Abstract
An electric front derailleur is basically provided with a base, a chain guide, a linkage and an electric motor unit. The base is configured to be mounted to a bicycle. The chain guide is configured to guide a chain. The linkage movably couples the chain guide to the base in a forward-rearward direction to move the chain guide between a retracted position and an extended position in a mounted state where the base is mounted to the bicycle. The electric motor unit is supported on the base and operatively coupled to the linkage to move the chain guide between the retracted position and the extended position. The electric motor unit is arranged at least partly closer to the bicycle than the chain guide.
