NS Bikes Eccentric 20

The smallest bike in the lineup is no ordinary kids' bike. It was personally designed by the CEO of NS Bikes and tested by his son, and features its own “Pro Kids” geometry. You’ll notice the aggressive stance a child takes on this bike and the confidence with which the young rider tackles challenging terrain.

The Eccentric 20 is equipped with a cockpit designed specifically for smaller hands—the Junit Protaper handlebars and matching grips have a reduced diameter. Short cranks with a narrow Q-factor are crucial for efficient pedaling. The fork is also a key component designed specifically for children—it’s lightweight, responsive, and features a 15mm thru-axle. Lightweight, fast-rolling tires are mounted on wide rims and can be ridden at very low pressure, making the bike very comfortable and stable on bumpy terrain. The Eccentric 20 is the right choice for kids who are serious about mountain biking.
