Why it's Easy to Balance a Moving Bicycle?

Balancing a bicycle while it is in motion may seem like a difficult task, but it is actually quite simple when you understand the physics behind it.

When a bicycle is in motion, its wheels are moving in a straight line. This means that the center of mass of the bicycle is also moving in a straight line. As long as the bicycle is moving forward, the wheels will remain stable and the bicycle will remain upright.

However, if the bicycle begins to tip to one side or the other, the wheels will no longer be moving in a straight line. This will cause the bicycle to begin to rotate, which will cause the center of mass to move in a curved path.

At this point, the rider must make a small correction to their body position in order to keep the bicycle upright. This correction is called "countersteering," and it involves leaning the body in the opposite direction of the desired turn.

For example, if the rider wants to turn left, they will lean their body to the right. This will cause the bicycle to rotate in a leftward direction, and the wheels will once again be moving in a straight line. This will keep the bicycle upright and stable.

In conclusion, balancing a moving bicycle is easy because the wheels are moving in a straight line. As long as the rider makes small corrections with their body position, they can keep the bicycle upright and stable. This simple principle of physics makes it possible for even a child to ride a bicycle.
