At Wattbike, we understand the importance of accurate data. Without accurate data you cannot train precisely, enhance your performance or optimise your time when training.
The Wattbike is accurate to within 2% across the full range of Watts. This study has been independently verified by the South Australian Institute of Sport.
The Wattbike is designed to measure power output independent of the air brake, magnetic brake settings and environmental conditions. As with other ergometers it is not possible to have the same accuracy over the full range (for the Wattbike Pro the range is 0-3760Watts, for the Wattbike Trainer the range is 0-2000Watts). The mean accuracy of the Wattbike is typically within 2% (-0.42% +/- 1.21%) with retest variance typically better than 1% (0.42% +/- 0.46%) - South Australian Institute of Sport 31/03/2010.
|< 100 Watts||up to 6 % or 6 Watts|
|100 - 200 Watts||within 2%|
|200-500 Watts||within 1.5%|
|> 500 Watts||within 1 %|
|Over the full range||within 2 %|
To ensure complete confidence in the accuracy of data, each Wattbike is factory calibrated and will not need recalibration. Factory calibration delivers precise, accurate data which enables training optimisation.
