Introducing the long awaited WATTEAM POWERBEAT Power Meter! Redefining what a power meter is capable of, the POWERBEAT is the first user-installed power meter with features, functionality and accuracy once found only in factory installed units.

The POWERBEAT attaches to the left and right crank arms in a simple, 45-minute procedure requiring only basic technical skills. Once installed and calibrated, the POWERBEAT provides power data that is accurate to within +/- 1.5%. In addition, it provides true left/right power measurement.

The WATTEAM POWERBEAT Power Meter is extremely lightweight at only 18.9 grams per side, features a rechargeable battery with 60-hour life and offers both ANT+ as well as Bluetooth SMART compatibility. This means it can be used with a bicycle computer, smart phone or tablet.



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. In addition, at some point in the future we expect that WATTEAM will shut down the app. When they do, it will make performing installations, calibrations and other changes to your power meter impossible. To compensate for the lack of warranty and returns and the additional risk associated in buying this product, we have it marked 50% 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’ve been using Powerbeat for around 2 months now. Initially, the installation was easy and I had zero problems while riding over 1,000 km through cold, moderate, dry, rainy, and snowy days. This is the only power meter I have so I can’t make a comparison. As everyone knows a power meter makes a huge difference in training/improving. But when it comes to buying one, I feel like Powerbeat is underrated. The price is simply incomparably cheaper to other well-known brands, and it provides essentially the same data. Overall I am very satisfied.

      Hi Ironfoot. Awesome review! Glad you are enjoying your POWERBEAT. A few of us here are also training with it at the moment with similar results. It’s a great PM!

    Certainly the best value proposition, especially if you need/want dual sided. The only hard part about the installation was finding the time to let the glue cure. I needed to let it go 48 hours in a 68 degree room. So, the system sat on my desk until I had to travel for 2 days.

    As a non racer, I don’t really need this, but I do have some fast friends I’d like to be able to keep up with. I’m recovering from a left knee replacement, and wanted dual sided to track my progress. Not surprisingly, my left leg tends to come along for the ride. My numbers on a left only meter would be low enough to be frustrating. It’s nice to see the progress, and balance, pedaling efficiency and smoothness are improving. Although when my competitive streak takes over, it all goes out the window trying to beat my previous peak and NP. Although I have nothing to compare with as with Ironfoot this is also my first power meter. Despite comments about short high power not registering, I have had two second power readings over 1100W a couple of times. If only I weighed as little as Quintana that might make me a decent sprinter.

    Overall, I am very happy with this meter. I just need to remember not to display power while riding once in a while and just enjoy being on the bike. It’s hard not to stare at the power reading sometimes.

      Hi Robert. Thank you for the great review. Sounds like you have a pretty good handle on things… nice job. It will be fun for you to be able to monitor the improvement of your left leg. Please let us know if there is anything else we can do. Thank you!

    I’ve been using the Powerbeat Dual for a month now with my indoor trainer. So far it is working fine and without any issues as I have it linked to my Garmin and Zwift. The only problem I had was with the gluing and installation of the sensors. I live in the UK and it has been very cold around here, so I assume the sensors didn’t dry properly and came undone (but also I think I failed to cover with glue the whole surface of the sensor properly). I contacted support, they sent me a new free pair straightaway by FedEx. I was recommended to warm up the glue this time with its plastic pack included in a warm glass of water for 10 seconds, just before starting the process. I believe that did the job. I also waited a bit longer than 48 hours this time before touching the bike. If you don’t mind the DIY aspect of the installation, I recommend this product.

      Hi Luis. Thank you for your review. I’m glad you’re up and running with the POWERBEAT. Yes, the installation process takes some care and it’s always better to wait 36-48 hours for everything to set. We hope you enjoy using it both indoors and out, and are here if you need anything else!

    I was a little apprehensive of these at first but decided at the price point this was going to be my best bet. The installation is straight forward and the app had all the necessary videos to help with the installation. The most difficult part for me was the sanding to remove the finish from the crank arms. Took some time to do because the finish was pretty thick on mine. Watteam has done a very impressive job with their instructions and making it possible for just about anyone to install.

    I’ve been using the unit now for over a month both on a trainer and outdoors with great results. Linking was easy with Garmin, Zwift and what I use to train Xert. So for me this was a great purchase and the service I got from Power Meter City was great.

      Hi and thanks for the review. Yes, WATTEAM has done a pretty amazing job of creating a power meter that can be installed pretty easily as long as you follow the instructions. I’m glad you are enjoying yours and thank you for letting us help you out!

