Riding with anterior knee pain, a tight lower back, or numb hands? You don't need a medical degree — you need proper geometry. Bike Fit Pro pinpoints the exact angular deviations causing injury risk and power loss.
Evaluates bottom-dead-center extension angles (the #1 factor in preventing patellar tendonitis) with sub-degree accuracy.
Balances aerodynamic efficiency against neck and spine strain according to your chosen riding discipline.
Instead of cryptic numbers, receive straightforward instructions: "Raise saddle 7mm" and "Slide saddle back 4mm".
No sensors, tape measures, or complicated setups required. Just your iPhone and your bicycle.
Mount your bike on a trainer or lean against a wall, and snap side photos at 6 o'clock and 3 o'clock pedal positions.
On-device neural vision detects anatomical landmarks: ankle, knee joint, hip, shoulder, elbow, and wrist.
Calculates critical biomechanical angles and benchmarks them against research-backed optimal ranges.
Follow clear millimeter adjustment steps, re-test anytime, and enjoy maximum comfort and pedaling efficiency.
Designed by cyclists and software engineers to bring studio-quality fitting tools to every rider.
Our machine learning models automatically identify your body joints and calculate real-time extension angles down to 0.5 degrees of accuracy. Eliminate guessing, improper ruler placement, and poor camera angles.
Select specific pain points (front knee, lower back, palm numbness, Achilles tendon) for targeted position troubleshooting.
Choose your riding objective: Race / Aero for pure speed, Endurance for grand fondos, or Casual for upright urban commuting.
Never wonder how much to adjust. Get unambiguous numbers for saddle height, fore/aft, handlebar stack, and cleat placement.
Photos are processed entirely on your iPhone's Neural Engine. Your photos never leave your device or upload to servers.
Unlock lifetime access once. Re-fit your bikes whenever you buy new saddles, shoes, pedals, or new bikes without monthly fees.
