Have you wondered why bicycle wheels come in different sizes? Why some models of mountain bikes have a choice of 26 inch diameter or 29 inch diameter rims? Do you know your rotational energy from your gyroscopic stability?  The bike is a fascinating, ongoing physics experiment. In its simple terms, to move forwards you’re only adding the physical capabilities of the body to the relative simplicity of the mechanical advantage gained whilst pedalling.  From this template, it’s been relatively simple for boffins to experiment, research and develop those terms learned in science lessons. They’re investigating acceleration, air and wind resistance, inertia, aerodynamics and friction.  But then lower-cost testing by passionate enthusiasts out of a Californian garage and an accident of…
