What is MyBikeFitting AI Posture Analysis?

MyBikeFitting offers a revolutionary, completely free online bike posture analysis powered by Artificial Intelligence. Designed for cyclists of all disciplines—road, mountain bike (VTT), gravel, or indoor training—this tool analyzes your current cycling position using only a webcam, video, or a simple photograph. The core purpose is to quickly identify biomechanical issues that commonly lead to pain points such as knee discomfort, back pain, or hand numbness, providing immediate, actionable, and quantified adjustments for your setup.

Unlike traditional bike fitting services that require appointments, specialized hardware, and significant investment, MyBikeFitting leverages advanced computer vision technology to measure critical joint angles in real-time, directly on your device. This ensures maximum privacy, as your images and videos never leave your local browser. By focusing on key metrics like knee extension, hip angle, back inclination, and arm angle, the system delivers precise recommendations for saddle height, setback, and handlebar position, making professional-grade ergonomic assessment accessible to everyone.

Key Features

• 100% Free and No Registration: The service is entirely free to use, requiring no sign-up or commitment.
• AI-Powered Analysis: Utilizes sophisticated algorithms to analyze joint angles from standard photos or live webcam feeds.
• Privacy Focused: All processing occurs locally on the user's device; images and videos are never uploaded or stored on external servers.
• Quantified Recommendations: Provides specific numerical adjustments (e.g., "Saddle +2cm") based on four key angles critical for performance and comfort.
• Pain Detection Mapping: Directly correlates common cycling pains (knee, back, hands) with specific positional faults.
• Scientific Methodology: Angle ranges are grounded in established biomechanical literature (e.g., Holmes et al., Millour et al.).
• Multi-Discipline Support: Tailors initial questionnaire inputs for Road, MTB, Gravel, Triathlon, and Indoor cycling practices.

How to Use MyBikeFitting AI Posture Analysis

Getting your free analysis is a straightforward, three-step process that takes approximately five minutes:

1. Questionnaire (01): Begin by answering a brief survey detailing your cycling discipline, current pain points, fitness goals, and general morphology. This customizes the subsequent analysis.
2. Capture (02): Choose your input method: live webcam stream, pre-recorded video, or a static photo. For best results, ensure good, uniform lighting, wear fitted clothing, and place the camera perpendicular to your bike at saddle height, ideally capturing the right side of the drivetrain.
3. Settings & Results (03): The AI instantly processes the image, measuring the four key angles. You will immediately receive detailed, explained recommendations for adjustments to your saddle height, setback, and handlebar setup, helping you optimize your position for comfort and efficiency.

Tips for Accurate Capture: Place the pedal at the bottom dead center (6 o'clock) for accurate knee extension measurement. Ensure the entire bike and rider are visible in the frame.

Use Cases

1. Diagnosing Chronic Cycling Pain: Cyclists experiencing persistent knee pain, lower back strain, or numbness can quickly pinpoint the most likely positional cause (e.g., incorrect saddle height causing knee issues) without an immediate, costly in-person visit.
2. Pre-Ride Setup Verification: Before a major event or long training block, riders can use the tool to quickly verify if their current setup aligns with optimal ergonomic standards, especially after swapping components or moving bikes.
3. Beginner Setup Guidance: New cyclists who are unsure how to set up their first bike correctly can use the free analysis to establish a safe and efficient starting position, avoiding the development of bad habits or early injuries.
4. Indoor Trainer Optimization: Users training primarily on a home trainer can ensure their static setup is optimized for long indoor sessions where minor discomforts can become major issues.
5. Quick Component Adjustment Check: When installing a new saddle or stem, this tool provides immediate feedback on whether the new component placement falls within recommended angular parameters.

FAQ

Q: Is the MyBikeFitting analysis truly 100% free? A: Yes, the analysis is completely free. The service is offered without charge because the computation runs entirely on your local device, eliminating server hosting costs, allowing us to provide this technology at zero cost to the user.

Q: What are the four key angles measured, and why are they important? A: We measure Knee Extension (crucial for saddle height), Hip Angle (affects power and breathing), Back Inclination (determines aerodynamics vs. comfort), and Arm Angle (impacts shoulder and hand comfort). These angles are fundamental to cycling biomechanics.

Q: Can this replace a professional, in-person bike fit? A: While the AI provides excellent, scientifically-backed baseline recommendations, it is a screening tool. For complex biomechanical issues, severe pain, or professional competitive needs, consulting a certified professional bike fitter remains recommended.

Q: What is the minimum requirement for a successful capture? A: You need a stable camera position, good, even lighting (avoiding harsh shadows or backlighting), and fitted clothing to clearly define joint locations. A home trainer is recommended for stability, but leaning against a wall can suffice.

Q: Do I need to create an account or provide personal data? A: No. The analysis is designed to be anonymous. Your images and videos are processed locally and never transmitted off your device, ensuring complete privacy without requiring any registration.
