Magene P715 Review: Dual-Sided Watts for Less, Pods and All

Dual-sided power pedals have had a price floor for years. If you wanted a meter in each pedal, measuring each leg independently rather than doubling one of them, you paid for the privilege — and the cheapest honest way in was a Favero Assioma Duo. The Magene P715, launched in mid-2025, is the first credible attempt to put that floor lower.

It is a dual-sided pedal meter claiming ±1%, in a Shimano SPD-SL version (the P715 S) and a Look Keo version (the P715 K), with a rechargeable battery Magene rates at 120 hours. That battery figure is more than double what Favero publishes for the Assioma Duo and a third more than Garmin's stated 90 hours on the current Rally 210. On paper it undercuts everything and loses to nothing.

On the bike, the picture is more interesting than that, and the sticking point is not the number the pedals report. It is the pods they report it from, and how thin the independent testing record still is by the standards of this category.

We have not ridden a set on our own bikes for this review. Every specification below comes from Magene's own product page or a US retailer listing, and every accuracy finding is attributed to the reviewer who measured it. Our how we review page explains why we work that way rather than pretending to a test lab we do not have.

What the P715 actually is

A pair of clipless road pedals with a strain gauge and a battery in each one, so both legs are measured rather than one leg being measured and doubled. Magene publishes ±1% accuracy across a 0-2,500 W power range and a 20-240 rpm cadence range, with active temperature compensation, an IPX7 water rating and an operating range of -20 to 50 °C.

The two versions differ only at the cleat. The P715 Ktakes Look Keo cleats, weighs 157 g a pedal and has an 11 mm stack. The P715 Stakes Shimano SPD-SL cleats, weighs 159 g and stacks 13 mm. Both share a 55 mm Q-factor. There is no off-road SPD version — Magene lists K and S only, so if you want power in a mountain bike pedal this is not the product, and our Assioma Pro MX review covers the pedal that is.

Charging is magnetic, using a cable that clips onto contacts on each pod, and Magene quotes about three hours from a 140 mAh cell. Data goes out over ANT+ and Bluetooth, though Magene's specification lists a single Bluetooth connection at a time alongside unlimited ANT+ connections — worth knowing if you routinely pair a phone and a head unit at once. Beyond power and cadence it reports left/right balance, torque effectiveness, pedaling smoothness, power phase and riding position, with the full set surfacing on Garmin head units and a subset elsewhere. It does not report Platform Center Offset, which the5krunner flagged as a gap against the Favero and Garmin competition.

The pods are the design decision that defines it

Every reviewer lands on the same visual point, so it is worth being plain about it. The P715 carries its battery and electronics in housings that sit on the spindle between the crank arm and the pedal body — the same arrangement the Favero Assioma Uno and Duo have always used, and the one Favero specifically engineered out of its Pro range by sealing everything inside the axle. GPLama named the external pod design as one of the reasons the P715 is a harder sell than it looks.

In practice the pods do two things. They set the Q-factor, which at 55 mm is a couple of millimeters wider than Favero's current pedals — a difference most riders will not feel but some will want to compensate for at the saddle. And they create a clearance question with your shoe. The5krunner noted the P715's pod diameter is smaller than the ones that used to cause shoe rubbing, which is a real improvement, but a pod is still a pod.

The thing they do not do is make the measurement worse. Pods are an aesthetic and packaging compromise, not an accuracy one. If the look does not bother you, this is the cheapest complaint on the list to live with.

Accuracy: what four independent testers actually found

This is where an honest review has to resist tidying things up, because the published findings do not all agree.

GPLama reviewed the SPD-SL version in April 2026 and concluded that it delivers solid, within-spec power data and performs well as a pedal, with good battery life and durability. His reservations were about the external pods, the limited feature set and the price relative to stronger alternatives — not the numbers.

Cyclists Hub tested a Keo pair indoors against a Wahoo Kickr v5 and measured the pedals consistently low: 2.8% below on an interval session, 2.1% on a free ride and 2.5% on a race, with maximum-power readings 4.8% to 6.2% below the trainer, and cadence over-reported by 1.3% to 1.7%. They were careful to say a third power source would be needed to confirm which device is the one that is off. Their weighted overall score was 4.6 out of 5, and they called the P715 a worthy and more affordable contender.

the5krunnerpublished a first-look review in July 2025 with seven comparison rides. Against a 4iiii crank arm he saw about a 5% overall difference, which he called more than he would expect; against Magene's own P505 crankset the gap was around 4%, which he called too much; and against a pair of Kickr trainers the pedals sat, in his words, nicely in the middle of the watt range. His verdict was conditional: a winner only if the accuracy and stats hold up.

