About the WATTEAM POWERBEAT Single Power Meter

Meet the latest addition to the POWERBEAT family, the WATTEAM POWERBEAT Single Power Meter. Like the original POWERBEAT, the Single is a user-installed power meter that attaches to the crank arm in a simple, 30-minute procedure. However the POWERBEAT Single only attaches to your left crank arm. It takes your left side power and doubles it in order to calculate total power (which is how all, left side power meters work).

Once installed and calibrated, the POWERBEAT provides both power and cadence data and is accurate to within +/- 1.5%. The POWERBEAT is extremely lightweight at only 18.9 grams, features a rechargeable battery with 60-hour life and offers both ANT+ as well as Bluetooth SMART compatibility. Perhaps best yet, at $259 the WATTEAM POWERBEAT Single Power Meter is the most affordable power meter you can buy.

    Got this one from PM City a few days ago and have already put in 100 miles into it. The install was super easy and the calibration seems to be true. The only reason I don’t give it a full five stars is because they ran out of silicone bands to support the cable and what the kit included were these super cheap stickers. Watteam did say that they will be shipping replacement bands out but I don’t have an ETA on when that will happen Also, the cable itself makes me a bit worried since it feels a bit flimsy. Only time will tell how it holds up. Thus far though it has been working as advertised.

      Thanks for the review. You know power meters have come a long way when you can get a quality, direct force power meter for this price! Glad you like it. We will let you know when the silicone bands are back in stock. Thanks!

    Brilliant power meter that works as advertised and really is simple to setup. For international buyers like myself Power Meter City is fantastic to deal with and I would not got else where when I order the right side upgrade kit once they are available.

      Hi Modarm. Thanks for leaving a review on your POWERBEAT Single. It’s tough to beat $259 for a direct force power meter 🙂 Glad you like it!

    I bought this power meter from Power Meter City with some apprehension. There are a ton of good and mediocre reviews of this unit but I figured why not. I went ahead and got it but initially had some problems. I ended up reaching out to WATTEAM and they quickly sent me a new comp unit as my initial one was defective. Since then, it’s been very accurate and working well. The only thing I would suggest for anyone looking to purchase this is to ensure that your water bags are exactly 4.5kg, or your power readings will be off. I was lazy when I was filling up the bags and my power readings were really high. After re-calibrating with the proper amount of water, things are back on track. Thanks Power Meter City!

      Hi and thanks for the comments on your POWERBEAT Single. Yes, it’s pretty important to hit the 4.5kg mark as closely as possible as the zero-offset is set off that exact weight. I’m glad to hear you’re liking the data now. Let us know if there is anything else we can do!
