Bikely

Put very simply, Bikely helps cyclists share knowledge of good bicycle routes. It can be quite tricky traversing a car dominated city […], particularly when you need to travel an unknown route to a new destination. But the chances are, someone has cycled that way before you. Bikely makes it easy for him or her to show you the best way.

Bikely is very young right now. What it needs more than anything is people like you to submit your favorite bike paths. As we collect more and more routes, Bikely can become an incredibly useful resource for the cycling community!
