We all know that riding a bicycle is very easy. It comes so natural! In fact, like the old saying goes: “it is even easier to ride it than to fall off one”. And of course, once you learn it, you will never forget how to do it! Bicycles can stay upright even without any human intervention when they are set in motion at a sufficient speed. But the most intriguing thing here is that knowing why you can ride a bike is harder than actually doing it.
How can a bike remain stable whilst other two-dimensional objects just fall over? Understanding the physics beyond this two-wheeled transport method can be a bit more complicated. But to put it simply, bicycles become stable whilst in motion due the gyroscopic effect of the spinning front wheel. Another accepted view is that the front wheel “trails” behind the steering axis. These two views are not in contradiction, and it is probably sensible to accept both of them as the reason behind the stability of a bike whilst in motion. But try not to think too much about it whilst you are ridding your bicycle haha. Just do it!
