A great entry level 16" wheeled BMX bike from the Huffy. The Symbol features smaller 16" wheels than a standard BMX and a short 16.75" top tube frame to suit riders typically between 4-6 years old (or 90-110cm tall). This little BMX is a great and cost-effective option to get started in BMX and is packed with solid and dependable components which are all upgradable with after-market parts if you need - there's no weird compatibilty issues here.
