The Vitus Nucleus is the mountain bike you never forget. The one that got you hooked. It’s everything a mountain bike should be - comfortable, reliable and predictable. But above all, it’s fun.
The Nucleus is versatile enough to ride anywhere, but you’ll have the best time riding proper trails. It feels like a mountain bike should, inspiring confidence when riding off-road, over rough ground and when tackling trail obstacles. This is a real mountain bike and a proven performer, but don’t just take our word for it. The Nucleus is a multi award-winner that has been voted Hardtail of the Year four times in a row by MBR Magazine.
Riding your first mountain bike requires full trust in the equipment. As the trail twists and turns, rises and falls, you need to feel in complete control. The tried and tested geometry of the Nucleus has reassuring stability and agility that keeps your body relaxed and your smile wide. To match, the bike arrives equipped with high-quality, durable components. Hydraulic disc brakes are responsive no matter the conditions, the fork uses SR Suntour air-sprung suspension and the no-fuss Box Four drivetrain ensures the gear shifting is fast and light. But this bike won’t be left behind as your confidence grows. With the award-winning aluminium frame at its core, you will be able to fully customise and upgrade the setup to best suit your riding style and keep your mountain biking skills rolling forward.
Your first mountain bike should arm you with everything required to enjoy this sport. To set you on your way to unlocking the excitement of riding trails. The Nucleus is not off-the-shelf, it’s tailored specifically for the needs of a new mountain biker.
