In the 3 years I spent living in Sweden, I came across quite a few different types of "vehicles" used in order to go from 1 place to another or to transport items. We say that the Swedes are very innovative. It's true. Their approach is also very practical and it seems they look for simplicity in their design.
Unfortunately I failed to take a photo of the many examples I came across (including the postman special yellow large bike). But here are a few examples anyway.
