Data Observatory

Statistical patterns gathered from fitting records worldwide — body proportions, ethnic differences, size distribution and bike-model coverage.

Global Distribution

LowHigh Bubble size ∝ records

Patterns in the Data

Height distribution

Frame size distribution

Ethnic-group body-ratio ladder

Inseam-to-height ratio by ethnic group, low to high; the dashed line is the global baseline.

Frame spread at the same height

Frame map (Stack–Reach)

Each dot is one size, coloured by category: bottom-left = more relaxed (short reach, low stack), top-right = more race-ready.

Wheels: price–weight–depth

Bubble size = rim depth, colour = category; prices converted to USD at a fixed rate. Top-left = light and cheap.

On the shelf vs recommended to riders

Two rulers — top tube and frame size: shelf stock (teal) overlaid with what riders were fitted to (coral) on the same scale.

Bike Frame Library

Frame geometry collected from official sites — cm / ° units, newest first.｜ We also keep older model years of many brands in our big-data corpus — fitting results match and recommend those too. Questions? Email: friends@fittinglab.ai
