the bicycle myth testing methods.

there were long overwrought threads on this topic on the old board, and while some people would never give up their pet theories, most of us agreed in the end that a bicycle operates by following ALL of the rules of physics, not just one or two. however, it occurred to me yesterday that it might be fun to devise a series of tests engineered to isolate all of the major forces at play, to view what happens when you eliminate or restrict to only one force at a time. the first test I came up with is a test to demonstrate the prevalence of countersteer; consisting of sensors applied to the headtube and wheel of a bicycle. a test subject rides the bicycle through a basic obstacle course; and the data on distance and steering motion is loaded into a robot simulator, which travels the same route, but with the steering angle exaggerated. a wide front wheel, and a narrow back wheel loaded with paint would provide a track which could be viewed to show which direction the front wheel turned at every point on the track.
