A rear derailleur of a bicycle includes a fixing portion having a first pivot portion and a second pivot portion, a linkage assembly including a first connecting shaft and a second connecting shaft, a moving portion, a chain guide assembly connected to the moving portion, and a driving assembly. An end of the first connecting shaft is pivotally connected to the first pivot portion via a first pivot. An end of the second connecting shaft is pivotally connected to the second pivot portion via a second pivot. The moving portion has a third pivot portion pivotally connected to the first connecting shaft via a third pivot and a fourth pivot portion pivotally connected to the second connecting shaft via a fourth pivot. The driving assembly is disposed on either the first connecting shaft or the second connecting shaft and drives one of the first to fourth pivots to drive the linkage assembly to pivot.
