How to Choose a Power Meter in the UK - Buying Guide

When looking for a power meter, there are a number of things to consider when determining which will be the best for you. You'll need to think about where they are placed on the bike itself, how accurate you want the readings to be, and how you can actually access and read your data. Here's what you need to know!

1

Different Types of Power Meter Offer Different Benefits to the User

There are a few different types of power meter available on the market today. Although all use what’s called a strain gauge in order to measure force, and therefore your performance on a bike, each type of power meter offers unique benefits. 

Pedal and Crank Based Power Meters Are Easy to Fit

Pedal and Crank Based Power Meters Are Easy to Fit

If you’re looking for something easy to add to your bike, a pedal or crank based power meter is the best way to go. While we’re sure we don’t need to explain to you what a pedal is, the crank is the part of the bike that the pedal attaches to. Fitting one of these meters is as simple as replacing the current crank or pedal with the power meter.


Pedal and crank based power meters can be slightly less accurate than other options, but are a great choice when used as a pair to compare performance between both legs. The big difference between the two is that pedals measure force applied at the point of contact, whereas crank based measures torque.

Hub-Based Power Meters Are Accurate and Reliable

As the hub-based power meter sits in the back wheel of your bike, there are far less forces acting on the strain gauge, making it extremely accurate and reliable when it comes to measuring your power. However, you can expect a slight difference in readings when compared to crank and pedal based meters as the force at the wheel is slightly lower than at the crank.


When it comes to hub power meters, it is extremely important to make sure your back wheel is compatible with the hub you buy. There are also some wheels on the market with inbuilt power meters which are worth considering but, again, you'll need to ensure they’re the right size for your bike.

Bottom Bracket and Chainring Meters Are Low Maintenance, but Difficult to Fit

Bottom Bracket and Chainring Meters Are Low Maintenance, but Difficult to Fit

These power meters are located where the pedals and crank attach to the bike. The chainring is where the bike chain sits, and the bottom bracket is what allows it to turn. While these meters are very accurate and require little maintenance, they can be a pain to fit.


While most meters require only a fundamental knowledge of bike maintenance to attach, these are a choice more suited to the experienced bike mechanic. There are also a large number of bracket and chainring sizes, so it can be easy to get the wrong one if you aren't confident in your ability.

2

Make Sure It's the Correct Size for Your Bike

Make Sure It's the Correct Size for Your Bike

When it comes to bikes, there aren’t many universal sizes, so it is always worth checking the measurements. Even pedals, which are one of the easiest things to change, aren’t one size fits all. There are too many different component sizes to list, but it is important that any power meter specifications match those of your bike.


Although we’re confident that those considering purchasing a power meter will be more than knowledgeable about bikes and cycling, there are a number of difficulties you could come across.  This is why we need to stress that a working knowledge of bike maintenance and assembly is required when fitting a power meter.


While most cyclists will be comfortable changing pedals and the like, if you're not comfortable with changing gears, wheels, or chains, you should consider seeking professional help as many bike mechanics will be able to fit a power meter you have purchased for a small fee.

Check That You Have a Compatible Cycling Computer or Smartphone App to Check Your Data

Check That You Have a Compatible Cycling Computer or Smartphone App to Check Your Data

Most power meters on the market transfer data using ANT+, a wireless technology used for health and fitness monitoring, which will be compatible with nearly all cycling computers on the market. Although, some can also use Bluetooth technology in order to transmit your data between devices. 


If you’re serious about cycling, we would recommend investing in a cycling computer. However, if you’re working on a budget, there are a number of apps on the market which will allow you to check your data in real time on a smartphone or watch


That said, it is always worth double checking an app is compatible with your hardware before buying. If you're not sure where to start, something like the Garmin Connect App will work with most power meters on the market.

4

Keep an Eye on Battery Life

Keep an Eye on Battery Life

Although many power meters look mechanical, they are portable electronic devices which record and transmit data, meaning that they require batteries to operate. The good news is that the battery only drains when you're actually cycling, so there's no need to worry about it going flat while locked away in a garage.


Most power meters will use a coin cell battery, similar to the ones found in watches and other small electronics. These batteries usually claim around 300 hours of life. However, this tends to be an optimistic estimate. Thankfully, you'll be able to keep an eye on the battery level of your power meter through whichever app or cycling computer you're using to monitor your data.

The Best Power Meter for Accurate Readings

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.

A Great Entry Point

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.

Great Accuracy and Precision Without the Added Weight

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.

A Stylish and Affordable Dual Crank Meter

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.

A Cheap Yet Balanced Power Meter

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.

A Premium Option at a Premium Price

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.

A Cheap but Effective DIY Option

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.

What Is a Power Meter?

What Is a Power Meter?

Power meters are a confusing piece of equipment, and the many different types on the market only adds to that uncertainty. In simple terms, power meters measure the amount of force you’re applying over distance and wirelessly transmits the information to a cycling computer or a smartphone app.


Different power meters measure force in varying ways, depending on where the meter is located on your bike. For example, ones placed on the back wheel will only measure the power generated by that specific wheel, whereas ones placed on the pedals or crankshaft will measure the force applied by the cyclist directly.

Summary

If you're looking to get the absolute best performance you can while cycling, it's well worth considering picking up a power meter. They're a sound investment for cyclists, especially if you're serious about the sport. We hope after reading this article, you've been able to find one that fits your needs, and your bike!
