A high-quality first-pass fit from your phone. We track how you actually move across dozens of pedal strokes, rate our confidence honestly, and hand off to a human when that's the right call.

The principles a great fitter works by — encoded into a transparent engine.
Most tools reduce you to one knee angle in one frame. OpenBikeFit measures many pedal cycles and weighs them against your goal, symptoms, mobility, and the cycle-to-cycle variability — then tells you how sure it is.
Every reading carries a confidence band. Too noisy? We ask for a better clip — never invent a millimetre.
Everything runs and stays on your device. No account, nothing uploaded — unless you ever turn on sync.
A red-flag screen runs first. Severe, neurologic, or off-bike symptoms pause the fit and point you to a human. Not a medical device.
Re-record after an adjustment and we compare before/after — only calling it an improvement when it beats measurement noise.
Installable as an app. Once loaded, the whole fit runs without a connection — in the garage, basement, anywhere.
About ten minutes, start to finish — stop and resume any time.
Discipline, goals, symptoms, setup. A safety screen runs first — some things belong with a clinician, not an app.
A guided, side-on clip. We score the video quality before analysing — a bad clip is rejected with reasons, not a fake answer.
Small, reversible suggestions with the reasoning shown. Make a change, re-record, and we confirm whether it helped.
