Nukeproof Cub-Scout 20 Sport

Nukeproof Cub-Scout 20 Sport

Nukeproof's all new Cub-Scout 20” Sport is not just another kids bike: taking inspiration from their award-winning Scout adult hardtail range, the Cub-Scout 20” has been designed from the ground-up as a proper mini-mountain bike.

The Cub Scout 20 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 have created a class leading lightweight kids bike range to inspire and nurture budding future World Cup or EWS winners!

The new range of Cub-Scout bikes are available in 20”, 24” or 26” options; meaning that there should be a bike to suit kids of all sizes from aged 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 is 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 our own or work with their partners to select the best kids-specific components we could find on the market. 

Kid Specific parts include:

Cub-Scout 20” Frame 
Nukeproof 20”+ Rigid fork
Tektro Hydraulic Disc Brakes with short stroke levers for smaller hands
Nukeproof Neutron Jr Saddle 
Nukeproof Neutron Jr Handlebar (20” – 600mm/24” – 640mm/26” – 700mm)
Nukeproof Neutron Jr Grips
127mm Samox Square Taper Crank
WTB STi 30 TCS Rims (Tubeless Ready)
Large Volume 2.6” Vee Rubber Tyres to ensure grip and a smooth ride
