Why is it easier to balance a bicycle while it’s in motion?

Question

I never quite understood why it is so much easier to keep a bike balanced while riding at a certain speed, compared to riding it really slow, or while standing…

Answer 1

The position of the front wheel relative to the steerer tube (the part of the frame at the front between the handlebar and the wheel) causes the front wheel to ‘want’ to turn in a direction that will keep the bike from falling over.

You can see this by pushing a bike with your hand on the seat. It will tend to stay upright, and you can steer it by leaning it one way or the other.
