Quarq TyreWiz

In the why-didn’t-we-think-of-that department this week comes the new Quarq TyreWiz, a real time tire pressure sensor that works on road and mountain bikes. Once installed, pressure is displayed on a smartphone app as well as certain GPS head units with ANT+ or Bluetooth Low Energy radio capabilities. You can even set high and low parameters so that an alarm will sound if you’re out of desired range. Price is $199 for a set.

Potential useful applications include getting precise readings when you don’t trust your floor pump or are using a pump with no gauge. You can also keep track of pressure while riding, when things such as temperature change, a burp, or a puncture that quickly gets sealed can all alter how much air is in your tire. With TyreWiz installed you’ll know if you need to stop and top off, or if you’re good to keep riding.

The TyreWiz looks easy to install. If your current set-up has a removable Presta valve, just unthread the existing valve core with an included tool, and then thread the TyreWiz sensor onto the valve stem. The sensor is powered by a standard CR1632 battery that’s claimed to last around 300 hours. It’s compatible with tube or tubeless tires, and even tires with anti-flat sealant.

Each TyreWiz sensor has an IPX7 dustproof and waterproof rating and weighs 10 grams per. Once activated, it updates tire pressure once per second. The Android and iOS app even provides personalized recommendations based on rider weight and tire dimensions.

    Neat device, but have they factored in the side effect of latex sealant in tires. A little bit of liquid spray is released every time the valve head is opened, and I’ve had to clean out my pump heads a few times from built-up latex clogging the line.

  • Fred says:

    I’m sorry but this is a fine example of technology gone way too far and too silly. ENOUGH ALREADY! We have to put air in our tires every time we ride anyways, so what’s the big deal to simply use an air gauge built into a floor pump, or buy a separate air gauge? For the price of $200 for a set of those you could buy one heck of nice floor pump with a very accurate gauge, plus not ever have to worry about replacing batteries just to use it darn thing, nor any worries about it failing! Then what do we do if it throws the wheel out of balance due to its weight? hmmm, no discussion on that, means some people may have to get 10 ounces of weight to put on the opposite side of the wheel from the TyreWiz.

  • Bnystrom says:

    Agreed, it’s just another example of technology for technology’s sake. It will probably die a rapid death in the marketplace, especially at $200/pair.

    BTW, I think you mean “grams”, not “ounces”.

  • David says:

    I think it’s a great idea. It would be very helpful to me for a variety of reasons. My only concern is the price. $199 is way to expensive. I’d purchase a set today if they cost half that. Hopefully we’ll see more affordable options in the future.

    Just wait until someone unthreads them from your valve stems leaving you without your $200 thingys, flat tires AND no way to air them back!
