FIT Series One Complete BMX Bike - Gloss Smoke Chrome 20.5" TT

The Series One was the first frame when FITBIKECO started back in 2000 and it’s their most popular bike to date. For 2026 they'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.
