The invention provides a transmission of a bicycle. The transmission of the bicycle comprises a bicycle frame fixing base, a drive source, a linkage assembly and a guide chain frame, wherein the drive source is provided with a drive arm; the linkage assembly is provided with a first linkage base and a second linkage base, the top end of the first linkage base is in pivot connection with the bicycle frame fixing base through a first shaft part and extends outwards to form a first branch arm, the tail end of the branch arm is in pivot connection with the drive arm through a second shaft part, and the top end of the second linkage base is in pivot connection with the bicycle frame fixing base through a third shaft part; the guide chain frame is in pivot connection with the bottom end of the first linkage base through a fourth shaft part and in pivot connection with the bottom end of the second linkage base through a fifth shaft part, so that the guide chain frame can be driven by the first and second linkage bases to change positions. Accordingly, the transmission of the bicycle can reduce loads of the drive source, and the service life is prolonged.
