- Here is a diagram of a bike moving from left lean to right lean.
- Because the tire is not knife edged but round, in doing this it rolls
- from left to right. So, as can be seen, the centre of bike rotation
- with respect to the road is underneath the road. It's so easy to
- forget these little details isn't it?
