Currently Google Transit is only available in the following cities:

We’re hoping that more cities will be available soon. And not just cities in developed countries.

We’re also hoping that someone comes up with a similar service but for cyclists. That is, if you plug in your coordinates and destination you could get the most bike friendly route for getting there.
