Product Description

Fly's Sion was built as the perfect ramp-blasting machine, equally capable of handling business when it comes to heavy street riding.

With help and input from Larry Edgar, Josh Dove and Sergio Layos the Sion has been built for speed and riding control, with an absolute ton of aftermarket Fly parts, like Fuego Tyres, Volcano Stem, Sierra Seat and more Ruben parts.

A full chromoly frame, forks and bars ensure reliable durability from the Sion with front and rear sealed hubs, a 3-piece crankset and chain tensioners helping the rest of this setup feel solid.

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!
