How the rider on the bicycle maintains its balance in moving condition?

Answer 1

The wheels on the bicycle are moving with considerable velocity. The angular momentum of the wheels are of a magnitude in a direction perpendicular to the left of the rider.

The faster the rider is pedalling, the greater the angular momentum will be, and it will resist any small effort to throw the rider off balance.

This can be easily shown by extending an axle through a model wheel, suspending the wheel and then spinning the wheel from a vertical position. The wheel will not droop down as the angular momentum will maintain its uprightness.

Similarly, you can roll a quarter or a hoola hoop - roll it faster and it will maintain its balance for longer.

Answer 2

The reason you stay balanced is because there's positive stability in the system. What this means is that if you start falling to the right the bike automatically turns to the right which in turn puts you back into balance.

The way this works is through the rake of the front wheel, it sticks forward at an angle from your bike. As a result the point of contact on the road is behind the pivot point of the handle bars and steering wheel. When the bike leans over, a lateral force is placed on the tire contact point. This then places a torque on the wheel and handlebars causing the bike to turn into the lean. The centripetal force from the turn then pushes the bike back to a level riding position.

Answer 3

It's a closed-loop control system that your subconscious mind is so good at, you no longer need to think about it. When you sense that you are starting to lean toward the right, you turn the wheel slightly to the right. This applies a righting force and also repositions the contact point with the ground to be again directly below your center of gravity. The wheels have too little mass and move too slowly to have any significant gyroscopic stabilizing effect. It's just enough to counter any tendency for the front wheel to turn on its own.

Answer 4

By practice as often as you could.
Try to ride as slowly as you could, stop if you could without your feet on the ground. The longer your feet are off the ground, means you get more balance to ride a bike.

Answer 5

the turning wheels act as gyroscopes
