Though titled, “MotoGP Basics Tyre & Front Suspension” this video is a very good dynamic explanation of both the vertical (gravity) and lateral (radial or centripetal) forces acting against tyres and wheels. These same forces (albeit much less in N)
which are acting upon a bicycle as well.
When lateral force is greater than vertical force…(usually the front) wheel go buh bye… 😛 Referred to as a wash out or a low side. Your bicycle is a rolling physics lab, it is an amazing piece of machinery. Efficient and relatively simple, yet the complexity of applied forces in action are astounding.
Another part of the video explains the action of the front fork suspension on a motorcycle, which is the exact same action as a mtb/cross bike fork. And btw… I know ‘Air’ is the hot ticket right now in mtb suspensions, but the best forks in the world (GP/SBK) are utilizing oil and springs, so that should tell you something…
