New Watteam Powerbeat Single power meter costs just $259

New single- and dual-sided power meters might just be the most affordable we've yet seen

As you know if you read road.cc regularly, there are more power meter options than ever before, and with the growing choice comes more accessible prices. But by far the cheapest we’ve yet come across is the new Watteam Powerbeat Single. It’s priced at just $259 - it's going to be available in the UK but we're just waiting on the UK prices, we'll update as soon as we get them.

There’s also a Dual version, providing left and right leg power and balance data, for $399. And if you have two bikes, they’re offering two Dual power meters for $699. Even if the sterling price is close to the dollar price, those are appealing prices compared to the current options in the increasingly crowded power meter market.

We first reported on the Watteam Powerbeat back in 2014. The US company has developed a power meter that simply clips onto the pedal axle, and can be used with any crankset. It reckons self-installation is a hassle-free task, but if you don’t want to fit it yourself, the alternative is to send your crank to Watteam and for $99 (with free shipping) they’ll install it for you.

As well as the supposedly simple installation and compatibility with any aluminium crankset, it’s very light, a claimed 24g per pod. As with most power meters, it’s using ANT+ and Bluetooth to relay the data to a suitable app or training program. The rechargeable battery is claimed to be good for 60 hours of use.

The Powerbeat Single is a single power meter, like Stages, that measures power from the left leg only. It can be upgraded to a dual-sided power meter at a later date if you need more data. It doesn't look quite as compact as the Stages solution, and we're sure some of you will have concerns about the durability of the pod being exposed above the crankarm.

The Powerbeat Dual is the company’s flagship power meter. With a pod on each crankarm it can independently measure left and right leg power, provide balance data and torque efficiency.

“Watteam PowerBeat uses the most advanced strain gauge technology, along with an optimized processor, accelerators and gyros to accurately detect your power output,” says Watteam.

“Built from rods and springs, our worldwide patented sensor attaches easily to both of your crank arms. It senses your pedal stroke up to the millisecond, recording the direct and immediate torque that you apply.

“Our sensor then feeds the data to our patented algorithm, located inside the comp unit, where it is translated into accurate power data.

“The Comp Unit, once attached to each of your pedals, transmits the data to your smartphone via ANT+ or low power Bluetooth or to your cycling computer, enabling live tracking of your energy output.”

Obviously, the Powerbeat has piqued our interest, and we’re hoping to get one in for a test soon so we can see if it works and how consistent and accurate it is compared to other power meters currently available. They will be available in the UK but we're just waiting for details on availability and pricing, we'll update this article as soon as we find out. More at https://watteam.com/

Has the Avio powersense been released yet? it was mentioned on here in spring but the company website has always said out of stock.

I'm glad the article mentioned durability as something to be concerned with. I'm not sure these will last if traveling with them in and out of bike cases. I think 4iiii or Stages will be my next power meter.

The durability of the transmitters should be fine as they're solidly built and firmly held in place by the pedal.

The strain gauges would be a concern with them being glued on but more importantly the frequent plugging/unplugging when charging and transporting could put a strain on the cable and tug at the strain gauge. The pictures show the cables being retained by substantial plastic strips but they've now changed these to flimsy adhesive stickers that do stretch with use.

Have you got an image of a crankset with them fitted? it's difficult to spot them in the photos.

Looks a bit vunerable to me sticking out like that.

I've had a pair of the Powerbeats for a couple of months.

I'm pretty competent with engineering and I followed the fitting instructions to the letter and allowed 48 hours cure time yet within six weeks the left strain gauge began to detach itself and then last week, after only eight weeks, the right strain gauge began detaching itself.

The adhesive still had a good bond to the crank but detached from the strain gauges despite the adhesive originally being applied to them. Had the adhesive failed on one strain gauge I could have put it down to my error but for it to fail on both within a couple of weeks and both within two months of fitting suggests something else.

Fortunately my brother works with strain gauges on a daily basis so I've sourced what I hope is a better adhesive so I can continue using them but time will tell.

Also, the claims of battery run time can be misleading. Sure, each charge might last the stated battery run time but the available time in use when riding between charges has proved much less.

Despite the low price I couldn't recommend these if you're looking for a fit-and-forget power solution. Mine have now done 1,000 miles but as mentioned above it has required more maintenance to keep them going than I anticipated.

I am no expert but it seems to me that there is no cheap option if you want durable power measuring devices.

stages aren't bad if you buy the lower level groupset ones (105 or rival)
