I moved into the West Village last month. I lived in Manhattan for the first 26 years of my life. Average speed was slow because of traffic. Now that I can ride the Greenway, I'm astonished at how much ground I can cover in just a few minutes. It's practically like the number 2/3 train.
Coming late to this game. You can add me too. I live in Manhattan, Lower East Side (and got here before it was hip, hence I can afford the rent). I ride a Brompton, and now that it's winter, bike share, since bikes are actually available, and I can let their bikes get salty.
