This is an interesting device for biking aficionados that like their iPhones. You can combine your passion with your iPhone with your passion for cycling and use both at the same time.

iBike has just launched the iBike Coach which transforms your iPhone into a fully functional, multi-tasking computer for your bike. It features a comprehensive coaching app, a water- and shock-resistant case that works with any model of iPhone and a universal mount that means you can attach it to any bike. The app itself tracks cycling speed, distance, time, and has a map that you can follow as you ride. Even better you can share your cycling conquests with your fellow cyclists via some social media software.

I'm not really a cycling fiend myself but it sounds like a pretty good deal and i'm sure you'll appreciate that water and shock resistant case if you take a fall. I'd be nervous to take my iPhone out cycling for that very reason. iPhones don't seem to do well in a fall.

It's quite astonishing what iPhones can do nowadays. There's a device or app for everything. Our lives are going to operate entirely around iPhones soon, if they don't already. Coming up with a new innovative iPhone device or app is definitely the key to making your first million....
