In our daily life, if we had a bicycle when we were young, it was a majestic thing, but learning to ride a bicycle did bother me for a long timeWhy does cycling not fall and what is the principle of this? The answer given by scientists at the moment is due to the "gyroscopic effect" of the front wheel of the bicycle. <
Let's briefly explain what the gyroscopic effect is. Let's say you take a coin and let it roll on a flat surface. If you make it slightly inclined at the beginning, for example, give it a force to make it lean to the left When turning, when the angle of inclination becomes larger, the curvature of the turn becomes greater until the coin falls.
That's how it works, and the above explanation of the bicycle's gyroscopic effect is feasible regardless of the mechanics or the actual experience of the cyclist. Our early research on bikes focused on how to accelerate. It turns out that the design of two wheels, which is the most labor-saving and the best non-motorized mode of transport, is why it does not fall.
For more than a hundred years, the study of how bicycles stabilize has attracted many famous mechanics, physicists and even mathematicians to participate in this research. Surprisingly, so far, scientists have only given a rough explanation for the gyroscopic effect, and it is difficult to say that the problem has been solved, and people are just still working on it. Some models have been proposed for the stability of the bike, and different types of differential equations have also been listed, but one of the most influential statements is the gyroscopic effect of the front wheel of the bike.
Regardless of what the specific principle of our bicycle is not for the time being, its emergence does provide people with a lot of convenience, in this rapidly developing era, the bicycle as a means of transportation has long been replaced by electric cars, and even the more popular shared bicycles in the past two years have been forcibly occupied by many people without quality and other behaviors have led to the abandonment of businesses, so no matter what, we must take care of these means of transportation that provide convenience for our human beings.

The principle of inertia. Because the object has inertia when it is in motion, it is able to maintain the tendency of its own direction of motion. When the bicycle is riding, the whole car is moving forward, including the wheels, the rotating wheels will autonomously keep the direction of their axis of rotation unchanged, and the rotating axle will automatically keep its axis parallel to the ground, so the bicycle will not fall.
-
Because when the bicycle is moving, the wheel axle rotates like a gyroscopic effect, and it can maintain balance.
-
Because there is inertia when riding a bicycle, it is able to maintain the trend of its own direction, so as long as you maintain a good balance, you will be fine.
-
The principle of balance. Because people are in a state of balance when riding a bicycle on it, people will not fall.
-
The principle of conservation of angular momentum, as long as the rotation speed of the two wheels reaches a certain level, even if the car does not go forward, it will not fall.
-
When the bicycle is riding, the car moves forward as a whole, the wheels are also turning, and the rotating object will autonomously maintain the same direction.
-
Because the bike has two tires that can be balanced, two points are less balanced than three points, but they are also balanced.
-
Bicycles have special axles, and the movement of the axles can cause the bicycle to walk upright. This is the basic principle of force chaos and the bicycle is also set up according to this principle.
-
It is because the bicycle has a gyroscopic effect, and it also has a centripetal force, coupled with people's better balance ability, so it will not fall.
-
This is because the bicycle uses a gyroscopic effect, and when the bicycle tires are running, their centrifugal force keeps them balanced.

Because of the gyroscopic principle.
When the top rotates, it not only rotates around its own axis, but also makes a conical motion around a vertical axis. In other words, the top rotates around its axis on one side and "revolutions" around its vertical axis on the other.
The speed of the "rotation" of the spinning top around its own axis determines the size of the swing angle of the gyroscope. The slower the rotation, the greater the swing angle, and the worse the stability; The faster it rotates, the smaller the swing angle and therefore the better the stability.
It's pretty much the same as people riding bicycles. The difference is that one moves in a straight line and the other moves in a conical curve. When the gyroscope rotates at high speed, under the action of gravity, it does not fall over in the direction of the force couple, but moves in a conic around the vertical axis of the fulcrum, which is the gyroscope principle.
-
The reason why the bicycle does not fall is simple: because the center of gravity of the person and the bicycle is in a straight line, no matter which direction the bicycle is crooked, as long as the center of gravity of the person and the bicycle is the same, the bicycle will not fall.
The balance mechanism of the bike itself comes from the fork leaning back. We can observe that the handlebar axle of almost every bike, instead of being perfectly perpendicular to the ground, leans backwards. Since the front wheel is fixed to the handlebar fork, it is also called fork backward tilt.
The fork leans backwards, so that the centrifugal force generated when the vehicle turns the moment direction is opposite to the direction of wheel deflection, forcing the wheel to automatically return to the original intermediate position after deflection. In this way, the car has the stability of automatic return to the center. The faster the vehicle, the greater the recovery moment and the more stable the rider feels.

If I knew why it was dark at night and why the bicycle wouldn't fall, I would have won the Nobel Prize, and all of us don't know about it.

Objects have inertia when they are in motion, that is, they have a tendency to maintain their own direction of motion.
When the bicycle is riding, the whole car is moving forward, the wheel itself is also rotating, the rotating object will autonomously keep the direction of its axis of rotation unchanged, when it is normal not to fall, the axis of rotation of the wheel is parallel to the ground, if it is tilted, the axis of rotation of the wheel is oblique to the ground, and the axis of rotation when riding will automatically keep its axis parallel to the ground, so it will not fall.
-
The reason why the bicycle does not fall when it is moving: objects that rotate at a certain speed have the ability to keep the direction of the axis of rotation unchanged, so that they do not fall to the sides.
Analysis: When riding, it is to give the bicycle a force in the direction of progress, so that the wheels can rotate, the wheels can maintain a certain state of balance, and then use the handlebar to adjust the balance, and the bicycle can go forward. But as soon as it stopped, the car would lose its balance and fall over.
Under normal circumstances, one meter four is actually about the same when you start a pedal bike. You can buy him some small ones.
The reason for this phenomenon is actually that there are many laws in the United States, which stipulate that helmets must be worn when riding bicycles and motorcycles. >>>More

In the progress of human society, many time-saving and efficient tools have been invented, providing a lot of convenience to people's lives, and bicycles are one of them. With bicycles, the same distance is not only shortened a lot, but also saves a lot of effort to walk. Cycling is much less labor-saving than walking, there are several factors that decide, the most critical factor is that when people walk, in addition to bearing the friction between the soles of their feet and the ground, as well as bearing the weight from themselves, these will consume body energy, resulting in physical fatigue, cycling will be much easier. >>>More
