ABSTRACT:
A motorized bicycle front derailleur assembly is provided that includes a motor unit, a front derailleur and a motor linkage. The motor unit is configured to rotate an output shaft in first and second opposite rotational directions. The front derailleur includes a fixing body configured to be mounted to a bicycle frame, inner and outer links pivotally coupled to the fixing body at first and second pivot points, and a chain guide pivotally coupled to the inner and outer links to move between an inner shift position and an outer shift position. The first pivot point is located laterally closer to a center plane of the bicycle frame than the second pivot point. The motor linkage is operatively coupled to the output shaft of the motor unit and the inner link to move the chain guide between the inner and outer shift positions upon rotation of the output shaft.
