A bicycle hydraulic operation device comprises a bracket, a hydraulic cylinder, a piston a lever, and a first biasing member. The bracket includes a gripping portion configured to be gripped by a rider. The piston is disposed within the hydraulic cylinder and movable between an initial position and an actuated position. The lever is pivotally mounted to the bracket around a first axis and operatively coupled to the piston to move the piston in response to pivotal movement of the lever from a rest position to an operated position. The first biasing member is operatively coupled to the piston and the lever outside the hydraulic cylinder such that the first biasing member biases the piston toward the initial position and biases the lever toward the rest position.
