Road bikes don't have kickstands because they are designed with aerodynamics and riding comfort in mind. Here are some reasons:
1. Aerodynamics: In road bike racing, aerodynamic performance is very important. Kickstands increase the drag of the bike and reduce riding speed. Therefore, designers removed kickstands to reduce air resistance and increase riding speed.
2. Comfort: Although kickstands can provide a certain degree of stability, they also increase the weight of the bike and affect riding comfort. In addition, kickstands may cause discomfort on bumpy roads. Therefore, designers choose to remove kickstands to improve riding comfort.
3. Safety: Many road bikes are equipped with very narrow tires, which already reduces the stability of the bike to a certain extent. If kickstands are added, the stability of the bike may be further reduced, increasing the risk of accidents.
4. Maintenance and storage: Road bikes usually need to maintain a low center of gravity to maintain stability when riding at high speeds. Kickstands increase the center of gravity of the bike, which is not conducive to maintenance and storage.

In short, the main reason why road bicycles do not have kickstands is to reduce air resistance, increase riding speed and comfort, and ensure the safety and easy maintenance of the vehicle.
