The additional device408has substantially the same structure as the structure of the additional device8. The electrical control device411is electrically connected to the additional device408. The at least one electric component407includes additional devices9,409B, and409C. The additional devices409A and409B are electrically connected to the additional device9via an electric cable.

For example, the additional device9includes a rear derailleur. The additional device409A includes a front derailleur. The additional device409B includes a battery unit configured to supply electricity to the additional devices9and409A.

The electrical control device411is configured to wirelessly communicate with the electrical control device111. The wireless communication between the electrical control devices411and111is substantially the same as the wireless communication between the electrical control devices11and111. A wireless communicator unit of the electrical control device411is configured to wirelessly transmit a signal SG3. The wireless communicator unit118of the electrical control device111is configured to wirelessly transmit a signal SG4.

The additional device9is configured to execute upshifting or downshifting based on the signal SG1wirelessly transmitted from the electrical control device11to the electrical control device111. The additional device9is configured to control the additional device409A to execute upshifting or downshifting based on the signal SG3wirelessly transmitted from the electrical control device411to the electrical control device111.

As seen inFIG.30, the control system510includes the electrical control device11, the additional device8, the electrical control device111, the electrical control device411, an electrical control device511, the additional device408, and at least one electric component507. The electrical control device511has substantially the same structure as the structure of the electrical control device11. The at least one electric component507includes additional devices9and409B. The electrical control device511is electrically connected to the additional device409B. The additional device409B is omitted from the at least one electric component507.

The electrical control device511is configured to wirelessly communicate with the electrical control device111. The wireless communication between the electrical control devices111and511is substantially the same as the wireless communication between the electrical control devices11and111. The wireless communicator unit118of the electrical control device111is configured to wirelessly transmit a signal SG5. A wireless communicator unit of the electrical control device511is configured to wirelessly transmit a signal SG6.

The additional device9is configured to execute upshifting or downshifting based on the signal SG1wirelessly transmitted from the electrical control device11to the electrical control device111. The wireless communicator unit118of the electrical control device111is configured to wirelessly transmit the signal SG5in response to the signal SG3wirelessly transmitted from the electrical control device411to the electrical control device111. The additional device409B is configured to execute upshifting or downshifting based on the signal SG5wirelessly transmitted from the electrical control device111to the electrical control device511.

In the first and second embodiments and the modifications thereof, at least one of the circuit boards14and114can include a flexible printed circuit.

FIGS.5to19show examples of the predetermined condition used in the controller32of the electrical control device11. However, at least one of the examples shown in theFIGS.5and19can be omitted from the electrical control device11if needed and/or desired.

The terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein.

The phrase “at least one of” as used in this disclosure means “one or more” of a desired choice. For one example, the phrase “at least one of” as used in this disclosure means “only one single choice” or “both of two choices” if the number of its choices is two. For other example, the phrase “at least one of” as used in this disclosure means “only one single choice” or “any combination of equal to or more than two choices” if the number of its choices is equal to or more than three. For instance, the phrase “at least one of A and B” encompasses (1) A alone, (2), B alone, and (3) both A and B. The phrase “at least one of A, B, and C” encompasses (1) A alone, (2), B alone, (3) C alone, (4) both A and B, (5) both B and C, (6) both A and C, and (7) all A, B, and C. In other words, the phrase “at least one of A and B” does not mean “at least one of A and at least one of B” in this disclosure.

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.”
