We fit bikes to cyclists of all abilities. For more than 15 years
Every cyclist is unique, so they need to set up their bike individually. And that's our job. To fine-tune your riding position so you feel as comfortable on your bike as if it was made just for you.
3D biomechanical motion analysis + saddle pressure point analysis + unprecedented component knowledge = the best fit

JAN FALGE
Probably nobody in the Czech Republic has been involved in bike fitting as long and as honestly as he has. He combines education, racing career, experience and passion for the field. For many cyclists in the Czech Republic, fitting is rightfully associated first and foremost with the name Honza Falge.
VÍT ŘEHÁK
Successful MTB racer, skilled service technician and fitter with detailed knowledge of bike construction, components and their compatibility. In KOA he has been doing bike fitting since 2019.
Why is bike fitting for you? Because you ride a bike.
And it doesn't matter if it's for pleasure or for performance. The right position on the bike to suit your ambitions and needs can make you a completely different cyclist.
Comfort
You'll be surprised how comfortable you'll feel on the bike. Yes, even on the saddle.
Injury prevention
Thanks to a properly adjusted bike, you will not overload any parts of your body unnecessarily.
Better machine handling
The bike becomes more controllable and you gain more confidence and stability. You'll enjoy riding more and your bike will be safer.
Higher efficiency
And on top of that, you'll transfer power to the pedal better, so you'll get a few watts of gain with almost no work.

Sizing or When you want to be sure of your size

Choosing a new bike should always start with sizing. And not just when you're having a custom racquet built, but also when you're choosing a machine „from a catalog“. Thanks to the precise measurements of an experienced fitter, you will never again be sold a smaller or larger bike that doesn't fit you. You will know exactly what model you need in what size.
Our motto is clear: Enjoy the journey. Because when you train on a well-set bike, you train with enjoyment.
Technology
Velogicfit
Advanced technology developed by biomechanics and engineers based on expert knowledge of anatomy, ergonomics and aerodynamics. It allows KOA fitters to scan the cyclist from both the left and right sides simultaneously, so the final fit is super precise. But most importantly, you as a cyclist can also see on the big screen in real time how even a small change has affected your riding position. Getting your bike set up on Velogicfit technology is an experience that will make you feel like a pro, at least for a while. And that's what you really want to experience.

gebioMized
This "blanket", which senses the distribution of pressure points on the saddle, will help an experienced fitter to choose the right saddle, but most importantly it will confirm that the position you have just set is really the best possible one.

A properly designed and set-up cockpit in a time trial special today determines whether you can sell the incredible hours you've invested in training in a race.

Variants of bike fittingu
Measurements and settings on your bike
- We measure and adjust contact points directly on your bike using 3D biomechanical motion analysis.
- As part of the fitting process, we also measure the pressure points on the saddle using gebioMized technology so we are able to recommend the most suitable saddle model for you.
- As part of the fitting, we also check and adjust the position of the trunks on the trunks if necessary.
- You will receive the measurement results from us in a clear PDF KOA Bikefit Report.
- The price also includes the possibility of a follow-up consultation and adjustments (if necessary) within 14 days of the measurement itself.
5.000 CZK
Measuring before buying a bike (Sizing)
- Choose this option if you want to buy or have a new bike built. First, we'll discuss your idea of a new bike (how often, at what level and on what terrain you want to ride, and choose a bike category).
- Next comes the measurement on the positioning wheel (Retül Müve), or sizing. During the sizing, we will find out your optimal position, according to which we will select the appropriate frame geometry and components.
3.000 CZK
Pre-purchase measurement (Sizing) + Fitting
- Choose this option if you want to buy or have a new bike built. First, we'll discuss your idea of a new bike (how often, at what level and on what terrain you want to ride, and choose a bike category).
- Next comes the measurement on the positioning wheel (Retül Müve), or sizing. During the sizing, we will find out your optimal position, according to which we will select the appropriate frame geometry and components.
- Once the new bike is available, the bike fitting itself follows directly on your new bike.
- As part of the fitting process, we also measure the pressure points on the saddle using gebioMized technology so we are able to recommend the most suitable saddle model for you.
- As part of the fitting, we also check and adjust the position of the trunks on the trunks if necessary.
- You will receive the measurement results from us in a clear PDF version of the KOA Bikefit Report.
- The price also includes the possibility of a follow-up consultation and adjustments (if necessary) within 14 days of the measurement itself.
