The combination of the Dash Cycling Computer and iBike’s free iBike app turns this portable 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.
