power2max NGeco ROTOR 3D+ 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 ROTOR 3D+ 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 $490!



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 110 4-Bolt Shimano BCD in order to fit your choice of chainring sizes.

Note – The 110 4-Bolt Shimano BCD version is compatible with Shimano Ultegra 8100 and DURA-ACE 9200 chainrings.

Lock Ring Tool: This page also allows you to purchase your power meter with the power2max Lock Ring Tool for ROTOR, which is required for installation. We recommend you order it unless you already own one. Note the tool is 50% off when you bundle it with a power meter on this page.

    Josh was great! He helped me through the whole buying process and emailed me personalized videos explaining all I needed to know to install the POWER2MAX NGECO ROTOR 3D+ ROAD POWER METER. He made sure I had all the tools too. The installation went smoothly. I just took my first ride. The power meter worked great!

    I highly recommend Power Meter City and Josh.

    Thanks Josh!

    I chose power2max NGeco as my first power meter based on information provided on Power Meter City’s website. My shipment arrived fast with everything needed to install. Installation took less than 15 minutes, including syncing with my Garmin 1030. The unit works great. I will continue to upgrade my bikes with power2max power meters purchased from Power Meter City in the future. Thank you for the great service.

    Looking for a power meter, I ran across this on the Powermetercity website. Two days later, I had it in my hands. I paired it up to a Wahoo Element Bolt, and it synced up right away. I had the meter installed on my bike, and took my first ride with it. It is very accurate, and looks great on the bike. Highly recommend the meter and Powermetercity.

    Great product and works just as expected. I’ve run this product against smart trainers and the data analysis comparisons are fantastic!! And all of this at a great price!!

      Hi Billy. Glad to hear you liked your p2m NGeco ROTOR 3D+. Those are really good power meter. We hope you continue to enjoy them and let us know if there is anything else we can do.

    Was planning on buying the Vector 3 or the Favero Assioma, I don’t regret buying NGeco, it has been providing constant power/cadence reading without any problems for half the price of the pedals. I have a Garmin Edge 1030 and it synced up instantly. The best part of the device is if you need anything else (left/right balance or pedal smoothness) you can upgrade the firmware through you app. With 2 year of warranty you can’t ask for anything else. Highly recommended!

      Hi Melvin. It’s great to hear your p2m NGeco ROTOR 3D+ is working out for you. They are such nice power meters – simple, reliable and accurate. Keep up the good work!
