Nahum Billington 20" Sunday Radocaster BMX Bike Check

Nahum Billington is a rad 13 year old BMXer from Canada. Nahum just transitioned from an 18″ to a 20″ Sunday Radocaster build. BMX Groms worked with him to build the bike and document the size change for an upcoming feature on BMX Groms. We used as many parts from the 18″ as possible to help the transition. The 20″ Radocaster frame is a good choice for your first 20″ BMX. The Radocaster frame features excellent quality at an affordable price, which is important when you are still growing and may move up to a larger frame in the future. Learn more about this frame on Sunday Bikes. The 20.5″ top tube length is a good entry point into the 20″ size. For more info on BMX sizing, peek our sizing guide.
