Radio Saiko 18" BMX Bike
Radio Saiko 18" BMX Bike
-
The Saiko now comes in an 18" version, for all those younger riders who want a low-slung BMX with slightly shorter geometry then this is the bike for you.
Radio utilise both 1020 hi-ten steel and crmo in the Saiko's construction to ensure a perfect balance between weight and durability.
It's a ridiculously fun bike that features 25/9 gearing, a sealed mid bb, an integrated headset and the ever popular Salt Tracer tires. All of that results in what is easily one of the most stacked 18" bikes on the market.

BMX BIKE SIZE GUIDE
BMX bikes are measured in two ways: the size of the wheel (20” is the standard BMX wheel size), and the length of the frame which is gauged by the top tube measurement. We have also simplified for you into XS, Small, Medium, etc.Here is a guide to what size you should be looking for - note that there is some overlap in sizes, as personal preference also comes into the equation!
