A bicycle shift operating device (110a) comprises a mounting part (30), a first operating member (32) movable relative to the mounting part (30) from a first operation start position (HP1) such that the first operating member (32) returns to the first operation start position (HP1) upon completion of a shifting operation; and a first signal generator (36) having a first movable contact (80) operatively connected to the first operating member (32) to move in accordance with movement of the first operating member (32) and a first stationary contact (82) non-rotatably mounted relative to the mounting part (30) to selectively contact and separate from the first movable contact (80). The first signal generator (36) is configured to turn on a signal for changing the shift position of the bicycle shift operating device (110a) by one position in a first direction from the current shift position in response to the first operating member (32) being moved from the first operation start position (HP1) to a first position (P1). The first signal generator (36) is configured to turn off the signal in response to the first operating member (32 reaching a position different from the position where the signal was turned on while in the process of returning from the first position (P1) to the first operation start position (HP1). A second operating member (34) is pivotally connected to the first operating member (32) to pivot independently of the first operating member (32) when the second operating member (34) pivots from the second operation start position (HP2) and to pivot integrally with the first operating member (32) when the first operating member (32) pivots from the first operation start position (HP1).
