As with any bike, the right size is essential for a mountain bike. However, this does not only include the perfect dimensions of the tire to allow for optimal agility and control. Of far greater importance for beginners is the right frame height. This is selected depending on the body measurements and allows you to ride the bike comfortably and economically. Frames that are too small or too large do not contribute to well-being in the long run. Uncomfortable sitting positions can cause annoying back or neck pain and the power transmission to the pedals is no longer optimal. Therefore, use a frame size calculator to find out which height suits your body.
