If you are looking for a power meter for a Shimano crank arm, we would suggest a 4iiii or Stages crank arm power meter.

Introducing the all new WATTEAM POWERBEAT G3 Power Meter! WATTEAM continues to push the boundaries of what a power meter is capable of with its newest power meter – the POWERBEAT G3. If you are not already familiar with the POWERBEAT, it is the world’s first user-installed power meter with features, functionality and accuracy once found only in factory installed units.

The POWERBEAT attaches to the crank arms in a simple, 30-minute procedure requiring only basic technical skills. Once installed and calibrated, the POWERBEAT provides power data that is accurate to within +/- 1.5% – the industry standard. In addition, the WATTEAM POWERBEAT G3 Power Meter is extremely lightweight at only 35 grams per side, features a rechargeable battery with 60-hour life and offers both ANT+ as well as Bluetooth SMART compatibility.

Perhaps best yet, at $399, the POWERBEAT G3 Power Meter is the most affordable, direct force power meter capable of measuring independent left/right power.


What’s New with the G3

The new design of the G3 features several key upgrades. To begin with, the Comp Units now have a slide off feature whereby they can be quickly removed from the bracket, without having to take the entire housing off the pedal spindle. This allows you to easily move your Comp Units from bike to bike. You can also install a Dummy Comp Unit (supplied) for washing your bike or traveling. The G3 Comp Units also feature a housing that is both more aerodynamic as well as more robust, so as to withstand the rigors of outdoor abuse.

The POWERBEAT G3 app is also all new. In addition to assisting you in the installation of your POWERBEAT, the new app, available for both iOS and Android, turns any smart phone into a head unit. The app will record your ride data, has a built in coaching feature, will help you calculate and monitor your FTP and even emails you your ride file after each ride – among other new features.



At $399, the POWERBEAT Power Meter is the most affordable, direct force power meter capable of measuring independent left/right power.

Left/Right Power Balance

With sensors on both crank arms, the G3 can provide total as well as independent left/right power measurement.

Light Weight

The G3 is extremely lightweight. The entire system (Comp Unit and Sensor) only adds 35 grams to each crank arm.


The POWERBEAT is tested +/- 1.5% accurate. This puts it right next to the best power meters available.

ANT+/Bluetooth SMART

The G3 supports both ANT+ and Bluetooth SMART – which means you can use it with your favorite bicycle computer or smartphone.

1 Power Meter, 2 Bikes

Finally! With the POWERBEAT G3 2×2, you can add power to 2 bikes by simply moving the Comp Units from one bike to the next.



  • For one bike. You get 2 Sensors and 2 Comp Units so you can add power to both the left and right crank arms of your bike.


  • For two bikes. You get 4 Sensors (2 for each bike) and 2 Comp Units. The Comp Units can be transferred (takes about 15 seconds) between bikes.
