There is also a small amount of friction to overcome, both in the bike and between the bike and the road (hence the use of smoother, thinner tyres).Īs a guide, below are some approximate cycling power figures for various speeds of cycling: Speed - kmh (mph)įigures assume a flat road on a windless day. ![]() The basic idea is that we need power to overcome air resistance (more important on flat / downhill sections) and gravity (important when going up hills!). ![]() Most of us don't want to spend large amounts of money on a Cycling Power Meter for our bikes, and unless we are training very hard and with particular goals it is more of a luxury than a necessity.īut it is still useful and interesting to know how much power we can generate when we cycle and an understanding of cycling power also makes it clear why we can all increase our speed quite quickly when we start, but it becomes progressively harder to make small improvements as we get faster!
