My longtail cargo bike has made car-free living in the city so much easier for me and my family, but I couldn`t imagine having one if I still lived in Queens (or anywhere in NYC). Looking back, there just wasn`t anyplace I could possibly store the thing. Bringing it inside might have been OK, in some places - if I was single, but no matter how useful my wife thinks the Mundo is, there is no way she`d ever let me keep it in our apartment. Here, most apartments have bicycle parking areas for residents so I keep the bike locked outside under a shelter(I cover it with a big motorcycle rain cover).
It would be interesting to know more about the demographics of longtail cargo bike owners. I`d imagine most longtail owners living in the city are single, and most longtail owners are people with families living in the suburbs.
