Concept Bikes & Bike Innovation - for better or worse

stuff like [unlikely collection] Should be allowed

The problem the UCI has is in regulatory draughting. They made enough of a balls up when they just drew a bike of conventional 11-tube shape and added some random dimensional limits. Constructing a sensible definition of an acceptable bicycle without first drawing a bicycle is surprisingly tricky. You have to start with a human being, and limit the position he can adopt, then define how he may touch the bicycle, and finally create a mathematical envelope to contain all the parts of the bicycle which hold those contact points together. When you think you've got that about right (i.e. it works for all morphologies, and all cycling disciplines, and it doesn't have any loop holes), you get to the hard bit; designing a way of enforcing the regulations in a way which is consistent with the needs of race organisation, international trade agreements etc.
