This publicity release mis-advertises what is new here.
From the publicity release: Now, a new analysis says the commonly accepted explanations are at least partly wrong. The accepted view: Bicycles are stable because of the gyroscopic effect of the spinning front wheel or because the front wheel "trails" behind the steering axis, or both.
From a Wikipedia article (http://en.wikipedia.org/wiki/Bicycle_and_motorcycle_dynamics http://en.wikipedia.org/wiki/Bicycle_and_motorcycle_dynamics): In 1970, David E. H. Jones published an article in Physics Today showing that gyroscopic effects are not necessary to balance a bicycle.
In fact, Jones' article addresses the steering axis question, as well.
What appears to be new here is the mathematical analysis. From Jones: I have not yet formalized all these contributions into a mathematical theory of the bicycle...
