Bikers (the pedaling kind, not the leather-clad, Harley-riding kind) can now use their iPhone or iPod touch to keep track of their workout, thanks to a new attachable computer from iBike Sports.
The combination of the Dash Cycling Computer and the company’s free iBike app turns the portable Apple device into a personal cycling trainer that tracks—among other things—speed, time, and heart rate.
The device uses ANT+ wireless speed sensors to track your pedal power. These sensors provide an accurate measure of speed, heart rate with varying target zones, and cadence (that's biker speed for rpm). It can also use GPS to track your route and can automatically store your workout data on a daily calendar.
And if you're the kind of not-so-easy rider who drops his or her iPhone or iPod on just about every block, the attachment comes with a tough, water-resistant case that allows you to use the touchscreen even while wearing your favorite pair of biker gloves.
The basic version costs $199 and the advanced version—which measures cadence, heart rate, and calories—costs $329. Both models are available for sale at Apple's online store or iBike's Website, and require either an iPhone 3G, 3GS, or 4 or a first-, second-, or third-generation iPod touch. The iBike app is available for download for free at the App store.
