Abstract

For bicycles or motorcycles that are running straight, the following conditions should be satisfied. (1) Balancing stability should be retained. (2) Directional stability (route retention) should be retained. Why can a 2-wheeled vehicle run without capsizing? This has long been a problem stimulating people’s keen interest, and the cause was once said to be gyroscopic effect. However computation reveals instantly that the gyroscopic effect is almost negligible. A 2-wheeled vehicle is intrinsically of static instability, and is liable to be overturned without control. This is because the running bicycle is continuously under the influence of many kinds of disturbances. Even the bicycle’s rider him/herself is often a cause of the disturbance. Hereafter, the disturbance shall be just called noise.
