[0065] For example, when the operation state of the electric suspension 50D is the locked state, the relative movement of the first suspension portion 50G and the second suspension portion 50H is restricted. For example, the locked state of the electric suspension 50D includes a state in which the first suspension portion 50G and the second suspension portion 50H slightly relatively move when the wheel 12 receives a strong force. For example, when the operation state of the electric suspension 50D is the locked release state, the relative movement of the first suspension portion 50G and the second suspension portion 50H is allowed. The operation state of the electric suspension 50D can include, instead of or in addition to the locked state and the locked release state, at least one of a plurality of operation states in which a damping force is different and a plurality of operation states in which a stroke amount is different.

[0137] For example, in a state where the communication unit 92 is attached to the housing 52, the cover member 82 is configured to cover the opening of the recess 80. For example, the communication unit 92 is disposed entirely in a space formed between the recess 80 and the cover member 82.
[0138] For example, the cover member 82 is formed of a resin material. For example, the cover member 82 is formed of a resin material having elasticity, and is attached to the housing 52 by being pressed into the recess 80. For example, the cover member 82 includes a thermosetting resin such as a polyester resin and an epoxy resin. For example, the cover member 82 can be configured of a material other than a resin material, as long as the material has a high transmittance of wireless signals. When an electric wave used in a wireless signal passes through a material having a high transmittance of wireless signals, the electric wave is less likely to be attenuated.
[0139] For example, the cover member 82 is configured to seal the space formed by the recess 80. For example, the cover member 82 is configured to inhibit water from intruding into the space formed by the recess 80. For example, the cover member 82 is configured to be attachable to the recess 80 in a state where the communication unit 92 is detached from the housing 52.
[0140] For example, the communication unit 92 includes a communication unit connector 92E. For example, the communication unit connector 92E has a columnar shape. The communication unit connector 92E is detachably attached to the electric connector 56A. The communication unit connector 92E is electrically connected to the electric connector 56A. The electric connection portion 56 is electrically connected to the control portion 54. For example, the electric connection portion 56 is electrically connected to the control portion 54 via the electric cable 56B.
[0141] For example, the electric connector 56A includes at least one first electric terminal, and the communication unit connector 92E includes at least one second electric terminal corresponding to the at least one first electric terminal. For example, the at least one second electric terminal is provided at an end portion of the communication unit connector 92E. The at least one first electric terminal is connected to the at least one second electric terminal, thereby electrically connecting the communication unit 92 to the control portion 54. For example, the assembly 50 is configured to supply power to the communication unit 92 in a state where the communication unit 92 is attached to the attachment portion 52M. For example, the assembly 50 is configured to be able to supply power to the communication unit 92 via the at least one first electric terminal and the at least one second electric terminal.
[0142] The control section 54 is configured to communicate with the communication unit 92 via the electrical connection section 56 in a state where the electrical connector 56A is connected to the communication unit 92. For example, the control section 54 is configured to communicate with the communication unit 92 via at least one first electrical terminal and at least one second electrical terminal. For example, the control section 54 is configured to communicate with the first control section 92B via the electrical connection section 56 and the communication unit connector 92E in a state where the electrical connector 56A is connected to the communication unit 92. For example, the control section 54 is configured to control the wireless communication section 92D. For example, the control section 54 is configured to transmit a communication signal that causes the first control section 92B to control the wireless communication section 92D to the first control section 92B.
[0143] For example, in a state where the electrical connector 56A is connected to the communication unit 92, when the second identification information does not correspond to the first identification information, the control section 54 is configured to control the electrical component 58. For example, when the second identification information does not correspond to the first identification information, the control section 54 is configured to limit the function of the electrical component 58.
[0144] The process in which the control section 54 controls the electrical component 58 when the second identification information does not correspond to the first identification information will be described with reference to the flowchart of FIG. 13. Figure 7 For example, if power is supplied to the control section 54, the control section 54 starts the process and proceeds to step S11 of the flowchart of FIG. 13. If the process of the flowchart of FIG. 13 ends, the control section 54 repeats the process starting from step S11 after a predetermined period, for example, until the supply of power is stopped. Figure 7 Figure 7 In step S11, the control section 54 determines whether the assembly 50 is connected with the communication unit 92. For example, when the assembly 50 is connected with the communication unit 92, the communication unit connector 92E is connected to the electrical connector 56A. When the assembly 50 is connected with the communication unit 92, the control section 54 proceeds to step S12. When the assembly 50 is not connected with the communication unit 92, the control section 54 ends the process.
[0145] In step S12, the control section 54 determines whether the first identification information corresponds to the second identification information. When the first identification information does not correspond to the second identification information, the control section 54 proceeds to step S13. When the first identification information corresponds to the second identification information, the control section 54 ends the process. In step S13, the control section 54 limits the function of the electrical component 58 and ends the process.
[0146]
[0147] For example, when the electric component 58 includes the electric motor 60, the function of the electric component 58 is limited, the control portion 54 controls the electric motor 60 to suppress the output of the electric motor 60. For example, when the electric component 58 includes the electric motor 60, the function of the electric component 58 is limited, the control portion 54 does not operate the electric motor 60.

