The invention discloses a transmission connector of an electric bicycle. The transmission connector comprises a connecting body. Stepped through holes are formed inside the connecting body. The large-aperture section of the connecting body is provided with an inner thread for connecting. A first bearing is disposed in the second stepped through hole of the connecting body. A plurality of steps are disposed outside the connecting body. A plurality of pawl grooves are peripherally distributed in the middle of the outer side of the connecting body. A pawl is disposed in each pawl groove, and a pawl spring is disposed on the pawl. A ratchet is mounted on the outer lateral wall of the connecting body through a second bearing. The pawl springs, the pawls and the ratchet are matched to form a ratchet mechanism. A rear driven gear fixedly sleeves the ratchet. A fixing cover is disposed on the second bearing. The fixing cover is matched with the ratchet in a threaded manner. The transmission connector is simple in structure, high in transmission efficiency, good in stability, free of ratchet structure failure, capable of facilitating mounting connection between a drive motor and a transmission assembly, and low in cost.
