I was at a local bike shop yesterday checking out the Vitesse and couldn't figure out how to fold it down. The staff there didn't know either. The handlebars folded in between the wheels and the magnets wouldn't touch. From what I can tell from Dahon's website, it looks like that the correct way.
On my Mu SL, the handlebars fold outside the wheels and the magnets stick without a problem.
Would someone confirm this?
