The Wattbike Trainer has a resistance range of 0-2,000 Watts and you can recreate almost every Wattbike Pro resistance setting using a combination of the air and magnetic brakes. The essential difference is that the Wattbike Trainer provides a lighter range of resistance at the lower end which opens up Wattbike to everyone that the Wattbike Pro does not cater for. It’s also very useful for high cadence/low resistance exercise so will also suit high level track and endurance cyclists as well as children and general non-cyclists.
