About the WATTEAM POWERBEAT G3 Single Power Meter

If you’re looking to add power to your road or CX bike on a budget, the all new WATTEAM POWERBEAT G3 Single Power Meter is the perfect solution. Just like POWERBEAT Dual, the POWERBEAT G3 Single attaches to the crank arm in a simple, 30-minute procedure. Once installed and calibrated, the POWERBEAT provides power data that is accurate to within +/- 1.5% – the industry standard.

Whereas the Dual attaches to both crank arms, the Single attaches to the left crank arm only. Like all left side power meters, the POWERBEAT G3 Single takes power from your left leg and doubles it, in order to compute your total power. With this single-sided solution, you get a ton of power meter for the money. In fact, at $259, the G3 Single is the most affordable direct force power meter on the market today.

The WATTEAM Single is also extremely lightweight at only 35 grams of added weight, features a rechargeable battery with 60-hour life and is compatible with both ANT+ and Bluetooth SMART devices. Did we mention it’s also upgradable? You can purchase a right side upgrade kit at any time and turn your G3 Single into a dual-sided power meter.
