Now that winter has hit the country, cycling has moved indoors for much of the U.S. That means straddling a stationary bike or throwing your trusty road or mountain bike up on a stand (or if you’re really brave, rollers).
That’s where the Xspin comes in. it’s a small box filled with sensors and a low-energy Bluetooth 4.0 radio that attaches to a crank arm and sends speed, distance and cadence data to an accompanying app — either one of two developed by its parent company, Pafers, or a handful of popular third-party cycling apps, like Strava or MapMyRide. It’ll also work with ellipticals (though it obviously attaches differently, since ellipticals don’t have cranks).
