It's getting cold outside, so if you're a cyclist and worried about tracking your workout while indoors, technology is coming to the rescue. XSPIN from PAFERS claims to be "The World’s First Cycling 'Appcessory' for Indoor Fitness Equipment."
The XSPIN uses Bluetooth to detect motion and pedal speed in real-time on stationary bicycling machines, as well as elliptical and bikes with a trainer stand. The data is transmitted to their apps, Cycle on Earth and Cycle Rush. Cycle on Earth works with Google Maps to ride a real world route. Cycle Rush offers a more traditional gym-like workout, with music and coaching.
The portable XSPIN has a battery that lasts 600 hours, which is a lot longer than I'd last on a fitness bike! In fact, I have a sample of the XSPIN to review but I've asked a serious bicyclist/iPhone programming friend of mine to give it the once over. I will update this post with his analysis soon. In the meantime, you can look for this bluetooth-enabled cycling training sensor at Amazon or Apple Stores.
