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.
