Of the three places a power meter can live, the pedals are the ones that win on the thing most riders underrate: portability. A pedal meter unbolts with a wrench and follows you onto your winter trainer bike, your travel bike, or next year's frame — no reinstall, no new purchase. If you own more than one bike, that alone is usually enough to settle the type question. For the wider view across crank and spider meters too, see our best power meters roundup.
Why pedals win on transferability
A crank-arm or spider meter is bolted to one bike from the day you fit it. A pedal meter is just a pair of pedals: five minutes with a pedal wrench and it's on a different bike, reading the same watts. For an upgrading rider with a road bike, a gravel bike and a dedicated trainer bike, one pedal meter can serve all three — which quietly makes it the cheapest option per bike even when the sticker looks higher than a single-sided crank meter. It also means the meter outlives the frame: your bike changes, your power data doesn't reset.
Cleat-system compatibility is the real decision
Here's the catch that trips people up: a power pedal replaces your pedal, so it also dictates your cleat. Buy the wrong system and you're buying new shoes-worth of cleats too. The Favero Assioma uses a Look Keo-compatible cleat. Garmin's Rally line lets you choose: RS for Shimano SPD-SL, RK for Look Keo, XC for SPD mountain — and the spindles convert between them later. The Wahoo Powrlink Zerois the only power pedal built on the Speedplay platform. Match the meter to the cleat you already ride and setup is painless; ignore it and you've created a project.
Single-sided vs dual-sided
A dual-sided pedal set reads each leg independently and reports true left-right balance. A single-sidedset instruments one pedal — the left — and doubles it. For most riders on a structured plan, single-sided is genuinely enough: the number is repeatable, and repeatability is what your training zones depend on. Dual-sided earns its premium if you're rehabbing an imbalance, chasing efficiency, or you just want the full picture. Favero's Assioma line lets you split the difference — start with the single-sided Uno and add the second pedal later.
How we ranked them
We don't run a test lab, and we say so plainly on our how we reviewpage. What we did instead: pulled the manufacturer spec sheet for every pedal, recorded the cleat system, claimed accuracy, battery type and single- or dual-sided measurement, then scored each on accuracy, transferability, data depth and value. Favero, Garmin and Wahoo all publish a claimed ±1%, so cleat fit and battery style do most of the deciding. Prices pull live from Amazon, so you'll see today's number or "Check price," never a stale one.
| Power pedal | Cleat system | Sided | Claimed accuracy | Battery | Best for |
|---|---|---|---|---|---|
| Favero Assioma Duo | Look Keo compatible | Dual | ±1% | Rechargeable | Overall |
| Garmin Rally RS200 | Shimano SPD-SL | Dual | ±1% | Coin cell | Road cleats |
| Garmin Rally RK200 | Look Keo | Dual | ±1% | Coin cell | Look Keo |
| Wahoo Powrlink Zero | Speedplay | Dual | ±1% | Rechargeable | Speedplay |
| Favero Assioma Uno | Look Keo compatible | Single (left) | ±1% | Rechargeable | Value |
What actually matters when you're buying pedals
Cleat fit first, accuracy second. Every pedal here claims ±1%, so the headline accuracy figure barely separates them — the cleat system and how the battery works will shape your daily experience far more. Get the cleat right and the rest is detail.
Battery styleis the other quiet differentiator. The Favero and Wahoo pedals recharge; the Garmin Rally runs on replaceable coin cells. Rechargeable means no drawer full of cells, but a dead battery mid-trip needs a charger rather than a corner-store swap — pick the trade you'd rather live with. Whatever you choose, a pedal meter pairs with the rest of the pain cave over Bluetooth and ANT+, so read our smart trainer vs power meterguide if you're deciding which upgrade to buy first.

Every pick, in detail
#1 · Best overall pedals
Favero Assioma Duo
9.39.3 out of 10
#ad We may earn a commission · Price as of July 23, 2026
The dual-sided pedal we'd hand most upgrading riders — accurate, rechargeable, and it moves between bikes fast.
