If you ride in the center lane, the chances of getting nabbed off your bike are slim. That being said, if a cop does trail you, there are ways to lose them. But, in the end, it's not worth it. So if you see cops at the street corner. Just stop at the light.
FWIW, I take Grand st all the way East now. Avoids the cluster**** on Delancey and you get to play frogger with all the people in Chinatown.
