Here is a wireless device that will track much of your ride data includence cadence & heartrate, calculate calorie burn and plot your route via GPS. Just wear it on you wrist for any bike you ride. Oh, and it is also an MP3 player! No, really!!!

I am doing some testing of the device for Motorola and it is reviewed on my blog.
