Tires
To transport the bike, we’ve made it easy to remove and attach the front wheel. It is equipped with a quick-release system. The 20" lugged tyres with a 2.2 cross-section provide traction and lots of comfort. They help compensate for the lack of a suspension fork. The recommended tyre pressure is displayed on the tyre sidewall (between 2 and 3.5 bar). The 20" inner tube is compatible with cross-sections of 1.7 to 2.2. It has a Schrader valve.
