Live fit
Prop your phone side-on, hop on, and pedal. We measure your joint angles in real time and lock in a result the moment we've seen enough clean pedal strokes. The raw video never leaves the screen — only the joint-angle measurements are saved, on this device.
Link this fit to a bike (optional)
Choose a local bike to keep this camera result in its history. Nothing is uploaded, and you can always continue without a profile.

One quick check before we start
OpenBikeFit is for comfort and performance — not medical care. Do any of these apply to you right now?
- Have you had a crash, fall, or direct injury in the last few weeks?
- Is your pain severe, or steadily getting worse over time?
- Does the pain wake you at night or is it worst when resting?
- Is the pain clearly present even when you are off the bike?
- Do you get genital or perineal numbness that lingers after you stop riding?
- Any radiating numbness, pins-and-needles, or weakness in your legs, feet, arms, or hands?
- Any limb that goes cold, pale, or pulseless, or cramping pain that forces you to stop?
- Do you have a marked leg-length difference or obvious one-sided asymmetry?
- Are you currently unable to pedal without significant pain?
“None apply” is one explicit attestation covering all nine items listed above. If any answer is yes or uncertain, the full screen records each answer separately and pauses automated fitting when appropriate. OpenBikeFit is a fit-and-comfort tool, not a medical device. It does not diagnose or treat any condition.

The full guided fit adds your bike details, symptoms, and mobility self-checks so the suggestions are tailored to you. The live result is a great first pass.
