## What is BikeFit AI?

Get instant bike fit feedback — no appointment, no equipment, just your iPhone.

BikeFit AI uses Apple's on-device pose estimation to analyze your cycling position from a simple side-view video. Record yourself pedaling on an indoor trainer for 30 seconds, and receive a detailed breakdown of six key biomechanical metrics used by professional bike fitters.

WHAT YOU GET
• Knee Extension & Flexion — assess whether your saddle height supports efficient pedaling
• Hip Angle — evaluate your reach-to-stack ratio and hip flexor comfort
• Back Angle — understand how aggressive or upright your riding position is
• Elbow Angle — check your handlebar reach and vibration absorption
• Ankle Angle (Heel Drop) — see if your foot position is neutral at the bottom of the pedal stroke

Each metric includes a clear traffic-light rating (green, yellow, red), your measured angle in degrees, and the ideal range for your riding style.

HOW IT WORKS
1. Set up your phone at hub height, side-on to your trainer
2. Follow the on-screen guide to frame yourself correctly
3. Pedal steadily for at least 30 seconds
4. Get your results in under 20 seconds

TWO RIDING MODES
• Endurance — relaxed geometry ranges for long-distance comfort
• Performance — tighter ranges for aggressive, race-oriented positioning

UNDERSTAND, DON'T GUESS
Every metric comes with educational context: what was observed, why it matters biomechanically, and what a professional bike fitter might consider. BikeFit AI teaches you about your position — it doesn't prescribe changes.

TRACK YOUR PROGRESS
• Session history with date-stamped results
• Side-by-side comparison of any two sessions
• Shareable report images with annotated key moments

100% PRIVATE
All analysis runs entirely on your device using Apple's Vision framework. Your videos are never uploaded. No internet connection is required. No account needed.

KEY FEATURES
• 6 biomechanical angle measurements
• On-device AI pose detection — works offline
• Video replay with skeleton overlay
• Annotated key-moment snapshots (top & bottom of pedal stroke)
• Standard (fast) and Detailed (precision) analysis modes
• Import existing videos from your photo library
