Why Pedalyze
Everything a bike fitter checks by eye, measured for you.
Automatic joint detection
Pose estimation finds your hip, knee, ankle and shoulder — no manual markers needed.
Fit angles that matter
Saddle height, knee flexion and KOPS, measured directly from your riding position.
Compared to standard ranges
Every angle is checked against ranges used by professional bike fitters.
How it works
Three steps, under a minute, no equipment beyond your phone.
Take two photos
Side-on, pedal at 6 o'clock and, optionally, crank horizontal at 3 o'clock.
Pick your fit style
Road, endurance, or another profile — Pedalyze adjusts target ranges accordingly.
Get your results
