information such as the identification information ID3 in the pairing signal transmission mode. Thetelescopic controller 73 can have a pairing mode which is different from the pairing signal transmission mode and in which thetelescopic controller 73 wirelessly receives identification information such as the identification information ID3. Similarly, thetelescopic controller 173 can be configured to wirelessly receive identification information such as the identification information ID3 in the pairing signal transmission mode. Thetelescopic controller 173 can have a pairing mode which is different from the pairing signal transmission mode and in which thetelescopic controller 173 wirelessly receives identification information such as the identification information ID3. - A bicycle
wireless control system 212 in accordance with a second embodiment will be described below referring toFIGS. 16 and 17 . The bicyclewireless control system 212 has the same structure and/or configuration as those of the bicyclewireless control system 12 except for the bicycleelectric device 14 and the bicycleelectric operating device 22. Thus, elements having substantially the same function as those in the first embodiment will be numbered the same here, and will not be described and/or illustrated again in detail here for the sake of brevity. - As seen in
FIGS. 16 and 17 , the bicyclewireless control system 212 comprises a bicycleelectric device 214, the at least one electrictelescopic apparatus 16, and a bicycleelectric operating device 222. Acontroller 234 of the bicycleelectric device 214 has substantially the same configuration as that of thecontroller 34 of the bicycleelectric device 14. For example, thecontroller 234 is configured to control theelectric actuator 28 to upshift in response to the first wireless signal WS11. Thecontroller 234 is configured to control theelectric actuator 28 to downshift in response to the second wireless signal WS12. - In this embodiment, as seen in
FIG. 17 , the bicycleelectric device 214 and the at least one electrictelescopic apparatus 16 synchronize in response to the operation signal WS1. Thecontroller 234 is configured to wirelessly transmit the control signal CS to the at least one electrictelescopic apparatus 16 based on the operation signal WS1 wirelessly transmitted from the bicycleelectric operating device 222. The firstelectrical switch 24A and the secondelectrical switch 26A are used for operating the at least one electric telescopic apparatus 16 (the bicycle electric seatpost assembly SP and the bicycle electric suspension FS). Thus, the first additionalelectrical switch 24G and the second additionalelectrical switch 26G are omitted from the bicycleelectric operating device 222. Thus, the bicycleelectric operating device 222 does not transmit the telescopic operation signal WS2. - The first control signal CS1 is transmitted from the
controller 234 to the first electric telescopic apparatus SP based on the operation signal WS1. The second control signal CS2 is transmitted from thecontroller 234 to the second electric telescopic apparatus FS based on the operation signal WS1. In this embodiment, thecontroller 234 is configured to wirelessly transmit the first control signal CS1 to the bicycle electric seatpost assembly SP based on one of the first wireless signal WS11 and the second wireless signal WS12. Thecontroller 234 is configured to wirelessly transmit the second control signal CS2 to the bicycle electric suspension FS based on one of the first wireless signal WS11 and the second wireless signal WS12. - In this embodiment, for example, the
controller 234 is configured to wirelessly transmit the first control signal CS1 to the bicycle electric seatpost assembly SP based on the second wireless signal WS12 and a current gear stage. Thecontroller 234 controls theelectric actuator 28 to downshift and wirelessly transmits the first control signal CS1 to the bicycle electric seatpost assembly SP in response to the second wireless signal WS12 (the downshift operation signal) when the current gear stage is within a specific gear range (e.g., from the second to sixth gear stages). The downshifting between the first and sixth gear stages is likely to occur when the bicycle runs on an upslope. Thus, the rider can adjust the height of the saddle BC3 (e.g., lower the saddle BC3) while the bicycle runs on the upslope. Furthermore, thecontroller 234 controls theelectric actuator 28 to upshift and wirelessly transmits the first control signal CS1 to the bicycle electric seatpost assembly SP in response to the first wireless signal WS11 (the upshift operation signal) when the current gear stage is within a specific gear range (e.g., from the ninth to eleventh gear stages). The upshifting between the ninth and twelfth gear stages is likely to occur when the bicycle runs on a downslope. Thus, the rider can adjust the height of the saddle BC3 (e.g., raise the saddle BC3) while the bicycle runs on the downslope. - Furthermore, the
