A bicycle shift operating device is basically provided with a base member, a shift unit, a first operating lever, a second operating lever, a first biasing element and a second biasing element. The first operating lever operates the shift unit by pivoting about a first pivot axis between a rest position and a shifting position. The second operating lever operates the shift unit by pivoting about a second pivot axis on the first operating lever between a rest position and a shifting position. The first biasing element biases the first operating lever towards the first rest position to keep the first operating member at the first rest position. The second biasing element biases the first operating lever towards its rest position in response to independent movement of the second operating lever from its rest position to its shifting position while the first operating lever remains at its rest position.
