Common questions
Is an AI bike fit accurate enough?
AI bike fitting is useful for checking common setup issues like saddle height, reach, and visible posture problems. It is not a medical diagnosis, but it is a strong first pass before paying for an in-person fit.
What do I need for an online bike fit?
You need a phone or camera, good lighting, fitted cycling clothing, and a stable bike setup. A trainer gives the best result because your riding position stays repeatable.
Which bike fit should I start with?
Start with saddle height because it affects knee angle, hip comfort, and the rest of the fit. Then check saddle offset and cockpit reach.
