Abstract:
An electric front derailleur includes a base member, a chain guide, a first link member, a second link member and an electric driving unit. The base member includes a mounting portion to be operatively mounted to a bicycle frame. The chain guide is movable with respect to the base member. The first link member movably connects the chain guide to the base member. The first link member is at least partially aligned with the chain guide in a lateral direction with the electric front derailleur in an installed position. The second link member movably connects the chain guide to the base member. The second link member is at least partially aligned with the chain guide in the lateral direction with the electric front derailleur in the installed position. The electric driving unit is operatively coupled to the chain guide to move the chain guide with respect to the base member.
