Kickstands are a popular accessory for bikes, but whether or not you should put one on your bike depends on the type of riding you'll be doing and your own personal preferences.
Kickstands can be a convenient addition to a bike, as they allow you to park your bike upright without having to lean it against something. This can be especially useful when you're out and about and don't want to leave your bike lying on the ground. Kickstands are also useful for people who have difficulty balancing a bike when it is not in motion.
However, it's important to note that kickstands can also add weight and complexity to a bike. They can also get in the way when you're riding, and they can be prone to getting caught on obstacles. Additionally, kickstands can be less stable than leaning a bike against something, and they can be more prone to falling over if they are not used correctly.
Many road and racing bikes don't have kickstands because they are designed to be lightweight and fast. A kickstand is an additional weight that will slow down the bike and cause extra drag. Additionally, road and racing bikes have a geometry that is not compatible with a kickstand, it would negatively impact the handling and stability of the bike.
Many mountain bikes also don't have kickstands because they are designed for off-road use. Kickstands can get in the way when you're riding on rocky or uneven terrain, and they can be more prone to getting damaged. Additionally, many mountain bikers prefer to lean their bikes against a tree or a rock when they take a break, as this can be more stable than using a kickstand.
In conclusion, whether or not you should put a kickstand on your bike depends on the type of riding you'll be doing and your own personal preferences.
