The invention belongs to the technical field of gearboxes, and provides a novel bicycle transmission which specifically comprises a shell, an input part, a speed changing part and an output part, theinput part is installed in the shell, the speed changing part is installed in the shell, the speed changing part is in meshing transmission with the input part, the output part is installed on the shell, and the output part is in transmission connection with the speed changing part. The input part comprises an input shaft and driving teeth, and the driving teeth are mounted on the input shaft; thespeed changing part comprises driven teeth, a speed changing separation sleeve, a cam shaft and a clutch roller, the driven teeth are installed on the surface of the speed changing separation sleeve,the cam shaft is installed in the speed changing separation sleeve, the cam shaft is provided with a cam, and the clutch roller abuts against the cam shaft and abuts against the speed changing separation sleeve; the output part comprises output teeth and an output shaft sleeve, the output shaft sleeve is installed on the input shaft, and the output teeth are installed in the output shaft sleeve and are in meshing transmission connection with the driven teeth. In conclusion, a shaft sleeve combined gear shifting mode is adopted, the performance of the transmission is improved, six-gear speed changing can be achieved, and the transmission is suitable for use and popularization.
