Nukeproof Cub-Scout 20 Race Youth Mountain Bike (2023 – Box

The Cub-Scout 20 Race features an alloy frame that takes agile and comfortable geometry from Nukeproof’s adult bike range, this gives your little trail shredder the ideal stepping stone into the world of mountain bike (MTB) riding. It is equipped with Manitou Machete Junit suspension forks, a BOX FOUR 8-Speed drivetrain with a wide-ranging 11-42T cassette and kids-specific Clarks hydraulic disc brakes. It also rolls upon 20″ Nukeproof Neutron Boost wheels wrapped in Tubeless Ready Maxxis Minion DHF 2.4″ tyres.

Engineered for Young Off-Road Trail Riders

The Cub-Scout 20 Race is not just another kids bike: taking inspiration from Nukeproof’s award-winning Scout adult hardtail range, the Cub-Scout 20 has been designed from the ground up as a proper mini-hardtail mountain bike. It has been designed to allow kids to learn the ropes of riding, inspire confidence on the trails and act as the perfect platform for progression. Developed and tested with the help of their own children, Nukeproof has created a class-leading lightweight kids bike range to inspire and nurture budding future World Cup or EWS winners.

The range of Cub-Scout Hardtails are available in 20”, 24” or 26” options. This means that there should be a bike to suit kids of all sizes from ages 5 and up. Each bike features a lightweight custom butted 6061 Alloy frameset with bang up to date long, low and slack kids specific geometry.

Kids Specific Components:

Proper fit and function of components are essential for kids bikes because adult components are not optimised for smaller people. To ensure that these bikes fit and function perfectly, Nukeproof took the time to test and develop their own or work with their partners to select the best kids-specific components they could find on the market.