- Cleat system
- Look Keo compatible
- Sided
- Dual-sided
- Claimed accuracy
- ±1%
- Battery
- Rechargeable (~50 hr)
- Connectivity
- BT, ANT+
- Weather
- IP67 rated
What we'd praise
- Rechargeable battery — no coin cells to keep in a drawer
- Claimed ±1% dual-sided accuracy at a sensible price
- Swaps to any bike with a Look Keo-style setup in minutes
What we'd flag
- Locks you into a Look Keo-compatible cleat
- Taller stack height than a bare road pedal
If you ride a Look Keo-style cleat, the Assioma Duo is the pedal meter to beat. It reads both legs at a claimed ±1%, recharges over a magnetic clip instead of eating coin cells, and unbolts to follow you onto a second bike or the trainer bike in the time it takes to swap pedals. Favero rates the pods to IP67, so bad weather isn't a worry.
There isn't a weak spot here for the price. The only real question is whether you need dual-sided at all — if you don't, the single-sided Assioma Uno saves money and upgrades later. The full breakdown is in our Assioma Duo review.
#2 · Best for road cleats
Garmin Rally RS200
8.98.9 out of 10
The dual-sided pick for riders who want to stay on Shimano SPD-SL road cleats.
- Cleat system
- Shimano SPD-SL
- Sided
- Dual-sided
- Claimed accuracy
- ±1%
- Battery
- Coin cell (LR44)
- Connectivity
- BT, ANT+
- Convertible
- To Look Keo or SPD
What we'd praise
- The only pedal meter that keeps you on Shimano SPD-SL cleats
- Dual-sided with full Cycling Dynamics on Garmin head units
- Spindles convert to a different cleat system later
What we'd flag
- Runs on coin cells rather than a rechargeable pack
- Priced above the Assioma for comparable accuracy
Most power meter pedals force a Look Keo-style cleat on you. The Rally RS200 is the answer for riders committed to Shimano SPD-SL road cleats — the same shoes and cleats you already ride, now measuring dual-sided power at a claimed ±1%. On a Garmin head unit it adds Cycling Dynamics, the deepest pedaling-data layer any pedal here offers.
It runs on replaceable coin cells rather than a rechargeable pack, and it sits above the Assioma on price. But if SPD-SL is non-negotiable, it's the clear pick — and Garmin's conversion kits mean the spindles can become Look Keo (RK) or SPD (XC) pedals if your cleat loyalty ever changes.
#3 · Best for Look Keo
Garmin Rally RK200
8.98.9 out of 10
#ad We may earn a commission · Price as of July 23, 2026
The dual-sided Look Keo option with Garmin's data depth and convertible spindles.
- Cleat system
- Look Keo
- Sided
- Dual-sided
- Claimed accuracy
- ±1%
- Battery
- Coin cell (LR44)
- Connectivity
- BT, ANT+
- Convertible
- To SPD-SL or SPD
What we'd praise
- True Look Keo cleat rather than a compatible copy
- Dual-sided with Garmin Cycling Dynamics
- Convertible spindles for a future cleat change
What we'd flag
- Coin cells instead of a rechargeable battery
- Carries the Garmin premium over the Assioma
The RK200 is the Rally in genuine Look Keo trim — the same pedal body Look riders already know, with dual-sided measurement and a claimed ±1% baked into the spindles. It's the natural pick for a rider who wants Keo cleats and Garmin's Cycling Dynamics in one package rather than a Look Keo-compatible clone.
Like the SPD-SL version, it trades a rechargeable pack for coin cells and sits at the top of the price band. The upside is the same convertibility: buy the pedal-body kit and the RK spindles become SPD-SL or SPD pedals down the road, so a cleat change never means buying a new meter.
#4 · Best for Speedplay
Wahoo Powrlink Zero
8.68.6 out of 10The pick for Speedplay loyalists who want power without giving up dual-sided entry and float.
