Patent ID: 7597337

Claim:
A method for stabilizing a two wheeled vehicle, at least during start of vehicle forward motion comprising the steps of: initiating rotation of a rotating mass mounted with respect to a steerable front wheel of the vehicle before the start of the forward motion of the vehicle so that the rotating mass is applying gyroscopic force to the front wheel at the start of the vehicle capable of inducing precession during steering of the wheel; initiating the forward motion of the vehicle using a mechanism that rotates a rear wheel of the vehicle; responding to crossed forces created by the precession induced in the front wheel by motion so as to reduce unintended tilting of the vehicle; wherein the step of initiating rotation comprises applying, and then withdrawing a rotation-inducing mechanism to the rotating mass, thereby creating the gyroscopic force that induces precession on the front wheel and that reduces the unintended tilting of the vehicle during steering of the vehicle.
