A drivetrain of an electric bike is provided. The drivetrain includes an outer rotor type motor, a shaft gear, a crankshaft and a single-stage velocity-reduction driving assembly. The outer rotor type motor includes a stator assembly, a rotor assembly and a housing. The rotor assembly is disposed to the housing. The shaft gear includes a joint portion and a gear portion. The joint portion is disposed to the housing. The single-stage velocity-reduction driving assembly is configured around the crankshaft and includes a driving gear. A central axis of the shaft gear and a central axis of the crankshaft are substantially parallel to each other and non-coaxial, and the driving gear directly meshes with the gear portion. Accordingly, the drivetrain of the electric bike of the present invention has the advantages of easier assembly and having lower cost.
