Taking inspiration from the award-winning Nukeproof Scout adult hardtail range, the Cub-Scout range of bikes have been designed from the ground-up as proper mini-hardtail mountain bikes. Nukeproof have designed a range of bikes to allow rippers from around 5 years old to learn the ropes of riding. Designed to inspire confidence on the trails and act as the perfect platform for progression, with optimised geometry and size specific components. Developed and tested with Nukeproof's own World Class test team (the team's own children), Nukeproof have created a class leading lightweight kids bike range to inspire and nurture the future generations of Downhill World Cup or Enduro World Series champions. 

The range of Cub-Scout Hardtails 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 tiny human optimised geometry.

Updated 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 their own or work with their partners to select the best kids-specific components they could find on the market.

Kids Specific Parts Include:

  • Nukeproof Urchin Saddle, Grips & Handlebars
  • Custom tuned forks for young rippers
  • Specific resized cranks
  • Kids specific brake levers
