The invention discloses a mid-mounted motor of an electric bicycle. The mid-mounted motor comprises a connecting sleeve, a machine casing, a middle shaft, a sprocket wheel, and an elastic deformation sleeving pipe, wherein the machine casing and the connecting sleeve are connected integrally; the middle shaft is rotationally assembled in the connecting sleeve through a first supporting bearing and a second supporting bearing; the sprocket wheel sleeves the middle shaft; the elastic deformation sleeving pipe sleeves the middle shaft and can generate circumferential direction deformation when being subject to circumferential direction torsional force; external threads are formed in one end of the connecting sleeve, and spacing steps are molded at the other end of the connecting sleeve; one end of the elastic deformation sleeving pipe is fixed to the middle shaft, and the other end of the elastic deformation sleeving pipe is connected with the sprocket wheel; two sets of magnetic loops which are distributed at intervals are arranged on the elastic deformation sleeving pipe; a signal processing circuit board is fixedly arranged on the inner wall of the connecting sleeve; hall elements corresponding to the two sets of the magnetic loops are integrated on the signal processing circuit board; the signal processing circuit board is connected with a motor controller through a signal outgoing line. The mid-mounted motor of the electric bicycle, disclosed by the invention, is simple and compact in structure, and easy to mount.
