An online bike fit is a digital service where you answer questions about your body, bike and cycling goals from home. An algorithm, developed by bike fitters, a sports physician and a mathematician based on peer-reviewed research, calculates your ideal saddle height, saddle setback, and the horizontal and vertical distance from your saddle to the handlebar. The report also provides instructions for setting up the touchpoints themselves (cleat position, saddle tilt, saddle width, handlebar width, crank length), and feeds into our free Bike Setup Tool to translate the fit into a matching frame size and cockpit setup for any specific bike model. You receive a PDF report with exact numbers in millimetres and apply the changes yourself with basic tools. Cost: €12.50 instead of €200+ for a physical fit. Time: ~15 minutes. Reliability: comparable to a physical fit for 95% of riders, except in cases of serious physical conditions such as a leg-length difference or a severe spinal condition. In those cases a physical assessment and bike fit is recommended.
Why do an online bike fit instead of a physical one?
A physical bike fit costs €200–€450 and means travelling to a studio, taking time off, and being measured in a lab. An online bike fit gives you the same outcome (the right position numbers) without any of that friction. Our tool is developed by bike fitters, a sports physician and a mathematician, grounded in scientific research.
Save €200 vs. a physical fit
Pay €12.50 instead of €200–€450. Same biomechanical logic, no studio overhead.

Expert Reviews:
KARIN KASTELIJN
Sports Physician
"I was very surprised by the accuracy of this advice. I do dynamic bike position measurements myself. I have compared my advice several times with the results of this online advice, and they were always very close to each other."
For people with special issues, I do recommend getting a personal bike fitting. I don't believe that Best Bike Advice works well for, for example, a leg length difference or a curved spine.
ERIC VAN DEN BOGAARD
Bikefitter and Therapist
"In my career as a therapist and bike fitting specialist, I have seen many do-it-yourself bike fittings. These are generally far too limited because they don't take enough factors into account."
The online bike fitting from Best Bike Advice, on the other hand, is much more comprehensive and complete. This system takes important factors into account such as fitness, flexibility, back angle, and the dimensions of bicycle components.
SANNE VAN PAASSEN
Entrepreneurs coach and ex-prof
"During my professional career I had to get the most out of myself. The correct cycling position is an important part of this. I see many less experienced cyclists who do not have a proper cycling position. This is not only bad for the performance, but can also cause pains or injuries."
The Best Bike Advice bike fitting is a great tool to check and improve your cycling position.
