first identification information ID21. Thus, the telescopic
controller 73 is configured to recognize the first control signal
CS1 including the first identification information ID21 and to
ignore the second control signal CS2 free of the first
identification information ID21. The telescopic controller 73 is
configured to control the second electric actuator 56 in the

connected to the second electric actuator 56. The valve actuator
driver 76 is configured to control a rotational direction and a
rotational speed of the rotational shaft based on the valve
position and the first control signal CS1 wirelessly transmitted
from the controller 34. Furthermore, the valve actuator driver 76
is configured to stop rotation of the rotational shaft to position
the flow control part 62 at one of the closed position P11 and the
open position P12 based on the valve position and the first control
signal CS1 wirelessly transmitted from the controller 34.
The valve actuator driver 76 controls the second electric actuator
56 to keep the flow control part 62 at the closed position P11
while the valve actuator driver 76 does not receive the first
control signal CS1. The valve actuator driver 76 controls the
second electric actuator 56 to move the flow control part 62 from
the closed position P11 to the open position P12 when the valve
actuator driver 76 receives the first control signal CS1. The valve
actuator driver 76 controls the second electric actuator 56 to move
the flow control part 62 from the open position P12 to the closed
position P11 when the set time is elapsed.

detachable from the connecting structure CS30 in a state where the
latch CS33 is at the unlock position P42.
The connecting structure CS30 electrically connects the power
supply 182 to the electric positioning actuator 156 in the lock
state. The connecting structure CS30 includes a first electric
contact CS35. The power supply 182 includes a second electric
contact (an electric contact) 182C contactable with the first
electric contact CS35 in the lock state.
As seen in FIG. 10, the bicycle electric telescopic apparatus (the
bicycle electric suspension) FS further comprises a protecting
cover CS37 detachably attached to the connecting structure CS30 to
protect the power supply 182 in the lock state. For example, the

The connecting structure CS30 includes a first receiving recess
CS30B and a second receiving recess CS30C. The first pawl CS37B is
fitted in the first receiving recess CS30B to couple the protecting
cover CS37 to the connecting structure CS30. The second pawl CS37C
is fitted in the second receiving recess CS30C to couple the
protecting cover CS37 to the connecting structure CS30. The cover
body CS37A covers the power supply 46 in a state where the first
and second pawl CS37B and CS37C are fitted in the first and second
receiving recesses CS30B and CS30C. The protecting cover CS37 can
be omitted from the bicycle electric telescopic apparatus (the
bicycle electric suspension) FS.
As seen in FIG. 11, the bicycle electric telescopic apparatus (the
bicycle electric suspension) FS further comprises an additional
cover CS38 attachable to the connecting structure CS30 to cover the
connecting structure CS30 in a state where the power supply 182 is
detached from the connecting structure CS30. The additional cover

body CS38A is fitted in an accommodation opening CS3D to cover the
first electric contact CS35 of the connecting structure CS30 in a
state where the additional cover CS38 is attached to the connecting
structure CS30. The additional cover CS38 can be omitted from the
bicycle electric telescopic apparatus (the bicycle electric
suspension) FS.
As seen in FIG. 12, the bicycle power supply system PSS further
comprises a power supply cover CS39 configured to be detachably
attached to the power supply 182 in a state where the power supply
182 is detached from the electric component SP. The power supply
cover CS39 is configured to cover the electric contact CS36 in an
attachment state where the power supply cover CS39 is attached to
the power supply 182. The power supply cover CS39 includes a cover
body CS39A, an attachment opening CS39B, and an attachment pawl
CS39C. The cover body CS39A at least partly covers an attachment
surface 182D of the power supply 182 in a state where the power
supply cover CS39 is attached to the power supply 182. The
attachment pawl 182A is fitted in the attachment opening CS39B to

shown) to contact the second electrical contact 182C. The
indication circuit CS39E is electrically connected to the charged
state indicator CS39D to control an indication state of the charged
state indicator CS39D based on the sensing result of the charged
state or the non-charged state of the power supply 182. The charged
state indicator CS39D and the indication circuit CS39E can be
omitted from the power supply cover CS39.