Cycle Tech Reviewpublished a preview covering the specification, the gyroscope-assisted power calculation and Magene's claim of one-million-cycle durability testing, but did not publish comparative accuracy data.

Read together, the picture is not alarming, but it is not settled either. The most recent and most systematic testing — GPLama's, nine months after the first-look reviews and presumably on more mature firmware — found the pedals within spec. The offsets other reviewers measured were consistent rather than drifting, and a consistent offset is far less damaging to training than a wandering one: your zones are set from a test done on the same meter, so a stable bias largely cancels out. What it does break is comparing your numbers to a friend's, or to a trainer you also ride. If that matters to you, pick one device as your reference and calibrate properly before every session that counts.

Battery life is the spec that genuinely wins

Magene states 120 hours per charge. That is a real advantage and the easiest one to verify from published figures: Favero publishes 50-plus hours for the Assioma Duo, Garmin publishes up to 90 for the Rally 210. Only the Assioma Pro RS beats it, at up to 160 hours since Favero's February 2026 firmware update — and that pedal costs considerably more.

In practical terms, 120 hours is most of a winter of indoor training before you think about a charger. Charging is magnetic and takes around three hours from empty, which means the sensible routine is to charge both pedals overnight once a season rather than to worry about it. There is no coin cell to buy, no battery door to cross-thread and no compartment to flood.

Fitting, the app and what is in the box

The pedals thread into standard cranks and fit with an 8 mm hex wrench. Magene advertises a one-minute installation; the5krunner put the real job at two to three minutes, which is about right for anything you have to torque properly. Crank length is set in the Magene Utility app or on the head unit, and it matters — get it wrong and every watt is wrong by the same proportion. The app handles firmware updates and both automatic and manual calibration, and Cyclists Hub described the automatic zero-offset behavior as set-and-forget. The5krunner was less enthusiastic, saying the app is not as clean as Favero's but works.

Cleats are not included. Magene lists the box as two pedals, two crank washers, a charging cable and a quick start guide, and Power Meter City states plainly that the manufacturer does not supply cleats. Both Favero and Garmin do. Budget accordingly, because a set of cleats is a meaningful fraction of the gap between the Magene and the competition, and Cyclists Hub found clipping in harder with the third-party cleats they used.

Two more figures worth knowing, both from Power Meter City's US listing rather than Magene's own page: a 264 lb rider weight limit and a two-year warranty. Magene does not publish a crank-thickness limit the way Favero does, so if you run unusual cranks or have ever needed a pedal washer to clear a crank arm, ask before you order.

Where it sits against the alternatives

Against the Assioma Duo, the Magene wins on price and battery life and loses on weight and record. Both carry pods; both claim ±1%. The Duo has been compared publicly against more reference meters than almost any power meter on the market, and that track record is what the price difference buys.

Against the Assioma Pro RS-2, the Magene wins on price and nothing else. The Favero is lighter by a wide margin, pod-free, sealed, longer-running, supplied with cleats, and its body swaps to another cleat system. It is also in a different price bracket. The5krunner noted in his verdict that Favero had matched the P715's launch price, which removed the price advantage that was the Magene's whole argument — so check both live prices in the table above rather than trusting any published figure, including this paragraph.

Against the Garmin Rally RS210, the Magene wins on price and battery and loses on weight, build and ecosystem integration. The Rally's convertible bodies are its real structural advantage: one spindle covers SPD-SL, Keo and off-road SPD. The P715 covers two road cleat systems and asks you to choose at checkout. Our Assioma vs Rally comparison covers that rivalry in full.

And against Magene's own PES P505 crankset, the pedals win on portability and on the tolerance Magene publishes, while the crankset wins on price. That is the same fork the whole category runs on, and our power meter pedal roundup and crank power meter roundup take the two sides of it.

Who should buy it

Buy the P715 if dual-sided measurement matters to you and the Assioma Duo is out of budget, if you ride SPD-SL and do not want to pay Pro RS or Rally money to keep your cleats, or if long battery life between charges is the thing you actually care about. Those are good reasons, and the pedals answer all three.

Skip it if the pods will bother you every time you look down, if you need a pedal that also goes off-road, if you want the longest possible record of independent verification behind the number, or if you would be comparing your watts directly against a training partner's and cannot tolerate an unresolved offset. And if you do not own a smart trainer yet, buy the trainer first — it measures power indoors on its own, which makes a pedal meter the second purchase rather than the first. Our smart trainer vs power meter guide walks through that order properly.
