I am considering the Swift and the Dahon Cadenza. Haven't ridden either bike. The Xootr shop had no Swifts on hand, and I didn't see a Cadenza there or at other Dahon dealers I've visited.

If only Xootr offered a Shimano Alfine hub on a stock model, with the Shimano roller brake, priced competitively vs the Dahon Cadenza, I would go for it.

The internal hub would be more robust when the bike is being transported, and the roller brake would offer better stopping in rain. It could overheat going down a long hill, though, so perhaps a better apples-to-apples scenario would be if the Xootr Swift had disk brakes like the Cadenza.
