I've got an old giant escape which I lock outside. I can see it out my window and I've had to shout down at young teenagers I just happened to spot going past one night who saw it and came back pulling at it. My apartment is on the third floor and has a very tight carry up so I leave it there when I'm working in NY and use it to go to Grove St. I've had the seat and post stolen so now need to remove that. It's lasted the passed two years, depending on how busy the street is I think, putting them off a little. Having moved here from London I can say jersey city is more secure than there, it's crazy bad but then biking to work is definitely a bigger thing there are so much more bikes around. A good lock and be sure to secure the back wheel if not even both and cross your fingers
