Principle of bicycle bracket Why can't a single tree roll over after it is equipped with a bracket?

The principle of bicycle bracket is that triangle has stability.

Whether it is a one-legged leg brace or a two-legged leg brace like a motorcycle, it will form a triangle when supporting a bicycle.

If it is a one-legged foot brace, the foot brace and the front wheel landing point and the rear wheel landing point form a triangle on the ground, and the vehicle leans towards the foot brace to ensure that the projection of the center of gravity on the ground is within this triangle.

If it is a two-legged leg brace, the landing point of the two legs and the front wheel form a triangle. The principle is the same as above The stability of the two legs is better, and it will be more scientific in practical use. Whether it is supporting or pushing away, it will be more labor-saving. There is basically no need to worry about crushing the bracket because of too much load, and one leg may bend.
