the first end portion includes a mounting surface having a curved shape corresponding to a drop-down handlebar.

11. The bicycle operating device according to claim 9 , wherein

the base member includes a grip portion arranged between the first end portion and the second end portion.

12. The bicycle operating device according to claim 9 , wherein

the second end portion includes a pommel portion.

13. The bicycle operating device according to claim 9 , wherein

the first end portion is configured to be coupled to a bar end of the handlebar in the mounting state.

14. The bicycle operating device according to claim 9 , wherein

the brake operating member is pivotable relative to the base member between a first rest position and a first operated position, and

the additional operating member is at least partially closer to the first end portion than the brake operating member in a rest state where the brake operating member is at the first rest position.

15. The bicycle operating device according to claim 2 , wherein

the brake operating member is pivotally coupled to the base member in a first direction,

the additional operating member is pivotally coupled to the brake operating member in a second direction,

the second direction is different from the first direction, and

the electrical switch is configured to provide an electric signal in response to a movement of the additional operating member in the second direction.

16. The bicycle operating device according to claim 15 , wherein

the brake operating member is pivotable relative to the base member about the first pivot axis in the first direction,

the additional operating member is pivotable relative to the brake operating member about the second pivot axis in the second direction, and

the second pivot axis is non-parallel to the first pivot axis.

17. The bicycle operating device according to claim 15 , wherein

the brake operating member is pivotable relative to the base member about the first pivot axis in the first direction, and

the additional operating member is pivotable relative to the brake operating member about the second pivot axis in the second direction.

18. The bicycle operating device according to claim 2 , further comprising:

a power supply connected to at least one of the electrical switch and the wireless communication unit.
