Right now, I'm in Anchorage. I'm going to be moving to New Orleans soon for college.
Anchorage is cold and hilly; NO is flat and humid.

When I needed a utility bike here, in 2008, I bought an Xtracycle and mounted it on the back of a heavy steel MTB frame. I needed the wide range of gears, so I swapped out the innermost front ring for an even smaller ring for hill climbing. The use of the standard 26" tires allowed me to use Nokian studded tires. The bike runs great! It's also very heavy and big. I have to carry it up stairs and I doubt it would fit in an elevator. Also, I can't put it on a bus bike rack. It's just too long.

Pro:
Standard tires - use standard ice studs (but in Louisiana, I doubt i'm going to need Nokians!)
Carry lots of stuff
Rides well as my main bike
Wide gear ratio for hills (which I think are not such an issue in New Orleans as they are here in the mountains)

Con:
Can't load on public transit
Odd length
Heavy, will be a bit spendy to ship crosscountry

So i'm contemplating selling my old trusty steed before I move, and getting a new cargo bike when I get there! Specifically, I was contemplating a Worksman LGB/LGG. A bit warily, as i've never actually seen one, nor do I know if it would work well for regular commuting and generally riding everywhere and every day. in fact, if I need a bus trip, I have a conversion recumbent which can be a bit of a pain and is also heavy.
The hope would be that it would be easier to load on a bus or into things like bike lockers. I don't have the experience with the bike in question to know how well it works for everyday use.
I'm open to other ideas if anyone knows of something even better, too.
