Yes, I've folded and unfolded the bike lots of times now - it gets unfolded when I'm working on it, and then folded away when I'm not. The chainline seems fine so far. I haven't fitted the chain yet, but the inner chainring is right hard against the rear triangle (which is where it needs to be) so I don't see any problems there. The only difference really is that the chainguard presses rather more firmly against the stay for the front mudguard than it does on the standard set up, so if you try to spin the pedals when the bike's folded there's much more resistance. Hardly a deal breaker though.
