Creating a higher end 18″ bike last year was a risk not many people would take, and the fact it is back for 2013 mean it was for good reason. The United Supreme SU18 2013 is tailored to the smaller rider that is serious about progressing on a bike and having something that will hold up to their steep learning curve. We researched and developed how we could continue to have this model ride like a scaled down 20″, responsive pro level frame geometry that we tweaked from last year, larger 7.25″ rise bars, along with our own shorter grips, lever and stem keep this sized perfectly. What you won’t find on many other 18″ bikes is a Japanese cromo main frame, 100% cromo forks and a fully sealed rear cassette. If you are young, but serious about BMX then this is the bike for you.
