We would like to think that this is the definitive review paper on the linearized equations of motion for a bicycle.

R.S. Hand, ScM. Thesis, May 1988

This thesis on the stability of an uncontrolled bicycle is thorough and has the only relatively complete survey of papers on bicycle stability. The advisors were Jim Papadopoulos and Andy Ruina.

Here are other articles on bicycle mechanics, mostly by Jim Papadopoulos, mostly incomplete, highly redundant. Some have contributions from Scott Hand, John Olson, and Andy Ruina.

This is Jim Papadopoulos' summary of the bicycle dynamics equations and what he knew about them.
