Biomechanical prediction for your perfect purchase
your perfect purchase
uBike advantage
Evaluate millions of options before you buy
If you are going to buy a bike, you must ensure that you choose the correct size.
Major brands estimate your bike size based on your height and inseam, but they also state that a biomechanical study is necessary to reliably select the correct frame size and components (cranks, stem, handlebar, seatpost…).
At UMANA, we carry out your pre-purchase biomechanical study using uBike technology, the only one capable of predicting your 3D pedaling on any bike on the market by analyzing millions of different positions and configurations. With uBike, you can determine the biomechanical suitability (%) of any bike for you and ensure a perfect purchase.
size selection
optimal picture
With uBike technology, we can decode your movement across more than 12 million pedaling positions for any bike, reliably and precisely identifying the optimal size for you in terms of comfort and performance.
Our technology includes an updated database with the geometry of more than 18,000 bikes on the market, and also allows the analysis of any custom geometry in the case of made-to-measure bicycles.
component selection
cranks, stem, handlebars, seat post/saddle
In addition, uBike technology allows us to calculate how your 3D pedaling movement changes when modifying any component of the bicycle. In this way, we can predict the benefits that each change provides for your comfort and performance.
We analyze more than 20 million different configurations and select the optimal dimensions for cranks, stem, spacers, handlebar, extensions, and seatpost/saddle.
pre-purchase report
% biomechanical suitability
Finally, we provide you with a report detailing your optimal size and components, indicating the % of biomechanical suitability in terms of comfort, power, and aerodynamics.
This report contains all the technical information necessary for you to place an order for your new bike and components with a store or manufacturer.
Why should we help you choose your size?
Why are we helping you?
Because sizing depends on the manufacturer and model
"In fact, your optimal size may differ depending on the brand and type."
Because you can't try on all sizes and components
“Even adjustable platforms are limited to testing only a few options.”
Because if you order the wrong size, you can't return it.
"And reselling your bike will almost always cause you to lose a large part of your investment."
Because with the wrong size you'll get injuries and discomfort
"which will increase over time and prevent you from enjoying and competing on the bike"
