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.
