A bicycle freewheel selection mechanism, enables the bicycle pedals to remain static during gear changes. The bicycle freewheel selection mechanism comprises a rear wheel hub 110 having an internal clutch 150 capable of selectively engaging a rear freewheel when activated; and an activation means for remote location on a bicycle frame arranged so as to permit a user to selectively engage the rear freewheel. The activation may occur by means of a cable, a signaling system or via a conduit, such as hydraulically. In use, the freewheel may be locked when a gear change is made, thereby causing the chain to rotate causing a freewheel device on the cranks to overrun and the gear change to occur.
