The Bike Sizing Process

After selecting a bike, the appropriate frame size and seat height are displayed.
3.
Now the bike can be adjusted to fit you, and you're ready for your first ride.

Smartfit Q4
The Smartfit Q4 is a true all-rounder—thanks to precise laser technology, we can accurately measure and adjust your body and your bike.

The Bike Fitting Process
1.
For a bike fitting, we measure not only you but also your bike. To do this, we place your bike on the Q4 and measure it using a laser.
2.
Then we can determine the seating position that’s perfectly tailored to you and your preferences (e.g., riding style).
3.
Now the bike is ergonomically adjusted for you, and you're ready for your next ride.
Smartfit Q5
Have you always wanted to see how you sit on your bike and where your riding position could be improved? With the Smartfit Q5, you get a comprehensive bike fitting, including video motion analysis.
