Whenever we get people on the Wattbike for the first time we're often asked, can I do a peak power test. The answer is of course yes but we always recommend a good warm-up. You then have a peak power figure to tell all of your mates about, but whether it be 750W or pushing the 2000W barrier the important figure is your power to weight ratio.
It's a simple calculation, power divided by weight, this gives a much more sensible comparison as heavier riders will often out-perform ligter riders when doing a peak power test on a static bike. Put them both out on the road, and especially when it goes uphill, and the lighter ride may well diappear into the distance.
Eddie, our sports scientists, has written a really useful piece on our Training Guide on the importance of Power-to-Weight ratio for cyclists, so take a look and don't forget to weigh yourself next time you are comparing peak power scores.
