The disclosure provides a bicycle front derailleur configured to be mounted on a bicycle frame. The bicycle front derailleur includes a fixed component, a chain guide, a linkage assembly, and an adjustment component. The fixed component is configured to be mounted on the bicycle frame. Two opposite ends of the linkage assembly are respectively and pivotably disposed on the fixed component and the chain guide. The adjustment component is pivotably disposed on the fixed component. The adjustment component is configured to press against the bicycle frame so as to adjust a position of the bicycle front derailleur with respect to the bicycle frame.

A bicycle derailleur comprises a base member, a linkage structure, and a motor unit. The linkage structure includes a first link pin rotatably mounted to the base member about a first pivot axis. The motor unit is configured to apply rotational force to the first link pin to rotate the first link pin relative to the base member about the first pivot axis.

A front sprocket assembly comprises a first sprocket and a second sprocket. The second sprocket includes a second sprocket body and a plurality of second sprocket teeth. At least one tooth of the plurality of second sprocket teeth includes a less chain-interference recess provided to the second axially inwardly facing surface. The less chain-interference recess is configured to reduce interference between the at least one tooth of the plurality of second sprocket teeth and a chain in an upshifting operation in which the chain is shifted from the first sprocket toward the second sprocket. The less chain-interference recess has a radially innermost end positioned radially inwardly from a tooth bottom circle of the plurality of second sprocket teeth. A radial distance radially defined from the tooth bottom circle to the radially innermost end with respect to a rotational center axis is equal to or larger than 1.0 mm.
