The invention provides a power-driven pulley assembly. The power-driven pulley assembly comprises an electric wheel, a wheel fixing block and a fixing piece; a hub motor is arranged in the electric wheel, and a centre shaft rod is fixed to the center of a circle of one lateral face of the electric wheel; the wheel fixing block is in a strip shape, the length of the wheel fixing block is larger than the radius of the electric wheel, and a plurality of middle holes are formed in at least two faces of the wheel fixing block; and the fixing piece is in a plate shape and is fixed to the middle holes through screws, at least two sets of component holes and at least two sets of fixing holes are formed in the fixing piece, each set of component holes comprises one to three component holes, and each set of fixing holes comprises one to three fixing holes. By means of the power-driven pulley assembly, electric power can be better provided, the operative difficulty is reduced, the physical output is reduced, and the kinetic energy conversion using rate is improved; the power-driven pulley assembly is high in universality and simple in operation, a user can easily complete refitting by himself, resources are greatly saved, and meanwhile the good doing experience can be brought to the user; and the structure is simple, refitting and maintaining are easy, technical popularization is easy, and a market prospect is excellent.
