One of the reasons I was interested in the mini Velo was my old Bianchi made folder while fitting fantastic doesn't close very tight and so it moves around while riding. Its not a big concern, but having a nice tight fairly cheap bike that fits and has plenty of options for making the bike fit was really great. I still like the Bianchi which happens to have a coaster brake and fun integrated rack, but if the Windsor fits easily in the trunk the Bianchi might find itself on Craigslist. I have a Dahon Boardwalk 6 which I bought for my wife as well if I need a really great bike that also folds for commuting purposes.

no1mad, If you are seriously thinking of a mini velo for your next commuter I would say its worth considering with your multimodal commute. The BD mini velos should be cheap enough to let you try one out without the worry you blew all your cash on something you don't really like.
