I don't own a shop in NY, I rep in NJ. Actually, I'm not a good source for NYC shop info, but if you'd like to cross the river... what kind of a shop are you looking for?
If you want a super-high end road shop with Orbea, Pinarello, Colnago as the primary brands that's Strictly Bikes in Ft. Lee.
If you're looking for the kind of shop that has NOS GT Karakoram from 1996 (with or without a Q21R) there's Original Bikes in Saddle Brook.
