     As seen in  FIG. 4 , the second wire attachment part  30  is farther from the operating member  14  than at least one of the hydraulic cylinder  32  and the piston  34 . In this embodiment, the second wire attachment part  30  is farther from the operating member  14  than the hydraulic cylinder  32  and the piston  34 . However, the second wire attachment part  30  can be closer from the operating member  14  than at least one of the hydraulic cylinder  32  and the piston  34 . 
     The control wire  28  is pulled via the first wire attachment part  26  when the operating member  14  is pivoted relative to the base member  12  from the first rest position P 11  toward the first operated position P 12 . Thus, the second wire attachment part  30  is pivoted relative to the hydraulic cylinder  32  about the cable pivot axis A 3 , moving the piston  34  relative to the hydraulic cylinder  32  from the initial position P 31  toward the actuated position P 32 .

     As seen in  FIG. 9 , the hydraulic unit  22  can be omitted from the bicycle operating device  10 . In a case where the hydraulic unit  22  is omitted from the bicycle operating device  10 , the control wire  28  extends through the first wire passageway  12 G without through the second wire passageway  12 H. The bicycle operating device  10  is operatively coupled to a wire-actuated bicycle component BC 3  via a control wire C 31  of a control cable C 3 . An end C 31 A of the control wire C 31  is attached to the first wire attachment part  26 . The control cable C 3  includes an outer casing C 32 . The control wire C 31  is movably provided in the outer casing C 32 . Examples of the control cable C 3  include a Bowden cable.

While the second direction D 2  is different from the first direction D 1  in this embodiment, the second direction D 2  can be equal to the first direction D 1 . The additional operating member  46  is pivotally coupled to the base member  12  via the operating member  14 . Thus, the additional operating member  46  is pivotable relative to the base member  12  about the operating pivot axis A 1  together with the operating member  14 . 
     As seen in  FIGS. 10 and 11 , the additional operating member  46  is pivotable relative to the operating member  14  about the additional operating pivot axis A 2  between a second rest position P 21  and a second operated position P 22 . In this embodiment, the second direction D 2  is a circumferential direction defined about the additional operating pivot axis A 2 . The additional operating member  46  is biased by a second biasing member  47  toward the second rest position P 21  relative to the base member  12 . The additional operating member  46  is at the second rest position P 21  in a state where the additional operating member  46  is in contact with the operating member  14 . Thus, the additional operating member  46  is at the second rest position P 21  in a state where the additional operating member  46  is not operated by the user. 
     As seen in  FIG. 3 , the additional operating member  46  is at least partially closer to the first end portion  12 A than the operating member  14  in a rest state where the operating member  14  is at the first rest position P 11 . However, the additional operating member  46  can be farther from the first end portion  12 A than the operating member  14  in the rest state where the operating member  14  is at the first rest position P 11 . 
     The additional operating pivot axis A 2  is disposed above the operating pivot axis A 1  in the mounting state where the bicycle operating device  10  is mounted to the handlebar H.

The electrical switch  50  is disposed at the additional operating member  46  to provide an electric signal in response to a movement of the additional operating member  46 . In this embodiment, the electrical switch  50  is attached to the additional operating member  46  to move together with the additional operating member  46  in the second direction D 2 . The electrical switch  50  provides the electric signal in response to the movement of the additional operating member  46  in the second direction D 2 . While the electrical switch  50  is a normally open switch in this embodiment, other type of switches can be applied to the bicycle operating device  10 . 
     While the electrical switch  50  is used as a shift control switch in this embodiment, the electrical switch  50  can be used as a switch other than the shift control switch. For example, the additional operating member  46  can be used as a suspension control switch in a case where the electrical bicycle component BC 2  includes the electric suspension. The additional operating member  46  can be used as a seatpost control member in a case where the electrical bicycle component BC 2  includes the electric seatpost. 
     As seen in  FIGS. 11 and 12 , the additional operating member  46  includes a lever  52 . The lever  52  includes a first lever end  52 A and a second lever end  52 B.

     The second biasing member  47  is disposed between the electrical switch  50  and the actuation part  56  to bias the additional operating member  46  toward the second rest position P 21 . Thus, the additional operating member  46  is positioned at the second rest position P 21  by the receiving part  58  in a state where the additional operating member  46  is not operated by the user. 
     The bicycle operating device  10  comprise a button element  60  to transmit, to the electrical switch  50 , the movement of the additional operating member  46  in the second direction D 2 .

The second biasing member  47  is held by the projection  56 A and the button element  60 . 
     The button element  60  is in contact with the projection  56 A in a state where the additional operating member  46  is at the second operated position P 22 . This contact closes the electrical switch  50  to provide the electric signal. The electrical switch  50  is open not to provide the electric signal when the additional operating member  46  is returned to the second rest position P 21 . 
     As seen in  FIGS. 12 and 13 , the bicycle operating device  10  further comprises a wireless communication unit  62  connected to the electrical switch  50  to transmit a wireless signal based on an input from the electrical switch  50 .

