NS Bikes Eccentric 20 Youth Trail - Dark Chrome

The smallest bike in our range – not an ordinary children's bike

The Eccentric 20 is not an average children's bike. It was personally developed by our CEO and tested by his son. The bike features our own "Pro Kids" geometry. At first glance, you can see the aggressive stance a child takes on this bike and the confidence with which young riders tackle difficult terrain.

The Eccentric 20 is equipped with a cockpit specially designed for smaller hands – the JUNIT ProTaper handlebar and matching grips have a reduced diameter. Short cranks with a narrow Q-factor are crucial for efficient pedaling. The fork is also an important component specially developed for children – it is lightweight, sensitive, and equipped with a 15 mm thru-axle.

Light, fast-rolling tires are mounted on wide rims and can be ridden with very low tire pressure, making the bike particularly comfortable and stable on rough terrain. The Eccentric 20 is the best choice for children who are serious about mountain biking.
