7 Best Power Meters UK 2024 | 4iiii, Avio and More

Our choice for the no. 1 spot, is this this power meter from Powertap. The G3 Hub offers highly accurate readings over long periods of time, is relatively easy to set up both in terms of installation and calibration, and is very durable.

It also offers excellent value for money when compared to some of the more expensive options available. But most importantly, Powertap hubs have been a trusted brand for almost 15 years, and each generation improves on the last. Many cyclists swear by the G3, and it is widely considered to be the most accurate power meter on the market.

If you've been looking through this article and like the idea of  a power meter, but not the prices, it may be worth considering this budget option from 4iiii. If you're looking for a more affordable power meter, without too many sacrifices, this is the one for you.

At only 9 g, it barely adds any weight to your bike and only takes around five minutes to fit. It is a left sided-only power meter, but you're able to calibrate it for any imbalance between legs in order to get more accurate readings. 

You may notice some similarities between the second and third entries on our list as they're essentially premium and budget versions of the same product line which offers some of the best lightweight and most accurate power meters on the market. This is the premium version, but that doesn't you won't get value for money.

Measuring both legs independently may offer a much higher level of accuracy than a single side, but requires double the materials to produce, resulting in a higher price. If you're looking for individual leg accuracy, this is one of the best you can get, if not, take a look below.

This offering from Magene gives you a lot for your money when compared to some other power meters on the market today. As well as the accessory bag and choice of three different colour shells, this power meter does some neat things under the hood.

Like other dual sided options, this measures each leg separately, so you can see any imbalances in your training. It also monitors the smoothness of your peddling and torque effectiveness in order to maximise your cycling efficiency.

Spider-crank power meters offer a balanced way to measure your output at a relatively low fee, and could be a good option to consider depending on the type of bike you own. The X-Power S is a very reliable choice for the money, provided you're able to fit it to your bike.

Unlike other power meters, which should fit a variety of bikes provided you're able to get the right size, spider-crank power meters replace the original spider-crank, which is sometimes part of the chainring. This means that brands like Shimano are unsuitable for this type of meter.

Quarq are a brand leader when it comes to power meters, offering some of the best and highest quality items on the market. This is the choice for the extreme cycling enthusiast, or semi-professional where the smallest margins make all the difference.

This is undoubtedly a premium product, and although power meters have been coming down in price year after year, the Sram Red still sits at over a grand which is a lot of money. However, if you're able to afford it and want the absolute top of the line, this is the one to go for.

If you're looking for an easy do it yourself option that doesn't require you to take your bike apart, you might want to consider the Avio PowerSense. Rather than replacing the crank itself, you attach it to the one already on your bike.

While it is compatible with a large number of Shimano cranks, and will also work with some other brands too, it may not be as accurate as other power meters on the market. As a budget option, however, it is well worth considering.
