About BikeFit/LAB
BikeFit/LAB is made by Geraads IT, a software company based in the Netherlands. Not a fit studio and not a physiotherapy practice, but a team that rides bikes and thought a good riding position should not cost three hundred euros.
Why this exists
A professional bike fit is worth the money if you have a stubborn complaint or train seriously. But for most riders the question is simpler: is my saddle at the right height, and am I leaning too far forward.
That is roughly eighty percent of what a studio measures, and a camera can do exactly that. So we built it. The analysis runs in your own browser, your video never leaves your device, and one measurement starts at 2.50 euros.
What the advice is based on
The target ranges we use, such as 140 to 148 degrees of knee extension at the bottom of the pedal stroke, are the same ones professional fitters work with and come from the biomechanics literature. Every article says where its information comes from, and where the research disagrees we say so.
A 2024 systematic review of knee pain in cyclists found that between 36 and 62 percent of riders experience it, and that a five percent change in saddle height alters knee movement by up to 35 percent. That last number is exactly why this product exists, because differences like that are invisible to the naked eye.
What we cannot do
A camera from the side sees your joint angles, your cadence and how much your hips rock. It does not see how your cleats are positioned, whether your saddle is the right width, or whether your legs are the same length. That needs someone standing next to you.
If pain persists after correcting your position, if it affects one side only, or if you have an injury, see a physiotherapist or a bike fitter. Our reports say the same. We optimise a position, we do not treat a body.
Who works on it
We are not certified bike fitters. We build software, we ride, and we worked through the biomechanics to build a tool that measures instead of guessing. That does not make us an authority on your body, which is why every piece of advice says where the limits are.
Questions, doubts, or a report that makes no sense to you? Let us know. At the moment we read every message ourselves.
