The Arofly power meter debuted a little over a year ago, but that iteration required you to use their own GPS cycling computer to work. Which is a tough sell even if you are offering the world’s smallest, easiest to install power meter. Their sensor attaches to your rear tire’s valve stem and uses pressure differentials to just measure power, relying on the head unit’s GPS to tell it how fast you’re going and other data. Then it puts all that together to determine your total power.
Now, they’ve added an ANT+ / Bluetooth brain unit to liaison communications between the sensor and any modern GPS cycling computer, letting you use it with your Garmin, Wahoo, etc. It uses your rider profile data (mainly just your weight) that’s input into those cycling computers to be able to give you the correct power output numbers. So, regardless of whether you buy into their full ecosystem or wait for this new version to come out next year, you’ll need to make sure you’re keeping your body weight up to date in your chosen computer. As long as you’re doing that, they say it works for road and mountain bikes.
The unit also has built-in accelerometer and gravity sensors, which let it determine cadence without any additional sensors strapped to your bike. Pricing and availability for the new package is TBD. Considering the current version is $269 with the computer, expect it to be one of the most affordable power meters when it does hit.