As seen in FIGS. 5, 7, and 8, at least one of the first power
supply 46 and the second power supply 82 or 182 is configured to be
detachably and alternatively connected to the first connecting
structure CS10 and the second connecting structure CS20 or CS3. The
first power supply 82 is configured to be detachably connected to
the second connecting structure CS20 and/or CS3. The second power
supply 82 and/or 182 is configured to be detachably connected to
the first connecting structure CS10. However, the structure of the
first connecting structure CS10 can be different from the structure
of the second connecting structure CS20 and/or CS30. For example,
at least one of the first connecting structure CS10 and the second
connecting structures CS20 and CS30 can include a structure inside
which a power supply is accommodated.
As seen in FIG. 7, the bicycle electric telescopic apparatus (the
bicycle electric seatpost assembly) SP further comprises a manual
operating member M1 coupled to the positioning structure 54 to
manually actuate the positioning structure 54 without electricity
of the power supply 82. The manual operating member M1 is coupled
to the rotational shaft of the second electric actuator 56 and
includes a tool engagement part such as a hexagonal hole. The flow
control part 62 (FIG. 6) is manually moved relative to the first
tube 50 in the telescopic direction D1 by rotating the manual
operating member M1 with a tool such as a hexagonal wrench.
As seen in FIG. 8, the bicycle electric telescopic apparatus (the
bicycle electric suspension) FS further comprises a manual
operating member M2 coupled to the positioning structure 154 to
manually actuate the positioning structure 154 without electricity
of the power supply 82. The manual operating member M2 is
mechanically coupled to the positioning structure 154 and includes
a tool engagement part such as a hexagonal hole. The positioning
structure 154 (FIG. 6) is manually actuated between the lockout
position and the unlocked position by rotating the manual operating
member M2 with a tool such as a hexagonal wrench.
As seen in FIG. 15, the controller 34 enters the pairing mode when
the switch SW1 is pressed in the control mode of the bicycle
electric device 14. The telescopic controller 73 enters the pairing
signal transmission mode when the seatpost switch SW2 is pressed in
the control mode of the bicycle electric seatpost assembly SP. The
telescopic controller 173 enters the pairing signal transmission
mode when the suspension switch SW3 is pressed in the control mode
of the bicycle electric suspension FS. The first operating
controller 24B enters the pairing signal transmission mode when the
first function switch 24D is pressed in the control mode of the
first operating device 24. The second operating controller 26B
enters the pairing signal transmission mode when the second
function switch 26D is pressed in the control mode of the second
operating device 26. In the pairing mode and the paring signal
transmission mode, for example, the indicators 44, 80, 24E, and 26E
slowly blink.
The telescopic controller 73 periodically transmits pairing signals
PS21 including the first identification information ID21 of the
bicycle electric seatpost assembly SP in the pairing signal
transmission mode of the bicycle electric seatpost assembly SP. The
telescopic controller 173 periodically transmits pairing signals
PS22 including the second identification information ID22 of the
bicycle electric suspension FS in the pairing signal transmission
mode of the bicycle electric suspension FS. The first operating
controller 24B periodically transmits pairing signals PS11
including the identification information ID11 of the first
operating device 24 in the pairing signal transmission mode of the
first operating device 24. The second operating controller 26B
periodically transmits pairing signals PS12 including the
identification information ID12 of the second operating device 26
in the pairing signal transmission mode of the second operating
device 26.
The controller 34 wirelessly receives the pairing signals PS21,
PS22, PS11, and PS12 wirelessly transmitted from the telescopic
controller 73, the telescopic controller 173, the first operating
controller 24B, and the second operating controller 26B. The
controller 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. The controller 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 the first operating device 24,
and a value indicative of the left-hand side shifter such as the
second operating device 26. Thus, the controller 34 stores the
first identification information ID21, the second identification
information ID22, the identification information ID11, and the
identification information ID12 in the memory 34B. In the control
mode, the controller 34 recognizes a wireless signal transmitted
from a device paired with the controller 34 based on the first
identification information ID21, the second identification
information ID22, the identification information ID11, and the
identification information ID12 stored in the memory 34B. However,
the controller 34 does not respond to other wireless signals
transmitted from other devices. For example, the indicator 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, the first
operating device 24, and the second operating device 26. The
telescopic controller 73, the first operating controller 24B, and
the second operating controller 26B wirelessly receive the pairing
completion signal PCS and recognize that the pairing succeeded. For
example, the indicators 80, 180, 24E, and 26E quickly blinks after
reception of the pairing completion signal PCS.
