Not quite in the wild - here is a very early folding bike from the WW2 which I saw on my visit today to the Coventry Transport Museum. Well worth visiting if you are in Coventry (England). This museum tells how the local engineering firms first developed sewing machines, then bikes, then motobikes and of course cars and other vehicles. The bike story is huge and so I would highly recommend a visit for all bike fans!
Outside the main building in the centre of Coventry.
WW2 folding bike - could be used with a parachute. Thanks @
