without gyroscopic or caster effects,

Linearized dynamics equations for the balance and steer of a bicycle: a benchmark and review - including appendix
J.P. Meijaard, J.M. Papadopoulos, A. Ruina, and A.L. Schwab. Proc. Roy. Soc. A., Volume 463, Number 2084 / August 08, 2007, pages 1955-1982. DOI 10.1098/rspa.2007.1857.
We would like to think that this is the definitive review paper on the linearized equations of motion for a bicycle.
Comparisons and stability analysis of linearized equations of motion for a basic bicycle model
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.
Second order kinematic constraint between two bodies rolling, twisting and slipping against each other while maintaining point contact
Suresh Goyal, Cornell technical report TR 89-1043, October 1989.
(A possibly related paper, Jim thinks, is "Les mouvements de roulement en dynamique"
Additional "Cornell" Articles
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.
