Description
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.
