United Kiltrunners e.V. is a charitable organization founded in Fürth in 2015. I can find no Scottish connection for the kilts. Possibly when they run for charity their kilts make them more noticeable.
One of their current projects is providing rickshaw rides for senior citizens. This is called Radeln ohne Alter – cycling whatever your age, although it is more like being transported. There are definitely some nice green areas around the confluence of the Rednitz and the Pegnitz. The Kiltrunners have eight e-rickshaws, which I suppose are electrically assisted.
