Bugger! You beat me to it with more information as well. From The Vintagent:
"More fantasies! This cyclecar was built by Tim Gunn of the Old Bicycle Showroom in London, using mostly bicycle components, with a J.A.P. sidevalve engine. The steering arms are made from bike pedal crank arms, the axles are bike cranks, the steering hubs are bicycle headstocks, etc. All very simple, clever, and it works! A good look at cyclecars makes me wonder why more people don't build them just for fun...dangerous fun its true, but hey, we're bikers!"