    I bought my power meter from Power Meter City in January. I received my order very quickly. I installed the sensors per the instructions and everything was fine for about 1-2 weeks. After that time my left sensor would not read and my power was cut in half and my balance was 100% right side. The next ride was in the rain and while I was washing my bike afterwards, the left sensor pooped off as I was drying the crank. I contacted support and they sent me a new sensor install kit free of charge. I installed that sensor per the new and improved instructions and on my first ride I noticed that my power was still unbalanced. So I contacted support again and they gave me a free professional install. I had to send my crank in but they paid for all the shipping costs and had my crank back to me in less than a week. The power meter now works perfectly. While I had some issues, customer service is top notch. Now that my Powerbeat Dual works perfectly I will give it 4 stars. Overall happy customer.

      Hi and thank you for the product review. Since this is a user installed power meter, sometimes there are indeed support issues with the installation process. However, both Power Meter City and WATTEAM are here to offer you any support that you need. I am glad you are up and running and are enjoying your WATTEAM POWERBEAT Power Meter!

    Bought the Watteam Powerbeat Power Meter in April. I am really impressed with the unit once I got it working. The only problem I see with the entire process of installing the unit is the epoxy resin, you need to move fast, and you need to apply enough epoxy. The first install I did, I did not get enough epoxy on one unit and it fell off after 2 days. (contacted Watteam and they sent out a replacement sensor and all the fixings to install the new unit). Since the new install I am very pleased with the unit and how well they work. (I am using a Garmin forerunner 935 and am having no issues with dropouts). Not that this makes a big difference, but I have been building engines, bicycles, wheels, etc. for decades so using epoxy is no big deal for me, but this epoxy is a bit challenging. The one things I would recommend is buying the protection covers, during a recent ride I threw a chain and if I had continued to pedal I am sure I would have ripped the unit from the crank arm. Bottom line would I buy this product again, YES! Very pleased with how the buying process went with Power Meter City.

    I had the dual sided Powerbeat factory installed on a new Shimano 105 crankset. I decided to go with the factory install for 2 reasons. First of all when I purchased the power meter the factory install was being offered at no charge. Second I would rather have someone that has done this before install the sensors. BTW It took them 2 weeks not the 2 days that is advertised to do the install so if you go with the factory install be patient it is well worth the wait. Thanks to Josh at Power Meter City for keeping me informed of the delays at Watteam during the installation.

    Once I received the power meter I had some difficulty using the Powerbeat phone app and connecting to may Garmin. I have several power meters including a Powertap G3 Hub, Garmin Vector 2 pedals and a Quarq D Zero crankset. Comparing the Powerbeat Dual to the Garmin Vector for dual sided power metrics I cannot see any difference. The only thing missing is the Garmin Cycle Dynamics. If you can live without that, the Powerbeat will perform just as good as the Garmin Vectors and at a lower price point. The Powerbeat is a very good choice for dual sided power.

    One thing I really like about the Powerbeat when compared to my other power meters is the ability to use any wheels or pedals on my bike. So far I am very happy the Powerbeat power meter.

    I bought a Watteam Powerbeat in early May. It’s now early August and I’m still having issues.
    Gluing isn’t bad, you do need a hot room though (over 80f for 24 hours). Once installed, set up, and calibrated correctly, this seems to “work” in that it does occasionally send data to the head unit that may or may not be accurate.

    1. The PowerBeat is (at least with my wearable Garmin) VERY sensitive to head-unit placement. Don’t bother with wearing it on your wrist. Behind the stem worked for me.
    2. The calibration bags must weigh 4.5kg EXACTLY each. I bought a fishing scale for $7 from Amazon; that helps.
    3. If you can, put hooks in rafters for the calibration – it’s a LOT easier than balancing your bike upside-down with a 10lb weight on a pedal.

    Issues I’ve had:
    1. First sensor went on okay, but returned bad data. Contacted Watteam support; they said it didn’t bond well. Sent new sensor. Scraped off old sensor; put on new one.
    2. Second sensor went on okay (“we sent you the good glue this time”) but I was getting big drop-outs in my head unit. Contacted support. They sent a new comp unit.
    3. Installed new comp unit. Experimented with head-unit placement until I found somewhere that gave me data without dropouts.
    4. Wouldn’t turn on before a big ride (and yes it was charged). Came home, charged again, and it worked fine. Didn’t inspire confidence.
    5. This morning it gave readings that blew up my ego but I don’t think are right. My FTP jumped about 12 watts from December to March; it didn’t jump 120 watts from March to August.

    Support is spotty – sometimes they get back to you in a few minutes; sometimes it’s days.

    Bottom line: Had this unit all summer. I’ve spent a good chunk of the time I’ve owned this unit waiting: for support to respond, on a new part, for glue to dry. The most important feature of a power meter is that it provides consistent and reliable data, that it “just works”. This one doesn’t. And I’m past the 60 day return period and don’t have stacks of cash to get a different one, so I’m stuck wrestling with this one.
