You aren’t a size. Your bike shouldn’t be either.
No S, M, or L. No 54 or 56. Every Heiden starts with your body’s proportions and the way you want to ride — road, gravel, or anywhere between. 3D-printed steel or titanium lugs, bonded to carbon tubing, built around geometry that’s entirely yours.
Your frame. Your ride.
Most bikes are built for an imaginary average rider. A Heiden Frameset is built around you — adaptive geometry driven by your body’s proportions, not a size chart. Pick anything from a 30mm slick to a 2.4″ mountain tyre, handling from stable to agile — everything is down to you.
See the model in 3D.
Orbit, zoom, and inspect the actual production frame — not a concept or prototype, the real CAD geometry.
Built from personal frustration.
I spent years unable to fit on standard bikes — adjusting stems, swapping cranks, spending money trying to make something work that was never designed for me. In 2011 I started ordering my own frames built to spec, and everything changed.
You don’t have to be an outlier to be failed by the bike industry. Heiden exists for anyone who’s ever felt like bikes just weren’t made for them.
