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.



The manufacturer no longer makes this product and therefore, it is being sold without a warranty, nor do we accept returns on it under any circumstances. If either during or after the installation process, something doesn’t go as planned, the product doesn’t work as you thought it would, you break a part, etc., the best we can offer is to sell you a replacement part, if we have replacement parts in inventory. To compensate for the lack of warranty and returns and the additional risk associated in buying this product, we have it marked 30% off. Please only purchase this item if you are okay taking on this additional risk and responsibility. We are happy to answer any questions you might have and are here 7 days a week to support all of our customers. Thank you!

    I received the WATTEAM POWERBEAT G3 and am very happy with this product. It is very easy to install, easy to calibrate. Paired up with my Garmin 520 on the first attempt and haven’t had any issues with it. Power Meter City shipped fast(delivery to russia 14 days).This is the first WATTEAM POWERBEAT G3 in Russia.

      Hi and thanks for the review on your new POWERBEAT G3 power meter. They are a nice upgrade over the G2 and we’re excited to be using them ourselves!

  2. Rated 5 out of 5


    Completed the installation yesterday. All in All not very hard. But in european weather conditions (indoor temparatures and winter als well) you have to wait min. 3 days for the glue to dry, to be on the save side. The rest of the procedure has little interuptions in it. The comp unites take two trys to connect with the app. My waterbags have 4,4 kilos, even when they are full. So i will make a second calibration with exakt weights. All in All i belive in this product, powermeters dont need to be as expensive as they were in the past. Im very exited to try the PM in action.

      Hi Christof. Glad things worked out for you and we agree, always best to give the glue plenty of time to dry. We hope you enjoy them!
