A bike is great for children of any age, it encourages exercise and provides them the freedom to explore wherever their pedals may take them.

At Giant, we’ve designed our kids’ bikes to accompany as wide a size range as possible, while still making the bikes easy and fun to ride.

We’ve laid out the kids’ bike range below and the recommended sizing guide for their age, however, we cannot stress enough the importance of checking the bike fits correctly before letting them ride.

Your local Giant retailer will be able to assist with more accurate sizing advice as they can measure up in-store to provide the exact recommendation.

ARX 16” | Age 4-6 Years

Our range of ARX kids bikes are designed to be as light as possible – in fact, they are amongst the lightest in their class across the top brands, so they’re agile and fun to ride. The ARX 16 features a lightweight Aluxx-aluminium frame in a low stand-over design, with versatile tyres that can handle rough roads, paths and even some dirt.

ARX 20” | Age 6-9 Years

One size up from is the ARX 20” – aside from the bigger wheel size, there are a couple of changes to adapt the bike to make it better to ride. The gearing changes from a single speed into an 8-speed. This allows the bike to be ridden on steeper terrain, letting them tackle new challenges now they are getting older.

STP 20” | Age 6-9 Years

The smallest model of our youth mountain bike range. The STP 20 is perfect for introducing off-road riding to your children. It features a lightweight & durable aluminium frame designed specifically for 20-inch wheels, and a 60mm front suspension fork so you can learn how to conquer the bike trails.

ARX 24” | Age 9-11 Years

As the ARX moves up to the 24” size, the bike remains largely the same as the 20” version, however, some of the components are slightly modified to accompany the larger wheel size. They will still benefit from the lightweight frame and fork, 8-speed shifting, and low bottom bracket for a better centre of gravity.

STP 24” | Age 9-11 Years

This STP youth MTB features an 80mm front suspension fork, and a lightweight frame designed for 24-inch wheels. The wider Kenda Karma 2.2-inch tyres and powerful disc brakes help maintain maximum control as you push the pace with its 8-speed shifting. The STP 24 will test your off-road capabilities.

ARX 26” | Age 11+ Years

With its youth-specific design, the ARX 26” again has a slight modification to the components to accommodate the increase in wheel size. The short-reach handlebars are made to fit smaller hands, and a specially designed Giant Selle Royal Vivo Jr saddle helps keep young riders comfortable as they begin to tackle longer rides.

STP 26” | Age 11+ Years

The STP 26 is equipped with more advanced componentry so you can take your trail riding ability to the next level. Featuring a Giant Crest 100mm suspension fork with a remote lockout system, and high volume 26x2.25” tyres for maximum control. Designed with trail-inspired geometry that includes a longer top tube, tighter rear triangle and a slacker head angle for agile handling.

Kids Bike Helmets

Although bike helmets aren’t compulsory, we would always strongly advise any young riders to wear one while on the bike, as they are proven to increase safety. It’s important that kids cycling helmets cover three main points – lightweight, well fitted and secure.

To accompany Giant's kids bike range, the Hoot ARX Helmet and Path ARX kids’ helmets are designed to meet all the key points, while also having 7 colours to pick from. Starting at just £39.99, they are an essential accompaniment for any kid’s bike choice.

So, there we have it – while it’s impossible to be exact as not all kids have the same body proportions, the guides above should be sufficient to get the correct size bike. If you are still unsure, you can visit one of our retailers who will be more than happy to help guide you through the process of finding the ideal bike. You can find your nearest Giant retailer using our search function.
