For the best result
- Film from the side, showing your full body and bike
- Good light and a steady camera position
- Pedal at your normal cadence for about a minute
- Wear form-fitting clothing so your joints are visible
- Include both seated and standing positions if you can
Your video stays on your device. Pose detection runs in your browser; only the measurements are sent to write your coaching summary. If you save the result to an account, we keep the results, not the video.

What the basic analysis measures
- Knee angle at the bottom and top of the stroke — saddle height
- Hip angle — saddle position and reach
- Torso lean — handlebar reach and height
Knee tracking, left/right symmetry, pedaling efficiency and fatigue are in the advanced analysis.
