  • Nukeproof Cub-Scout 20 Sport Bike (Altus) 2021

    This 20" kids bike has been engineered from the ground-up as a proper mini-mountain bike. It features a hard-wearing custom-butted and hydroformed alloy frameset, which makes it great for kids to learn the ropes of riding on. Nukeproof has also equipped this model with a range of kid's specific components to inspire confidence on the trails and act as the ideal platform for progression. Coming equipped with up-to-date long, low and slack kid's geometry, this ride is 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.

    Developed and tested with the help of Nukeproof's own children, Nukeproof has created a class-leading lightweight kids bike range to inspire and nurture budding future World Cup or EWS winners!

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

    Easy Assembly

    When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

    Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

    • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
    • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
    • All bikes for worldwide delivery outside the EU will be delivered in small boxes.
