power2max NGeco Praxis Road Power Meter

The NGeco is the newest model in the power2max line-up. With features such as dual leg power measurement, ANT+/Bluetooth SMART compatibility and left/right power balance, the power2max NGeco Praxis Road Power Meter comes fully-loaded. In addition, the NGeco is accurate to +/- 2.0% in all environmental conditions and is easy to use with features such as auto-zero and accelerometer-based cadence measurement. In fact, there is no other power meter that provides dual-leg power measurement plus these other features at only $590!



Dual-Leg Power Measurement

The NGeco power meter measures power at the crank spider. This means it measures both left and right leg power.

Accurate to +/- 2.0%

The power2max is always consistent and accurate, regardless of the environmental conditions.

Long Battery Life

The power meter gets 300-400 hours of run time off of a single CR2450, user-replaceable battery.

Left/Right Power Balance

In addition to measuring both legs, the NGeco can also provide left/right power balance with a system upgrade.


Featuring both ANT+ and Bluetooth SMART, the power meter can be used with virtually any bike computer or smart phone.


With the auto-zero feature, you never have to worry about manually calibrating the unit. Just get on and go!


BCD: This power meter is available in either a 110 or 130 BCD in order to fit your choice of chainring sizes.

Upgraded NG Version: While the NGeco you are viewing on this page is our go-to version for most cyclists, please note we also have the upgraded power2max NG Praxis Road Power Meter. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics.


Tools Needed for Installation

You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.

  • T25 Torx bit
  • 8 mm Allen key


Crankset: The power2max NGeco Praxis Road Power Meter is compatible with Praxis direct mount cranksets. Direct mount cranksets (left image) have drive-side crank arms that can be removed from the crankset. In addition, if you were to view the backside of the crank, you would see three small bolts or screws that secure the crank arm to the spider or chainring.

Standard cranksets (right image) have a one-piece drive-side crank arm and spider. That is, the crank arm and spider are one solid piece of aluminum.

Most modern Praxis cranksets are direct mount. This includes Zayante M30, Alba M30 and Zayante Carbon M30. It's very important you confirm you have a direct mount version where the drive-side crank arm can be removed. If you are not sure, please send us some images of your crankset and we would be happy to confirm for you.

Praxis Direct Mount vs. Standard Crankset

Chainrings: This power meter is compatible with 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt (Shimano) chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

Note 1 - Please note, the 110 BCD 4-Bolt (Shimano) version is compatible with all Shimano 4-bolt chainrings, including Ultegra 8100 and DURA-ACE 9200 chainrings.

Note 2 - Some Praxis cranksets come equipped with direct mount chainrings. In this case, you will need to purchase new chainrings as direct mount chainrings won't work with a power meter spider. We have several chainrings to choose from on our Chainrings page.

Note 3 - This power meter is not compatible with Praxis 48/32 chainrings.

What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.

*Power Balance Upgrade

The power2max NGeco measures power from both legs right out of the box. However, with power balance, you are able to see how much power each leg is generating individually. If this information is important to you, you can choose to upgrade the power meter at any time. (Please note, you can also purchase the NG version of the power2max which comes with this feature unlocked, along with a rechargeable battery and a longer 5-year warranty.)

You can upgrade your NGeco using the power2max app once you receive the power meter. The cost to upgrade is 50 euros.

  1. Avonlea Haymart (verified owner)

    When I bought this power meter, I received an email pretty quickly from one of the people from power meter city. He wanted to check in to see that I had the direct mount Praxis crankset. I thought I did, and I sent him a picture, and he let me know that I actually didn’t. So we sent some email back and forth; I asked him lots of questions about the crankset, chainrings, etc, and he helped answer my questions quickly, and even with some videos. Thanks to his help, I found out what exactly what I needed to buy to make it compatible. I bought the new generation of Praxis alba crankset, and I was able to use my original bcd110 chainrings from the original crankset for compatibility with the power meter.

    The power meter itself is great, I’ve had it installed for a few weeks now and have used it in rain and shine. Works well with my Bryton 420, power and cadence both. And they let you choose which color power meter you want, so it adds extra color to the bike 🙂

    First a shout out to PMC and their excellent customer service! The power2max showed up quickly with the chain ring already installed which was nice. The power meter itself was very easy to install on my Diverge EVO.

    Couple of things. The iPhone app for this power meter seems to be very problematic. Using the app is not mandatory though. I initially had trouble getting it to work with my Garmin however I discovered I had added a Bluetooth connection instead of an ANT+ connection. Once I did that the Garmin worked flawlessly. On the test ride the power and cadence worked great. No apparent drop outs.

    Overall the unit appears to be very solid. It was easy to install and connect to my Garmin (my mistake by not verify ANT+ ). Power numbers seem to being inline with what I expected. At this point I’m very satisfied.

    And of course thanks to PMC for their great customer service.

    Excellent power spider to go on my gravel rig. PMC pre-fitted my Praxis 1x ring and all I had to do was install my cranks and go! Ordering was very easy and product arrived in a very timely manner. Very happy and will definitely order from PMC again!

    • Power Meter City

      Thanks for this Daniel, really appreciate it. We are looking forward to it. If there is anything else we can do, please let us know! Ride safe!

    10 minute install, works flawless! Have it on my Rodeo Labs Trail Donkey, and it works perfectly!

    • Power Meter City

      Great job Eric! Thanks for this awesome review! We hope you will continue to enjoy them and please let us know if there is anything else we can do! Ride safe!

  5. surly singlespeed (verified owner)

    This thing is great! I have previously used a Powertap hub and SRM crank based power meters and this works equally as well and has the best appearance to boot. It starts and connects quickly and is very accurate.
    I would add the the service is great too. I ordered with a chaining and bolts, all of which was installed and ready to go. I had it mounted in 15 minutes.
    This will be where I get a PM for my mountain bike.

  6. TXCLG (verified owner)

    First power meter from Power2Max and I’m very happy with it for the few rides that I’ve used it on. The crank based power meter was easy to install and quick to setup with my Garmin. Install is very simple with just the three bolt to attach to the crank and then the bolts to mount the chainring. Did a 52 mile ride in the heat and power really helps keep you in the right zone and not over or under perform. Great service from Power Meter City as well!

    • Power Meter City

  7. Robert Willcox (verified owner)

    This is my second Ngeco power meter from Power Meter City. I have one on each of my two Crux (CX). One is a Sram CX 1 and the other is for a Praxis carbon crankset. I have been very happy w both of them. There have been no problems over the 4 months i’ve been using them several times a week. Im very happy w the accuracy as well. It tracks very closely w the dual crank based power meter on my road bike. Im very satisfied w the German engineered PM and the service provided by Power Meter City.
