Frequently Asked Questions
Everything you need to know about BikeFit AI
BikeFit AI uses computer vision to analyze your cycling position via a simple video. The algorithm detects your joint landmarks in real-time and calculates critical biomechanical angles (knee, hip, shoulder, elbow) to provide you with personalized adjustment recommendations. A conversational AI Coach then guides you to deepen your analysis and answer your questions.
BikeFit AI supports all disciplines: Road, Gravel, MTB, Enduro, Triathlon and Time Trial. Each discipline has its own optimal angle ranges and specific recommendations adapted to your goals (performance, comfort, aerodynamics).
Film yourself from the side (lateral view) on a indoor trainer. Minimum duration: 30 seconds. Recommended resolution: 720p, maximum 4K. Accepted formats: MP4, MOV, AVI, WebM. Maximum size: 150 MB.
Yes, BikeFit AI is fully GDPR compliant. Your video is deleted immediately after analysis. If you save your analysis, only joint landmarks (anonymous coordinates) are stored, never the video. You can delete your data at any time from your account.
Absolutely! BikeFit AI is compatible with all browsers (Chrome, Safari, Firefox, Edge) on smartphone, tablet and computer. You can film directly from the application and analyze your position on a indoor trainer.
Our computer vision algorithm detects your joint landmarks at 60 frames/second, over 1800 measurements in 30 seconds of pedaling. Accuracy is ±5° per joint — this is the physical reality of any video-based pose analysis, regardless of the tool. No video-based system can scientifically prove higher accuracy. At BikeFit AI, we'd rather be upfront about it: our algorithm automatically filters measurement noise to show you only real changes in your position. Each diagnosis is tailored to your discipline and goals.
BikeFit AI provides a complete biomechanical analysis including pain detection, with precise adjustment recommendations tailored to your profile. This is sufficient for the vast majority of cyclists. For complex cases (pathologies, significant asymmetries), we recommend consulting a professional as a follow-up. Your BikeFit AI report will be an excellent starting point for that consultation.
BikeFit AI analyzes your cycling position from the side (left or right profile). This is the view used by professional bike fitters to measure your joint angles (knee, hip, shoulder, elbow, torso). Front or rear views are not supported. For asymmetry issues (such as a leg length difference), we recommend consulting a bike fitter in person.
Before launching your analysis, specify your context: pain, goals, equipment changes. The AI Coach adapts its entire diagnosis to your situation. This is a unique feature — no other bike fitting solution offers this.
How It Works
A simple 3-step process for complete analysis
AI Coach
Personalized report
Position analysis
For your endurance goal, your knee extension is slightly insufficient. Gradually raise your saddle to improve efficiency without sacrificing comfort.
Pedaling style
Moderate ankling detected. Your ankle compensates for the lack of extension — the saddle adjustment should naturally correct this.
Priority adjustment
→ Saddle: gradually raise the height. This will improve your knee extension and reduce ankle compensation.
