A bicycle transmission is basically provided with an input gear a plurality of second rotating bodies, a second shaft and a clutch mechanism. The input gear receives a drive force. The rotation of the input gear is transmitted the second rotating bodies. The second shaft is coaxially provided with a plurality of second rotating bodies and rotatably supports the second rotating bodies. The clutch mechanism is provided with a control shaft disposed inside the second shaft and which is rotatable relative to the second shaft. The clutch mechanism switches the coupling state between the second rotating bodies and the second shaft by rotating the control shaft relative to the second shaft. The clutch mechanism rotates the control shaft by transmitting the drive force that is applied to the input gear to the control shaft.
