Flying Scotsmen - bicycle automata

Model of two bicycles from the Riverside Museum collection. One is the oldest surviving rear-driven bicycle in the world, built by Gavin Dalziel circa 1846. The other is a copy of Graeme Obree's Old Faithful, on which he broke the world hour record and became World Champion twice.
The mechanics are a simple pulley system. Many thanks to Keith Newstead for advice on making this. www.youtube.com...
