The Series One was Fitbikeco's first frame back in 2000! It was a
straight-forward, clean BMX frame that helped re-define what was
necessary and what wasn’t. Twenty-three years later, the Series One is a
high-quality complete bike with everything entry level riders need and
nothing they don’t. With three Top-Tube sizes and proportional
components there’s an S1 for anyone looking for a 20” BMX bike.
Responsive but stable geometry, traditional fork off-set, and
comfortable 2-pc bars, these bikes work for any style of riding.