The electronic substrate  63  is secured to the additional operating member  46  (e.g., the attachment part  54 ). The bicycle operating device  10  comprises an antenna  64  connected to the wireless communication unit  62 . The antenna  64  is mounted on the electronic substrate  63 . The wireless communication unit  62 , the electronic substrate  63 , and the antenna  64  are disposed in the accommodation space  54 C of the attachment part  54 . The wireless communication unit  62  wirelessly transmits the wireless signal based on the electric signal via the antenna  64 . The antenna  64  can be included in the wireless communication unit  62  or can be integrally provided with the wireless communication unit  62  as a single module or unit.

Thus, the wireless communication unit  62  can also be referred to as a wireless communication circuit  62  in the present application. The processor  62 A includes a central processing unit (CPU) and a memory controller. The memory  62 B is connected to the processor  62 A. The memory  62 B includes a read only memory (ROM) and a random access memory (RAM). The ROM includes a non-transitory computer-readable storage medium.

The memory  62 B (e.g., the ROM) stores a program. The program is read into the processor  62 A, and thereby functions of the wireless communication unit  62  (e.g., at least part of functions of the signal generating circuit  62 C and the signal transmitting circuit  62 D). 
     The signal generating circuit  62 C generates wireless signals based on the electric signal input from the electrical switch  50 . The signal generating circuit  62 C superimposes digital signals on carrier wave using a predetermined wireless communication protocol to generate the wireless signals. The signal transmitting circuit  62 D transmits the wireless signal via the antenna  64  in response to the electric signal input from the electrical switch  50 . In this embodiment, the signal generating circuit  62 C can encrypt control information (e.g., shift information) to generate encrypted wireless signals. The signal generating circuit  62 C encrypts digital signals stored in the memory  62 B using a cryptographic key. The signal transmitting circuit  62 D transmits the encrypted wireless signals. Thus, the wireless communication unit  62  wirelessly transmits the wireless signal to upshift or downshift the electric shifting device BC 2  when the electrical switch  50  is closed to provide the electric signal. 
     Further, the signal receiving circuit  62 E receives a wireless signal from the electric shifting device BC 2  via the antenna  64 .

     Second Embodiment 
     A bicycle operating device  210  in accordance with a second embodiment will be described below referring to  FIGS. 14 and 15 . The bicycle operating device  210  has the same structure and/or configuration as those of the bicycle operating device  10  except for the wireless communication unit  62 . 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  FIG. 14 , the bicycle operating device  210  comprises the base member  12  and the operating member  14 . Unlike the bicycle operating device  10  of the first embodiment, the wireless communication unit  62  and the antenna  64  are omitted from the bicycle operating device  210 . Instead, as seen in  FIG. 15 , the bicycle operating device  210  further comprises a signal controller  262  connected to the electrical switch  50  to transmit a control signal via an electrical control cable C 4  based on an input from the electrical switch  50 . The bicycle operating device  210  is operatively connected to an electrical bicycle component BC 4  via the electrical control cable C 4 . 
     In this embodiment, the signal controller  262  transmit the control signal by using power line communication (PLC) technology. The power line communication technology is used for communicating between electrical components. Power line communication (PLC) carries data on a conductor that is also used simultaneously for electric power transmission or electric power distribution to the electrical component. Since the PLC has been known in the bicycle field, it will not be described in detail here for the sake of brevity. 
     As seen in  FIG. 15 , the signal controller  262  includes the processor  62 A, the memory  62 B, a signal generating circuit  262 C, a PLC controller  262 D, and the voltage regulator  62 F. The signal generating circuit  262 C generates the control signal based on the electric signal from the electrical switch  50 . The PLC controller  262 D superimposes the control signal on the power source voltage applied to the electrical control cable C 4 . 
     With the bicycle operating device  210 , it is possible to obtain substantially the same effects as those of the bicycle operating device  10  of the first embodiment. 
     Furthermore, the bicycle operating device  210  further comprises the signal controller  262  connected to the electrical switch  50  to transmit the control signal via the electrical control cable C 4  based on the input from the electrical switch  50 .

     It will be apparent to those skilled in the bicycle field from the present disclosure that the above embodiments can be at least partly combined with each other. 
     The term “comprising” and its derivatives, as used herein, are intended to be open ended terms that specify the presence of the stated features, elements, components, groups, integers, and/or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers and/or steps. This concept also applies to words of similar meaning, for example, the terms “have”, “include” and their derivatives. 
     The terms “member”, “section”, “portion”, “part”, “element”, “body” and “structure” when used in the singular can have the dual meaning of a single part or a plurality of parts. 
     The ordinal numbers such as “first” and “second” recited in the 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. 
     Finally, terms of degree such as “substantially”, “about” and “approximately” as used herein mean a reasonable amount of deviation of the modified tem′ such that the end result is not significantly changed. 
     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.
