Want to Ride your Bike around Town, in New York that is, check Ride the City
I am not sure I would feel comfortable riding a bike around Manhattan what with potholes, crazy cabs and the rest.
Some parts of New York might make the cut though.
Want to sketch ways to get around town on 2 wheels in a relatively safe fashion some people stepped up to the plate.
The recently launched Ride the City helps you find the best bicycle route between 2 points. It might not be the shortest but it tries to offer the safest by locating routes that maximize the use of bike lanes and green ways.
