What are the different types of bike kickstands available in the market and how do they vary in terms of design and functionality?

There are mainly two types of bike kickstands available in the market: single-leg kickstands and double-leg kickstands. Single-leg kickstands are simpler in design and are usually mounted on the non-drive side of the bike. They provide basic support for the bike when parked. Double-leg kickstands, on the other hand, have two legs that provide more stability and are often used for heavier bikes or when carrying loads. They are usually mounted in the center of the bike frame. The choice between the two types depends on the weight of the bike and the level of stability needed when parked.
