Growing up, I always thought that a bicycle remained upright due to the gyroscopic nature of the spinning wheels. The pesky fact that bicycles remain stable even at very low speeds? Ignored it.

Now I know better. The majority of the stability comes from the geometry of the bicycle. In essence, a falling bike causes a steering deflection that moves the center of gravity back underneath the bike and stops the fall.

Some Brit made a special bike with a counter-rotating wheel, just to prove the point. The bike remained rideable.
