The invention discloses a bicycle brake crank which comprises a base frame and a handle. The handle comprises a handle body. One side of the upper end of the handle body extends to form an arc-shaped handheld portion. A brake cable installation groove is formed in the upper end of the handle body. A through hole is formed in the lower end of the handle body. A handle installation groove is formed in one side of the upper end of the base frame. The handle is riveted into the handle installation groove through a rivet penetrating through the through hole. The other end of the upper end of the base frame is connected with a fine adjusting nut. A pipe hole is formed in the lower end of the base frame. An annular groove coaxial with the pipe hole is formed in the side face of the lower end of the base frame. A locking circular ring is arranged in the annular groove. The upper end of the locking circular ring is provided with an opening and extends upwards to form an extension base. The extension base is located in the base frame and fixed into the base frame through a fixing screw. The bicycle brake crank has the technical advantages that the base frame and a handlebar are locked through the locking circular ring, the locking method is simple, and the locking effect is good; the locking circular ring and the base frame can be separately colored, the visual impression of the bicycle brake crank is improved, and the ornamental value is achieved.
