Fit Series One BMX Bike 2026

Description

Fit Series One  BMX Bike 

The Series One was our first frame when we started FIT back in 2000 and it’s our most popular bike to date. For 2026 we’ve upgraded to a CNC machined Integrated headtube and a fully sealed bearing front hub. The S1 frame and fork has been lightened up and offered in 3 top tube sizes with corresponding handlebar and crank sizes.
