A drive assembly of an electric bicycle is disclosed. A shell tube of an electric bicycle is transfixed with a crank shaft sheathed with an outer shaft set. The outer shaft set links to a tubular motor set. A first side of the crank shaft is provided with a left positioning set sheathed and limited in a left hole of the shell tube. A second side of the crank shaft is provided with a right positioning set sheathed and limited in a right hole of the shell tube. The right positioning set is fixed with a chain wheel set. A displacement of the crank shaft pulled by a bicycle chain is detected by a torque detection unit, and a torque is accessed by a control unit based upon the displacement to control the output power of the tubular motor set, thereby assisting pedaling the bicycle with feet.
