Page 16: Braking System
Saddle angle: In order to avoid leaning forward when riding, it is appropriate for the front end of the saddle to lean upward, the front and rear position can be appropriately adjusted based on individual height. Minimum height of the saddle: move the quick release handle to the OPEN position, then put the saddle post to the lowest place, and when the saddle post cannot enter into the saddle tube of the frame, it is the minimum height of the seat.

*Braking skills: as we all know the principle of hard braking is first stopping the rear brake then the front brake. But in case of an emergency, everyone will stop all together. If the braking distance is appropriate, the bike can stop securely; if the slowdown is too fast, people often would be thrown forward and in order to prevent this danger, the best way is intermittent braking, and meanwhile the hip is pushed backward.