[0149] The description related to the embodiments is an example of the manner in which the assembly for a human-powered vehicle and the external unit for a human-powered vehicle of the present application can be adopted, and is not intended to limit the manner. The assembly for a human-powered vehicle and the external unit for a human-powered vehicle of the present application can be adopted, for example, in the following alterations of the embodiments and in a combination of at least two alterations that are not contradictory to each other. In the following alterations, the same reference numerals are assigned to portions common to the embodiments, and the description thereof is omitted.
[0150] • As shown in FIG. 21, when the electric component 58 includes the second electric actuator 58C of the electric brake 50C, the control portion 54 can be configured to control the second electric actuator 58C such that the operating state of the electric brake 50C is maintained in the braking operating state in which the electric brake 50C operates, when the function of the electric component 58 is limited. Figure 8
[0151] Referring to FIG. 22, the processing by the control portion 54 when the electric component 58 includes the second electric actuator 58C of the electric brake 50C and the second identification information does not correspond to the first identification information will be described. For example, if power is supplied to the control portion 54, the control portion 54 starts the processing and proceeds to step S21 of the flowchart shown in FIG. 23. If the flowchart of FIG. 23 ends, the control portion 54 repeats the processing starting from step S21 after a predetermined period, for example, until the supply of power is stopped. Figure 9 Figure 9 Figure 9
[0152] In step S21, the control portion 54 determines whether the assembly 50 is connected with the communication unit 92. When the assembly 50 is connected with the communication unit 92, the control portion 54 proceeds to step S22. When the assembly 50 is not connected with the communication unit 92, the control portion 54 ends the processing.
[0153] In step S22, the control portion 54 controls the second electric actuator 58C such that the operating state of the electric brake 50C is maintained in the braking operating state in which the electric brake 50C operates, and then ends the processing.
[0154] • As shown in FIG. 21, when the electric component 58 includes the second electric actuator 58C of the electric brake 50C, the control portion 54 can be configured to control the second electric actuator 58C such that the operating state of the electric brake 50C is maintained in the braking operating state in which the electric brake 50C operates, when the function of the electric component 58 is limited. Figure 10 As shown, the external unit 90 can include an operation section 96 for operating the assembly 50. The operation section 96 is provided to the communication unit 92.

For example, the first control section 92B can be configured to control at least one of the position information detection section 92A, the wireless communication section 92D, and the display section 94, in accordance with an operation of the operation section 96.
[0155] • When the mounting section 52M is not mounted with the communication unit 92, the control section 54 can be configured to limit the function of the electric component 58. For example, a case where the mounting section 52M is not mounted with the communication unit 92 includes a case where the mounting section 52M is not mounted with the communication unit 92 via the electric connector 56A. For example, the control section 54 can be configured to, when the mounting section 52M is not mounted with the communication unit 92, limit the function of the electric component 58. Figure 7 In step S11 of the flowchart, when the communication unit 92 is not connected, the process proceeds to step S13.
[0156] • The cover member 82 can not contain a material having a high transmittance of a wireless signal, as long as the transmittance of the wireless signal is high. For example, the cover member 82 can be formed thinner than the housing 52.
[0157] • The assembly 50 includes the housing 52 having the mounting section 52M detachably mounting the communication unit 92 including the position information detection section 92A, the control section 54 provided to the housing 52, the electric connection section 56 having the electric connector 56A detachable with respect to the communication unit 92 and electrically connected with the control section 54, and the electric component 58 controlled by the control section 54. The position information detection section 92A can acquire information related to a position by receiving an electric wave from the outside, and the control section 54 can omit other structures as long as it is configured to communicate with the communication unit 92 via the electric connection section 56 in a state where the electric connector 56A is connected to the communication unit 92.
