Power meter pedals are probably the most versatile option out there for recording your watts. The beauty of a pedal based power meter is that you can quickly and easily swap them from one bike to the next – usually in exactly the same way as you would a standard set of road pedals. We’ve selected the cheapest deal currently available for each model of pedal based power meter below:
Best price for left side only power meter pedals
Left side only power meters are the most budget friendly option. By measuring the power output of your left leg and doubling it, you get a fairly accurate representation of your overall power. Single sided power meters won;t tell you if you have an imbalance in the amount of power each leg is producing, but realistically it’s not the most useful information anyway! If you do decide you want to go dual sided later on, you can always add a right sided upgrade pedal (see below). For now, we’ve rounded up the best left side only pedal based power meters below:
| Retailer | Groupset | Price | Buy |
|---|---|---|---|
 | PowerTap P1S left side only | £323.99 | Buy |
 | Garmin Vector 3S left side only | £395.99 | Buy |

Best price for dual sided power meter pedals
Dual sided power meter pedals offer the most accurate power measurement, by recording the watts from both legs individually. This allows you to see if there’s an imbalance between the amount of power your left and right legs are generating. Though what you might do with that information we do wonder! Ultimately it means that the overall power measurement is more accurate than a left side only power meter. So if you’re a data junkie and budget allows, it’s a no brainer!
