The invention discloses a bottom fork and motor connection structure of an electric bicycle. The bottom fork and motor connection structure comprises a bottom fork and a motor. The bottom fork is shaped like a Chinese character 'kai' structurally, and comprises a first branch arm and a second branch arm. The tail end of the first branch arm is fixed in a groove, formed by a motor shell, in one side of the motor through an anti-pulling piece and a compression screw. A motor wire outlet lug adhered to the first branch arm is processed on the left side of the first branch arm of the bottom fork and positioned on the outer side of the motor. The second branch arm is connected to a bottom fork bearing block through a bottom fork connection screw. The bottom fork bearing block sleeves one end of an output shaft of the motor through a bearing and is in rotatable connection with the output shaft. An inner ring of the bearing is fastened by a shaft-end nut. The bottom fork and motor connection structure of the electric bicycle has the advantages of high connection strength and assembly flexibility, low production cost, convenience in mounting and the like.
