A bicycle front derailleur is basically provided with a base member, a movable member, an electric driving unit and a biasing member. The base member includes a bicycle mounting portion. The movable member is movably supported with respect to the base member between a first position and a second position that is farther than the first position from the base member. The electric driving unit is operatively coupled to the movable member to move the movable member between the first position and the second position. The biasing member is operatively disposed between the base member and the movable member to bias the movable member towards the second position.
