What are the differences between Presta and Schrader bike valves, and which one is more suitable for my bike?

Presta valves are thinner and have a built-in valve cap, while Schrader valves are wider and have a spring-loaded valve core. Presta valves are commonly found on road bikes and high-performance bicycles, while Schrader valves are more common on mountain bikes and children's bikes. The choice between the two valves depends on your bike's rim compatibility and personal preference.
