How to Change a BMX Seat

The shape and weight of a bike seat affects the comfort of the rider and varies depending on what you use the bike for. BMX riders like to be able to customize their bikes by adding different seats and handlebars for image and practicality (for example, to make the bike lighter). You can change your BMX seat with a set of Allen keys, which you can get in most hardware and bicycle shops.
