Long Island Bike Shop is the place to go. It's owned by BMX riders, and everyone who works there is a rider with tons of knowledge. They carry all of the high end brands like S&M, FIT, Odyssey, Profile, etc. I also saw some really nice mid range complete bikes the last time I was there. I've been buying my BMX parts there for years now. I don't live in NY anymore, but I try to stop there when I visit.
They're located on Merrick RD. off of RT. 112 in Suffolk County. It's a hike, but I felt it was worth the trip when I lived in Brooklyn.
