Enter simple body metrics and riding style. This client-side tool returns recommended saddle height, frame-size range, and handlebar height/angle. No external APIs required.
Saddle height: uses the LeMond formula — saddle = inseam × 0.883. If you don't know your inseam we estimate inseam = height × 0.46 (typical adult proportion) then apply the formula.
Frame size: gives approximate frame size ranges based on standing height and bike type. These are general guidelines — brand geometry varies.
Handlebar height & angle: recommended relative to saddle based on riding style (upright vs aggressive vs trail).
