Best Power Meters for under £600

The number of entry-level power meters on the market has soared in recent years, manufacturers are now offering a range of hub, crank and pedal-based systems. With so many affordable options available you’ll be forgiven for thinking “which is the best power meter for me?”

Firstly, what is a power meter and how does it work? Cycling power meters measure the power output of a rider and transmit the data to a head unit, i.e. your Garmin, Lezyne or Polar cycle computer. The majority of cycling power meters use strain gauges to measure the torque applied and when combined with angular velocity, calculate power. Simply put, they measure the force put through the pedals and multiply it by cadence to calculate power, which is measured in watts.

Training with power is the most accurate way to give an objective measurement of your effort. Traditional training approaches such as using a heart rate monitor or simply ‘perceived effort’ can be heavily influenced by a number of external factors such as fatigue and adrenaline. Power meters allow you to accurately define your training zones and work within them, whether you’re a professional training for a race, or an amateur working towards a sportive. The number of manufacturers producing power meters has risen massively over the past few years, many of which offer a range of entry-level models.

Below are six of the best power meters for under £600.

The 4iiii is the world’s lightest left side power meter, it boasts a highly impressive accuracy reading of +/- 1% and has a built-in adjustment scale factor to account for leg imbalances. ANT+ and smartphone compatibility help you optimise your training and work with your device of choice, while improved battery life and a battery status indicator improve reliability. Delivering the same level of accuracy as a number of high-end models, at just a fraction of the price, the 4iiii sets a new benchmark for affordable power meters. Accuracy: +/- 1% Weight: 9 grams Battery life: 100 hours (CR2032)

The PowerPod measures, up to 800 times per second, the opposing forces caused by hills, wind, acceleration, and friction. Opposing forces matched identically by the forces applied by both legs, determine the cyclist’s power. The unit is attached to the handlebars meaning you can use any cranks, wheels or pedals and the device can quickly be switched between bikes. According to PowerPod, the V2’s accuracy is on a par with dual-sided crank-based systems and is superior to single-sided power meters. At less than £300 it’s an affordable solution to training with power if you have a limited budget. Accuracy: Difficult to calculate due to variables but when compared with SRM the V2 is +/- 3% accurate. Weight: 34 grams Battery life: 20 hours (USB rechargeable)

Pedal-based power meters have become extremely popular in recent years, partly due to their compatibility and versatility. The pedals can be easily changed between bikes and no bottom brackets converters or specific crank systems are required. Powertap has been manufacturing power meters for the last 17 years. They’re now offering a single-sided version of the world-renowned P1 pedals – at a fraction of the price. The Powertap P1S also touts the same plug-and-play installation, easy to swap, cross bike compatibility, along with dual-band ANT+ and Bluetooth as its bi-lateral counterpart. Accuracy: +/-1.5% Weight: 390 grams (per pair) Battery life: 60 hours (AAA Lithium)

The FSA PowerBox Alloy uses a Power2Max spider and is another affordable crank-based power meter, which provides a highly accurate total power output measurement of both legs. FSA’s alloy arms and BB386EVO spindle mated together produce a very lightweight, extremely versatile power meter crankset that can be fitted to any frame. UK Continental team OnePro Cycling use FSA PowerBox power meters on both their road and time trial bikes. Speaking with one of OnePro Cycling’s mechanics, he told me “The team had no issues whatsoever and only had to change the batteries one to two times all season (per unit), they’re reliable and work perfectly.” Accuracy: +/- 2% Weight: 751 grams Battery life: 400 hours (CR2450)
