Cars with TPMS sensors are pretty common these days. These are the ones that tell you when you’re getting a flat tire, by constantly monitoring the pressure within. It’s smart, and safe, and about time cyclists got the same treatment. The BTPS sensor aims to do just that, connecting to your smartphone and informing you of the pressure of your tires accurately, between 0 and 174psi. Admittedly, the device is more useful as a convenient indicator of tire pressure; it sure beats having to bend down every time. And since many road bikes need a regular air adjustment, the simple phone-glance convenience is appreciated.
“The BTPS unit itself consists of a pressure sensor, circuit board, and battery. When used with tubeless tires, it is mounted on the rim tape. If tubes are being used, it’s stuck right onto the tube, like a patch.” Currently weighing only seven grams (0.25 oz), it shouldn’t affect your ride in the least. It’s going through funding with Kickstarter though, and is quite far from its goal. Still, if you want one for yourself, a $140 pledge will get you a pair of tubeless-specific BTPS units.
