Radio Saiko BMX BikeIf you're looking for something a little more nimble and responsive or find that a full sized 20" BMX is too big for you then the Saiko may be what you're looking for. It is a style that has evolved over time to become a low slung 20" bike with shorter geometry making it way more responsive than a regular 20". It's built with durability in mind with 1020 hi ten steel frame, forks and bar each with chromoly used in places to add additional strength.
