Bike Fast Fit
Compare the three apps
Each app is its own download. Elite and Pro share one library, so your sessions are already there when you install Pro. Your Pro subscription or trial has to be active first, or Pro has nothing to read.

How all three work
Markerless AI on slow-motion video
All three read your body from 240 fps video with no markers. Bike Fast Fit Pro can add an optional marker override for hard cases.
Measured at Maximum Knee Extension
We read at the true straightest point near the bottom of the stroke, not a fixed bottom point.
Calibrated from your crank length
Real millimeter numbers come from the crank arm. Bike Fast Fit EZ assumes 172.5 mm; Bike Fast Fit Elite and Pro let you enter it.
Your data moves up with you
No in-app upgrade. Coming up from BFF EZ, Elite asks whether to bring your existing fits over, and they come across. Elite to Pro needs no move at all, because the sessions are already where Pro looks.
