A bicycle transmission includes a hub 10 that is switchable between a free wheel state and a fixed wheel state during use. The hub 10 comprises: a hub body 20; a sprocket carrier connected to the hub via a freewheel mechanism; a clutch mechanism comprising at least one fixed clutch plate 61 that is rotationally fixed with the hub body and at least one rotatable clutch plate 62 that is rotationally fixed with the sprocket carrier. When engaged the clutch locks the sprocket carrier with respect to the hub. Also disclosed is a tensioner (101 figure 9) separate from a rear gear shifting mechanism (8, figure 9) the tensioner being fixable in position when the hub is in a fixed-wheel state. A controller (135, figure 8) is described which synchronises operation of the hub 10 and the tensioner 101.
