What it does
Three readings, taken at the moment your leg is actually straightest.
Saddle height, fore and aft, position.
From one side-view video, Bike Fast Fit EZ gives a millimeter change for saddle height, a millimeter change for fore and aft, and your riding position: Upright, Relaxed, or Aggressive.
Just your phone, no markers.
Bike Fast Fit EZ reads your body off 240 fps slow-motion video with markerless AI tracking. No dots to stick on, no studio, no extra gear.
A dashboard you flip through.
Height, fore and aft, and position each get their own page, with the recommended change shown plainly. A full check takes about a minute.
Read at Maximum Knee Extension.
Bike Fast Fit EZ measures your leg at its true straightest point near the bottom of the stroke, not a fixed bottom point, so the numbers match how you actually pedal.
Kept deliberately simple
Bike Fast Fit EZ does one thing well: a fast self-check. Side view only, no rider or bike profiles, and crank length set to 172.5 mm. If you want front view, the full measurement suite, or client records, that is Bike Fast Fit Elite and Pro. Moving up later? Elite asks whether to bring your BFF EZ fits over, and they come across.
