Step-through bike for Xtracycle build

[sgtiger]

DD has outgrown her trailer and I've been looking into options to tow her and her bike. Originally I was going to purchase a FollowMe, but I'm thinking I'd be better off putting the funds toward something I can use beyond the next couple of years. Right now I think that the Xtracycle offers more versatility for me than any of the other cargo bike choices out there.

I was thinking about getting the Radish but I'd like more clearance than the current model offers. The 2010 Radish is coming out and it's more of a step-through design but I'm disappointed that they decided to not put disc tabs on it and I'm not thrilled about the feel of it either (local LBS has a prototype). It has too much of a cruiser feel to it.

The LBS is recommending a Breezer Uptown8 with FreeRadical conversion kit and that would be fine if it was flat around here but I live in a somewhat hilly area and I'm the biggest hill wimp around.

So I've been looking around and I've found the the Jamis Commuter 4 in a step-through frame that seems like it would be a good candidate for a conversion, but I'm wondering if the Alfine rear hub would work for an Xtracycle? And is there any other step-through frames that might be good options? BTW it doesn't have to have an internal hub, but I would prefer disc tabs, not mandatory though, on the fork.

Any advice would be appreciated. Thanks!