controller 234 is configured to wirelessly transmit the second control signal CS2 to the bicycle electric suspension FS based on the second wireless signal WS12, the current gear stage, and a current lock position of the bicycle electric suspension FS. Thecontroller 234 controls the firstelectric actuator 28 to upshift or downshift and controls the secondelectric actuator 156 to keep the unlocked position of thepositioning structure 154 when the current gear stage changes within a specific gear range (e.g., between the seventh and twelfth gear stages). Thus, thecontroller 234 does not transmit the second control signal CS2 regardless of the first and second wireless signals WS11 and WS12 when the current gear stage changes between the seventh and twelfth gear stages in the unlocked state of the bicycle electric suspension FS. Thecontroller 234 controls the firstelectric actuator 28 to upshift or downshift and controls the secondelectric actuator 156 to keep the lockout position of thepositioning structure 154 when the current gear stage changes within a specific gear range (e.g., between the first and sixth gear stages). Thus, thecontroller 234 does not transmit the second control signal CS2 regardless of the first and second wireless signals WS11 and WS12 when the current gear stage changes between the first and sixth gear stages in the lockout state of the bicycle electric suspension FS. - The
controller 234 controls the firstelectric actuator 156 to downshift in response to the second wireless signal WS12 and controls the secondelectric actuator 156 to move thepositioning structure 164 from the unlocked position to the lockout position in response to the second control signal CS2 when the current gear stage changes from the seventh gear stage to the sixth gear stage. Thecontroller 234 controls the firstelectric actuator 156 to upshift in response to the first wireless signal WS11 and controls the secondelectric actuator 156 to move thepositioning structure 164 from the lockout position to the unlocked position in response to the second control signal CS2 when the current gear stage changes from the sixth gear stage to the seventh gear stage. Thus, shocks can be absorbed by the bicycle electric suspension FS when the bicycle runs on the downslope in the current gear stage is between the first and sixth gear stages. - A bicycle

The firstelectrical switch 24A and the second electrical switch 246A are omitted in the bicycleelectric operating device 322. - As seen in
FIG. 19 , theelectric actuator 56 of the bicycleelectric device 314 is configured to be operated in response to an operation of the bicycleelectric operating device 322. Thecontroller 73 has substantially the same configuration as that of thecontroller 34 of the first embodiment. In this embodiment, thecontroller 73 is configured to control theelectric actuator 56 to actuate theflow control part 62 between the closed position P11 and the open position P12 based on the telescopic operation signal WS2 (e.g., the first telescopic operation signal WS21) wirelessly transmitted from the bicycle electric operating device 322 (e.g., the first operating device 24). Thecontroller 73 is configured to wirelessly transmit the control signal CS to the at least one electrictelescopic apparatus 316 based on the telescopic operation signal WS2 wirelessly transmitted from the bicycleelectric operating device 322. Thecontroller 73 is configured to wirelessly transmit the control signal CS (e.g., the second control signal CS2) to the at least one electrictelescopic apparatus 316 based on the telescopic operation signal WS2 (e.g., the second telescopic operation signal WS22) wirelessly transmitted from the bicycle electric operating device 322 (e.g., the second operating device 26). - As seen in
FIG. 20 , the switch SW2 has substantially the same configuration as that of the switch SW1 of the first embodiment. Thecontroller 73 has a pairing mode in which thecontroller 73 receives the identification information ID22 of the at least one electrictelescopic apparatus 316. The switch SW2 is electrically connected to thecontroller 73 to set thecontroller 73 to the pairing mode based on the user input IP2 received by the switch SW2. Thus, the bicycle electric suspension FS is wirelessly operated through the bicycle electric seatpost assembly SP. - In a modification of this embodiment, the bicycle
electric device 314 can include the bicycle electric suspension FS instead of the bicycle electric seatpost assembly SP, and the at least one electrictelescopic apparatus 316 can include the bicycle electric seatpost assembly SP instead of the bicycle electric suspension FS. - As seen in a bicycle
wireless control system 412 illustrated inFIG. 21 , the bicycle electric suspension FS can be omitted from the bicyclewireless control system telescopic apparatus 16 or 216 includes the bicycle electric seatpost assembly SP. In such a modification of the bicyclewireless control system 12, for example, the second additionalelectrical switch 26G can be omitted from the bicycleelectric operating device 22. - As seen in a bicycle
wireless control system 512 illustrated inFIG. 22 , the bicycle electric seatpost assembly SP can be omitted from the bicyclewireless control system telescopic apparatus 16 or 216 includes the bicycle electric suspension FS. In such a modification of the bicyclewireless control system 12, for example, the first additionalelectrical switch 24G can be omitted from the bicycleelectric operating device 22. - As seen in a bicycle