The controller 34 returns to the control mode when a time T1 is
elapsed from sending of the pairing completion signal PCS. The
telescopic controller 73 returns to the control mode after the
specific time when the time T1 is elapsed after the telescopic
controller 73 wirelessly receives the pairing completion signal
PCS. The telescopic controller 173 returns to the control mode from
the paring signal transmission mode after the specific time when
the time T1 is elapsed after the telescopic controller 173
wirelessly receives the pairing completion signal PCS. The first
operating controller 24B returns to the control mode from the
paring signal transmission mode when the time T1 is elapsed after
the first operating controller 24B wirelessly receives the pairing
completion signal PCS. The second operating controller 26B returns
to the control mode from the paring signal transmission mode when
the time T1 is elapsed after the second operating controller 26B
wirelessly receives the pairing completion signal PCS. For example,
each of the indicators 44, 80, 180, 24E, and 26E turns off when the
mode is switched from the pairing mode and the paring signal
transmission mode to the control mode.
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, the controller 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 the telescopic
controllers 73 and 173.
In the control mode after the pairing, the controller 34 controls
the bicycle electric 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 bicycle electric device 14 in
the pairing mode. In such an embodiment, the telescopic controller
73 can be configured to wirelessly receive identification
information such as the identification information ID3 in the
pairing signal transmission mode. The telescopic controller 73 can
have a pairing mode which is different from the pairing signal
transmission mode and in which the telescopic controller 73
wirelessly receives identification information such as the
identification information ID3. Similarly, the telescopic
controller 173 can be configured to wirelessly receive
identification information such as the identification information
ID3 in the pairing signal transmission mode. The telescopic
controller 173 can have a pairing mode which is different from the
pairing signal transmission mode and in which the telescopic
controller 173 wirelessly receives identification information such
as the identification information ID3.
Second Embodiment
A bicycle wireless control system 212 in accordance with a second
embodiment will be described below referring to FIGS. 16 and 17.
The bicycle wireless control system 212 has the same structure
and/or configuration as those of the bicycle wireless control
system 12 except for the bicycle electric device 14 and the bicycle
electric 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 bicycle wireless control system 212
comprises a bicycle electric device 214, the at least one electric
telescopic apparatus 16, and a bicycle electric operating device
222. A controller 234 of the bicycle electric device 214 has
substantially the same configuration as that of the controller 34
of the bicycle electric device 14. For example, the controller 234
is configured to control the electric actuator 28 to upshift in
response to the first wireless signal WS11. The controller 234 is
configured to control the electric actuator 28 to downshift in
response to the second wireless signal WS12.
In this embodiment, as seen in FIG. 17, the bicycle electric device
214 and the at least one electric telescopic apparatus 16
synchronize in response to the operation signal WS1. The controller
234 is configured to wirelessly transmit the control signal CS to
the at least one electric telescopic apparatus 16 based on the
operation signal WS1 wirelessly transmitted from the bicycle
electric operating device 222. The first electrical switch 24A and
the second electrical 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 additional electrical switch 24G and the second
additional electrical switch 26G are omitted from the bicycle
electric operating device 222. Thus, the bicycle electric 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 the controller 234 to the second electric telescopic apparatus
FS based on the operation signal WS1. In this embodiment, the
controller 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. The controller 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. The controller 234 controls the
electric 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, the controller
234 controls the electric 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. The controller 234 controls the first electric
actuator 28 to upshift or downshift and controls the second
electric actuator 156 to keep the unlocked position of the
positioning structure 154 when the current gear stage changes
within a specific gear range (e.g., between the seventh and twelfth
gear stages). Thus, the controller 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. The controller 234 controls the
first electric actuator 28 to upshift or downshift and controls the
second electric actuator 156 to keep the lockout position of the
positioning structure 154 when the current gear stage changes
within a specific gear range (e.g., between the first and sixth
gear stages). Thus, the controller 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 first electric actuator 156 to
downshift in response to the second wireless signal WS12 and
controls the second electric actuator 156 to move the positioning
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.
The controller 234 controls the first electric actuator 156 to
upshift in response to the first wireless signal WS11 and controls
the second electric actuator 156 to move the positioning 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.
