NS Eccentric 20 2025
This isn’t your average kid's bike. Developed personally by NS Bikes CEO and tested by his son, it has their own ‘pro kids’ geometry. You will see the aggressive stance that a kid takes on this bike and the confidence with which the young rider will tackle difficult terrain. The Eccentric 20 is fitted with a cockpit specially designed for smaller hands – the JUNIT ProTaper handlebar and complementary grips have reduced diameter. Short cranks with a narrow Q – Factor are critical for efficient pedalling. The fork is also an important component specially designed for kids – it’s lightweight, sensitive and has a 15mm thru-axle. Light, fast rolling tires are mounted on wide rims can be run at really low pressures, making the bike very comfortable and stable on bumpy terrain. The Eccentric 20 is the way to go for kids who are serious about mountain biking.
