The Cub-Scout 20” is not just another kids bike: taking inspiration from our 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 our own children, we have 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; 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.
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, we took the time to test and develop our own or work with our partners to select the best kids-specific components we 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
Please Note: Due to severe delays in the bicycle supply chain, we have been forced to make some alterations to the specification of the component parts supplied with this bicycle. As a result the specification may differ from those shown in the images. Please refer to the specification table for accurate information.
Features:
- Kids Hardtail
- Hydroformed 6061 Triple-Butted Aluminium
