Bicycle seats on the market are roughly divided into wide and large seats, narrow and slender rigid seats, and wide and short-nose seats.
The wide and large seat is suitable for slow and long-distance users. There is a large and even support surface between the seat and the buttocks, which provides better comfort on long journeys. 
Narrow and slender hard seats are common on road bicycles. When pedaling at high speeds, the wide seat will rub against the inner thighs, which can easily cause skin damage and pain. Therefore, the slender and streamlined seat design was born.
The wide + short nose seat has become popular among road cyclists in recent years. The short-nose seat originated from UCI competition rule 1.3.013, which stipulates that except for track cycling sprint events, the horizontal distance between the nose tip of the seat and the vertical line in the center of Sumitotsu must not exceed 5cm for participating vehicles in other competitions. If there are special physical circumstances (such as a driver who is too short), an application needs to be made during the event vehicle inspection. The earliest use of short-nosed or no-nosed sitting positions began with the triathlon. The purpose is to enable athletes to remain in the TT (timetrial - time trial) position for a long time and avoid discomfort in the driver's lower body. In addition, the wide + short nose design combines the advantages of increased blood flow and high pedaling efficiency, making it suitable for cyclists who do not frequently change their pedaling posture.
