A bicycle with a novel gearbox transmission bicycle transmission comprises a frame, the frame is of an L-shaped structure, a long arm part of the L-shaped structure forms a cross beam, a short arm part of the L-shaped structure forms a longitudinal beam, a handlebar and a bicycle head are rotatably arranged at the front end of the cross beam, the bicycle head is connected with a front wheel through a roller set, and the front wheel is connected with a rear wheel through a roller set. A saddle is arranged at the joint of the cross beam and the longitudinal beam, the tail end of the longitudinal beam is integrally connected with a fixing ring, a pedal ring with pedals is arranged in the fixing ring, the rear side of the fixing ring is connected with a gearbox body internally provided with a speed change mechanism, and the speed change mechanism is in driving connection with the pedal ring. And a rear wheel which is connected with the speed change mechanism and is driven by the speed change mechanism to rotate is arranged in the speed change box body in a penetrating manner. Interference from the external environment is small, a transmission structure of a product is concentrated in the gearbox, maintenance is convenient, and the embarrassing situation that a whole vehicle is disassembled at a damaged position is avoided. Gear transmission is adopted, and the transmission efficiency is greatly improved.
