The Central Park stuff off of the pavement is very illegal, like confiscate your bike illegal.
I live in Weehawken also, Park Ave; the other gypsy bus line.
Here is a local tip i only just found out: Check out Shortys at 576 9th Ave, on the back side of the Port Authority for great Cheesesteaks and Sausage and Peppers and surprisingly good selection of beer. I had always been looking for a spot to hit for either a quick bite before meeting friends, or quick bite before getting back on the bus. I have been here for years and only just found that place out.
As said before there are no good bike shops in the area as far as mechanics go. James Vincent Bikes in Union City has a lot of parts though. The bike shop in Hoboken is tiny and pretty much useless. I can't believe a yuppy mecca like Hoboken only has one small bike shop.
