I had a look at the bike in the local PUMA store. It is kind of cool, but it is quite heavy and the folability is poor. They take 750 Euro for it, which is not completely unreasonable, but if it would cost something like 500Euro they would even occasionally sell one... If you want to customize this thing, you will not have too much possibilities.
And on closer look the frame is a mess with its weld seams but it feels stiff and it rides well.
