I built it around 2005 and it has been stored last ten years since my last son grew too old. He was in the seat until he was about five. Seat is strong and adjustable and when young kids are strapped in they can't fall out. It really is a very cool bike if you're into bmx and got kids. Seat is detachable and bike rides perfectly with or without seat fitted.Test ride is welcome before taking away if you want, and I'm listing for collection only in West Cornwall, Penzance area. Thanks for looking all you bmx mums and dads?