- Cleat system
- Speedplay (Wahoo)
- Sided
- Dual-sided
- Claimed accuracy
- ±1%
- Battery
- Rechargeable (~75 hr)
- Connectivity
- BT, ANT+
- Float
- Adjustable, dual-entry
What we'd praise
- The only power pedal built on the Speedplay platform
- Rechargeable, claimed ±1%, and dual-sided
- Dual-sided entry and adjustable float Speedplay riders swear by
What we'd flag
- Only worth it if you specifically want Speedplay
- Cleat hardware and shims add setup fuss over other systems
Speedplay riders used to be locked out of pedal-based power entirely. The Powrlink Zero fixed that: it's a genuine Speedplay pedal with dual-sided measurement at a claimed ±1% and a rechargeable battery, so you keep the dual-entry and adjustable float that make Speedplay riders loyal in the first place.
It only makes sense if Speedplay is what you want — there's no accuracy reason to pick it over the Assioma otherwise, and the cleat hardware is fussier to set up. But for a committed Speedplay rider, it's the one pedal meter that doesn't ask you to abandon your cleat system.
#5 · Best single-sided value
Favero Assioma Uno
8.88.8 out of 10
#ad We may earn a commission · Price as of July 23, 2026
The value pedal meter: the Duo's accuracy and portability, single-sided, with a clean upgrade path.
- Cleat system
- Look Keo compatible
- Sided
- Single (left)
- Claimed accuracy
- ±1%
- Battery
- Rechargeable (~50 hr)
- Connectivity
- BT, ANT+
- Upgrade
- Add right pedal → Duo
What we'd praise
- Same claimed ±1% and rechargeable body as the Duo for less
- Moves between bikes just like the dual-sided version
- Upgrade to a full Duo later by adding the right pedal
What we'd flag
- Single-sided — no true left/right balance
- Still tied to a Look Keo-style cleat
The Uno is the Duo with one instrumented pedal instead of two. Same claimed ±1%, same rechargeable battery, same swap-to-any-bike convenience — for meaningfully less. It reads your left leg and doubles it, which is enough for most riders to train by power honestly.
The clever part is the upgrade path: add the right-side instrumented pedal whenever you like and the Uno becomes a full Duo, nothing wasted. If you're weighing single against dual, our Duo vs Uno comparison makes the call clear.
Good questions
Frequently asked questions
Do power meter pedals fit any bike?
Mechanically, almost any modern bike — they thread into standard crank arms and swap in about five minutes with a pedal wrench. The real compatibility question is your cleat: a power pedal replaces your pedal, so it dictates the cleat system your shoes use. Match the pedal to the cleat you already ride (or plan to switch to) and it fits your whole stable.
Which cleat system should I choose?
Buy the power pedal that matches the cleat you already ride so you don't have to replace shoes and cleats. Favero Assioma uses a Look Keo-compatible cleat, the Garmin Rally comes in Shimano SPD-SL (RS), Look Keo (RK) and SPD (XC) versions, and the Wahoo Powrlink Zero is the only Speedplay option. If you're starting fresh, Look Keo-compatible is the most flexible and widely supported.
Are single-sided pedals accurate enough?
For training by power and setting zones, yes. A single-sided pedal reads your left leg and doubles it, and because that figure is repeatable ride to ride, your zones stay valid. Step up to dual-sided if you want true left-right balance data, are returning from injury, or are working on pedaling efficiency.
Rechargeable or coin-cell battery — does it matter?
It's a lifestyle choice, not an accuracy one. Rechargeable pedals like the Favero Assioma and Wahoo Powrlink Zero mean no coin cells to buy, but a flat battery mid-trip needs a charger. Coin-cell pedals like the Garmin Rally can be revived with a cell from any store but ask you to keep spares. Both hold their accuracy claim the same way.
Will power pedals work with Zwift and my bike computer?
Yes. Every pedal here broadcasts over Bluetooth and ANT+, so it pairs with Zwift, your bike computer and training apps just like a smart trainer. Indoors on a smart trainer you can even use the pedals as your primary power source for consistent numbers across indoor and outdoor rides.
