I've always been fascinated by the 2WD Rokon Trailbreaker - I've seen it advertised in those little B ads in the back pages of outdoors magazines for decades. Its got charmingly oddball looks and can go virtually anywhere you point it.
I can't quite believe how fabulous this is - the sound you hear is my mind blowing. The Valmobile, a Japanese collapsible motorcycle from 1961. The entire thing folds into a hard case no bigger than a suitcase. Posted by sushifactory, via Flickr
