On the web site of Rohloff you can see a unique heavy duty tandem bicycle.
This article is online already for some time, but it is hidden on the German pages and it may have not attracted your attention by now.
The story is available in German language but - as pictures say more than 1000 words - you can imagine the force this Speedhub is subjected to.
And this vehicle definitely comes with a Fat Tyre Speedhub wheel even before the 170mm Rohloff Speedhub XL was available.
This way to the story.
