The best power meters are recording devices that provide numerical data of a rider's output during a given effort, which is most commonly read in watts. They are typically incorporated into pedals, crank arms, or chainsets and use Bluetooth for real-time or post-ride analysis. While tracking your power output is certainly the main reason for owning one of the best power meters, they can also measure the balance of power between legs and pedalling smoothness, both of which are considered key metrics in improving performance. This is why power meters have become indispensable tools for professionals, trainers, and racers looking to find gains.

Today, power meters are becoming increasingly popular among casual cyclists, too, looking to gain deeper insights into their riding. Technological advances have made them more compatible with cycling computers, apps, smartwatches, and phones, and a decrease in cost has made them far more approachable for non-professionals.

I’ve been hooked on bikes ever since the age of 12 and my first lap of the Hillingdon Cycle Circuit in the bright yellow kit of the Hillingdon Slipstreamers. For a time, my cycling life centred around racing road and track. 

But that’s since broadened to include multiday two-wheeled, one-sleeping-bag adventures over whatever terrain I happen to meet - with a two-week bikepacking trip from Budapest into the mountains of Slovakia being just the latest.

I still enjoy lining up on a start line, though, racing the British Gravel Championships and finding myself on the podium at the enduro-style gravel event, Gritfest in 2022.
