The invention belongs to the technical field of electric bicycles, and particularly relates to a centered-motor mounting mechanism of an electric bicycle. The centered-motor mounting mechanism comprises a lifting frame (2) and a driving machine (4), wherein the rear end of the lifting frame (2) is fixedly connected to the end part of a bottom fork (1) of the electric bicycle, and a notch for being fixedly connected with a shaft sleeve (3) of a center shaft is formed in the front end of the lifting frame (2); the driving machine (4) comprises a centered motor (4-1), and a tension frame (4-3) with a tension wheel (4-2), wherein the centered motor (4-1) is mounted on the lifting frame (2), and the tension frame (4-3) is fixedly connected to the edge of the centered motor (4-1); the center shaft with a wheel disc (7) is mounted on the shaft sleeve (3) of the center shaft. The centered-motor mounting mechanism disclosed by the invention has the advantages that the structure of the transmission system is compact, and the driving performance is excellent; through the adoption of the lifting frame, the connecting strength between the bicycle frame and the motor is improved, and besides, the convenience of mounting and demounting is improved.
