Hiya folks,
I've a collection of novelty cycles for occasional use with my circus skills workshops.
They include mini penny-farthings, backwards pedalling cycles, eccentric wheel cycles, reverse-steer cycles and a gyrobike. Also one where the saddle is connected to cranks on the back wheel. Motion is achieved by pushing down with one's posterior and repeating the action!
If any schools are interested in seeing them please let me know. It could be an interesting project for schools to make some of these. Not only could pupils make them, they could ride the finished product - a lesson they'd
