As a cycling Manhattanite I'm not surprised at Bloomberg's comments. He basically hates cyclists (at least since the Republican convention in NYC). BTW, bad weather is not much of an issue here. He's out of his mind!!!
There are some bike lanes in Manhattan but they usually have double parked cars, trucks and police cars in them. Also, there is no enforcement of the bike lanes which makes them kind of useless. And they are few and far between. There is no bike lane I can use to get up to Central Park (and out of the city) from my apt without riding in crazy traffic first. Fortunately, the new head of the NYCDOT is an avid cyclist herself (Janette Sadik-Kahn) and is looking into bike lanes separated from moving traffic. Probably won't happen in my lifetime though.
