About
MyBikeFitting brings professional-grade bike fitting to every cyclist for free. Using computer vision running entirely in your browser, the tool captures and measures the four angles that matter most for cycling comfort and efficiency: knee extension (140–150°), hip angle (55–70°), back inclination (35–50°), and arm angle (150–165°). You can analyze your position via live webcam, a recorded video, or a simple photo taken from the side. After a short questionnaire about your riding style (road, MTB, gravel) and any existing pain, the AI produces numerical adjustment recommendations for saddle height, saddle setback, handlebar position, and stem length. The methodology is grounded in peer-reviewed sports medicine research, including the Holmes method for knee extension and studies on hip compression and respiratory impact. A standout privacy feature sets MyBikeFitting apart: all image and video processing happens locally on your device. Nothing is ever uploaded to a server. The tool is available in French, English, Spanish, and German, making it accessible to a global cycling audience. MyBikeFitting is ideal for amateur cyclists dealing with knee pain, back pain, hand numbness, or neck discomfort, as well as performance-oriented riders who want to dial in their position without the cost of a professional fitting session. It is free, requires no account, and can be completed in under five minutes.
Key Features
- AI Angle Detection: Uses computer vision to automatically measure four critical cycling angles — knee extension, hip opening, back inclination, and arm bend — in real time.
- Multi-Capture Input: Supports live webcam streaming, uploaded video, or a static photo, giving cyclists flexibility to analyze their position however is most convenient.
- Personalized Adjustment Recommendations: Delivers specific numerical guidance (e.g., 'raise saddle +2 cm') for saddle height, saddle setback, handlebar height, and stem length.
- Local, Privacy-First Processing: All video and image analysis runs directly in the user's browser — no footage is ever transmitted to or stored on external servers.
- Science-Based Methodology: Angle reference ranges are derived from peer-reviewed sports medicine literature, including the Holmes method and studies on hip compression and pedaling biomechanics.
Use Cases
- A road cyclist suffering from knee pain uses the tool to discover their saddle is 2 cm too low and adjusts it based on the AI's recommendation.
- An amateur cyclist who cannot afford a professional fitting session performs a DIY analysis at home in under five minutes using only their smartphone.
- A gravel rider transitioning from road cycling fine-tunes their more upright endurance position to reduce lower back fatigue on long rides.
- A cyclist experiencing hand numbness uses MyBikeFitting to identify that excessive forward weight bias and a straight arm angle are contributing to the problem.
- A cycling coach recommends MyBikeFitting to club members as a free first-pass screening tool before investing in a full professional fitting.
Pros
- Completely Free with No Registration: Full bike fitting analysis is available at zero cost with no account creation, making it accessible to any cyclist instantly.
- Strong Privacy Guarantee: Video and image data never leaves the browser, giving users full confidence that their personal footage is not stored or shared.
- Research-Backed Accuracy: Recommendations are grounded in established scientific literature, providing credible guidance comparable to a basic professional fitting.
- Multilingual and Fast: Available in four languages with a complete analysis flow that takes under five minutes and requires no special equipment.
Cons
- Web-Only Platform: There is no dedicated mobile app; users need a browser and a stable camera setup, which can be challenging without a home trainer or assistant.
- Capture Quality Dependency: Analysis accuracy depends heavily on proper side-angle framing, lighting, and fitted clothing — suboptimal captures can reduce recommendation precision.
- No Dynamic Pedaling Analysis: The tool primarily analyzes static or near-static positions rather than full dynamic pedal-stroke motion, which professional fitters would assess in more detail.
Frequently Asked Questions
Is MyBikeFitting really free?
Yes, the entire analysis — including angle measurement and adjustment recommendations — is completely free with no subscription, paywall, or account required.
How does the AI analyze my cycling position?
The AI uses computer vision running in your browser to detect your body's key joints and calculate four biomechanical angles (knee, hip, back, arms) from your webcam feed, video, or photo.
Is my video data kept private?
Yes. All processing happens locally on your device. Your images and videos are never uploaded to or stored on any external server.
What equipment do I need for the analysis?
You only need a device with a camera and a way to view yourself cycling from the side. A home trainer is recommended for stability, but leaning against a wall or having someone help also works.
What types of pain can MyBikeFitting help address?
The tool is designed to identify position-related causes of knee pain, lower back pain, hand/wrist numbness, and neck pain — problems that account for the majority of cycling discomfort.
