Most exercise bikes fail completely to replicate the sensation of cycling. Several modern models do a better job, but the shiny new Wattbike is arguably the king of the gym. The only trainer sanctioned by British Cycling, it uses an air flywheel and a magnetic resistiance brake to simulate hills or flats, while a computer monitors every conceivable paramater to give a breakdown of your cycling that can be as detailed as you like.
