The Nucleus 26 – based on our award-winning Nucleus range, this mountain bike features progressive geometry and simple, confidence-inspiring components.
Our Nucleus 26 mountain bike is specifically designed with progressive geometry and easy-to-master components to make your little one's first forays into trail riding, action-packed and enjoyable. Coming complete with 100mm-travel Spinner Air suspension forks, easy to use 1x9 Shimano Altus gearing and super grippy Schwalbe Nobby Nic tyres.
Vitus have spec'd the Nucleus 26 with a set of Spinner 300 forks. A light weight alloy fork with 100mm of travel supported by an air cartridge. This allows you to set the forks to the child's weight allowing them to get maximum travel out of the fork. Traditional spring forks can be tough for kids to use and they can struggle to use all the travel. The Spinner 300 forks also have rebound adjustment along with a full lock out switch allowing you to dial in the forks to suit your child's riding ability.
The Shimano Altus/Sunrace drivetrain is the perfect combination of performance and durability, with the Altus 9 speed rear derailleur, all powered by Altus thumb shifters. The 1x9 speed system is driven by a set of Sunrace cranks, with their light weight alloy arms and a 30t narrow wide chainring to reduce weight and maintain strength. All of these will ensure the classic Shimano reliable shifting and performance but keep you supported when battling the mountains.
Tektro M290 hydraulic disc brakes with a 160mm 6 bolt lock rotor on the front and rear, offering high stopping power for tracks that you might not normally hit up.
Rest assured that each Vitus bike is fully built, tested and tuned by our exclusive retail partners team of qualified bike mechanics to ensure your bike arrives in perfect condition.
