  • The Sion BMX from Fly is inspired by team rider Courage Adams and is fully loaded with great parts and innoation which we hae come to know and love from Fly. The Sion is built around a responsive full 4130 frame and is laoded with Fly signature parts like the Roey 2 Stem, Devon Smilie Tripod seat, Fuego tires and Ruben pedals. The rest of the parts are taken care of by Fly and Trebol and nothing has been over-looked - theres even 2x Nylon hub guards.

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!
