It is difficult to control the balance between speed and safety when riding fast. Is there any way to improve it?

My suggestion is to change a comfortable and stable riding cushion. In fact, you and I had similar troubles some time ago. Later, I was recommended by a friend to change it to velo 3 147. This cushion is relatively wide, but the design will not rub my thighs. The shock-absorbing foam in the cushion makes the riding process more comfortable, ensuring faster speed and safer.
