2021 Nukeproof Cub-Scout 20 Box 4 Race Kids Bike

It features a hard-wearing custom-butted and hydroformed alloy frameset, which makes it perfect 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.

Admittedly my website is more geared towards adult sized bikes, as these tend to be the models which are the most popular, and offer you the most savings. Also, often the only reduced kids bikes I see are the cheap and cheerful ones, and I don't want to promote rubbish bikes to my visitors! However if and when I find any discounted kids bikes, then I include them in my kids section. If you can't find a suitable bike there, why not see my Road Bikes and Mountain bikes sections, where you can check out the smaller models which may well fit younger legs.
