The bicycle is tilted, why can't it be picked up if it is tilted?

The problem of the subject is that the bicycle is inclined. Why can't you step on it when you are leaning? Because when the head is tilted, the center moves backward and the ass hangs behind the seat, so you can't step on it after tilting. The solution that the bicycle can't step on the head;

1. First, give the front of the car a downward force to press the handlebar, and then lift it by the rebound force, so that the front fork can be locked.

2. When lifting the front of the car, the body should sit back and shift the center of gravity to the back of the seat cushion. After sitting or not, the center of gravity is still in the front triangle of the frame, so it is naturally difficult to pull it up.

3. Lift the front of the car with a small gear ratio when riding. For example, the front of the chain is on the middle toothed plate and the back is on the third and fourth flywheels. At this time, the speed is low and the trampling frequency is high. The front of the chain is on the big toothed plate, and the back is on the 1 and 2 flywheels, with high gear ratio and high speed mode.
