Mountain bikes generally don’t come with kickstands because they are designed for off-road riding and are not typically used to park or stand upright for long periods of time. Kickstands are commonly found on other types of bikes, such as city bikes and cruisers, which are designed for leisurely rides and may be parked or stored for extended periods.
One reason mountain bikes don’t have kickstands is that they are typically designed to be lightweight and efficient, and a kickstand adds unnecessary weight and complexity. In addition, kickstands can get in the way or cause problems when riding off-road, such as getting stuck in the ground or catching on obstacles.
Another reason is that mountain bikes are often used in rough, uneven terrain, and a kickstand may not provide a stable base for the bike to stand on. Instead, mountain bikers often lean their bikes against a tree or other object, or they may use a bike stand or wall-mounted rack to store their bikes when they are not in use.
