Don't be frightened by the lack of brand-name specs, these are pretty robust machines and I see no reason to suppose that Dutchie won't stand behind their guarantee. I've seen a fair few of these bikes around London, they have a sort of anti-cool cool factor, if you know what I mean.

Not my style, but if you want a traditional Dutch bike for practical city transport, I doubt if you'll find anything better for the money. As others have pointed out, lightweight is not an apt description; but if a bike like this is to your taste, my guess is you aren't planning on racing it.
