Bike Fitting
Upload a side-view photo or video of one rider cycling. Best results come from a camera placed perpendicular to the bike, with the full rider and bike visible in the frame. Backfround should be as uniform as possible. After initial detection, joint markers can be manually moved on a photo or paused video frame. If the joint is not found, try adjusting the joint markers manually.
Recommended ranges are meant for road bike, with hands on hoods. Position the crank at 12:00 (top) to check minimum hip and knee angles. Position the crank at 6:00 (bottom) to check maximum hip and knee angles.
Upload
Choose a photo or video from the side of the rider. Use one rider, steady lighting, and keep the bike centered.
Angles
How to record a bike fit photo or video
Place the camera level with the rider, directly from the side, and far enough away to include the full rider and bike. A trainer setup usually works best because the rider remains in a fixed position.
This tool estimates joint landmarks and measures visible body angles. Treat the results as an analysis aid, not a professional medical or bike fit diagnosis.
