Stable right hand steady turns with right hand applied steer torque

by Dale Lukas Peterson — last modified Apr 20, 2011 01:05 PM

According to the nonlinear equations of motion of the benchmark bicycle model that I have derived, stable steady turns to the right do not always require a left handed steer torque. read more...

Very cool papers proving gyro and caster aren't required for bicycle stability are out.
