Lightweight. Confident. Built to grow.
The Giant ARX 20 is a premium kids’ bike designed for children aged 5 to 8 who are ready to ride further, faster, and with more independence. With its lightweight aluminium frame, smooth-rolling 20" wheels, and child-specific components, it’s the perfect next step for young riders progressing from smaller bikes.
Unlike heavier steel-framed kids’ bikes, the ARX 20 uses Giant’s ALUXX-grade aluminium to keep weight low and handling responsive. The 20-inch wheels are paired with low-resistance tyres for easy rolling on pavement, park paths, and light trails. The 8-speed Shimano drivetrain introduces gear shifting, helping kids tackle hills and build cycling skills.
The short-reach brake levers, narrow Q-factor cranks, and light-action brakes are all sized for smaller hands and legs, helping young riders stay in control. The adjustable saddle height and low standover frame make it easy to grow with your child.
Available in four vibrant colourways—Phoenix Fire, Cobalt, Soap Suds, and Lime Punch—the ARX 20 combines performance with personality, making it a favourite for kids and parents alike.
