I found a very cool and bizarre-looking bike in Berlin (in Germany) and was very confused about what it in fact "is"; Has anyone got an idea? — To me, it almost looks like some sort of cannibalized bike/moped/mini-motorbike hybrid:
The owner was an older guy who told me that it's "custom" but he had bought it the way it is except for the front case and Winnie-the-Pooh squeaker, which he'd added himself.