Third Embodiment
A bicycle wireless control system 312 in accordance with a third
embodiment will be described below referring to FIGS. 18 to 20. The
bicycle wireless control system 312 has the same structure and/or
configuration as those of the bicycle wireless control system 12
except that the electric rear derailleur RD is omitted from the
bicycle electric device 14. Thus, elements having substantially the
same function as those in the above embodiments 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 FIG. 18, the bicycle wireless control system 312
comprises a bicycle electric device 314, at least one electric
telescopic apparatus 316, and a bicycle electric operating device
322. In this embodiment, the bicycle electric device 314 includes
the bicycle electric seatpost assembly SP instead of the electric
rear derailleur RD. The at least one electric telescopic apparatus
316 includes the bicycle electric suspension FS. The bicycle
electric seatpost assembly SP has substantially the same
configuration as that of the bicycle electric device 14 (the
electric rear derailleur RD) of the first embodiment. The first
electrical switch 24A and the second electrical switch 246A are
omitted in the bicycle electric operating device 322.
As seen in FIG. 19, the electric actuator 56 of the bicycle
electric device 314 is configured to be operated in response to an
operation of the bicycle electric operating device 322. The
controller 73 has substantially the same configuration as that of
the controller 34 of the first embodiment. In this embodiment, the
controller 73 is configured to control the electric actuator 56 to
actuate the flow 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). The controller 73 is configured to
wirelessly transmit the control signal CS to the at least one
electric telescopic apparatus 316 based on the telescopic operation
signal WS2 wirelessly transmitted from the bicycle electric
operating device 322. The controller 73 is configured to wirelessly
transmit the control signal CS (e.g., the second control signal
CS2) to the at least one electric telescopic 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.
The controller 73 has a pairing mode in which the controller 73
receives the identification information ID22 of the at least one
electric telescopic apparatus 316. The switch SW2 is electrically
connected to the controller 73 to set the controller 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
electric telescopic apparatus 316 can include the bicycle electric
seatpost assembly SP instead of the bicycle electric suspension
FS.
Modifications
As seen in a bicycle wireless control system 412 illustrated in
FIG. 21, the bicycle electric suspension FS can be omitted from the
bicycle wireless control system 12 or 212 of the first or second
embodiment while the at least one electric telescopic apparatus 16
or 216 includes the bicycle electric seatpost assembly SP. In such
a modification of the bicycle wireless control system 12, for
example, the second additional electrical switch 26G can be omitted
from the bicycle electric operating device 22.
As seen in a bicycle wireless control system 512 illustrated in
FIG. 22, the bicycle electric seatpost assembly SP can be omitted
from the bicycle wireless control system 12 or 212 of the first or
second embodiment while the at least one electric telescopic
apparatus 16 or 216 includes the bicycle electric suspension FS. In
such a modification of the bicycle wireless control system 12, for
example, the first additional electrical switch 24G can be omitted
from the bicycle electric operating device 22.
As seen in a bicycle wireless control system 612 illustrated in
FIG. 23, an electric front derailleur FD can be added to the
bicycle wireless control system 12, 212, or 312 of the first,
second, or third embodiment instead of or in addition to the
bicycle electric suspension FS. In such a modification of the
bicycle wireless control system 12, for example, the bicycle
electric operating device 22, 222, or 322 can include an additional
electrical switch to operate the electric front derailleur FD. The
electric front derailleur FD includes a power supply 646 having
substantially the same structure as that of the power supply 46 of
the electric rear derailleur RD. The power supply 646 is configured
to supply electricity to a bicycle electric actuator 628 of the
electric component. In this modification, the electric component
includes the bicycle electric telescopic apparatuses SP and FS and
the bicycle electric transmissions RD and FD.

present application are merely identifiers, but do not have any
other meanings, for example, a particular order and the like.
Moreover, for example, the term "first element" itself does not
imply an existence of "second element," and the term "second
element" itself does not imply an existence of "first element."
The term "pair of," as used herein, can encompass the configuration
in which the pair of elements have different shapes or structures
from each other in addition to the configuration in which the pair
of elements have the same shapes or structures as each other.
The terms "a" (or "an"), "one or more" and "at least one" can be
used interchangeably herein.
Finally, terms of degree such as "substantially," "about" and
"approximately" as used herein mean a reasonable amount of
deviation of the modified term such that the end result is not
significantly changed. All of numerical values described in the
present application can be construed as including the terms such as
"substantially," "about" and "approximately."
Obviously, numerous modifications and variations of the present
invention are possible in light of the above teachings. It is
therefore to be understood that within the scope of the appended
claims, the invention may be practiced otherwise than as
specifically described herein.
