Giant ARX 20 2021

Why should lightweight performance be limited to adult bikes? This sleek little aluminium flyer is the lightest in its category, designed with stable geometry and 20-inch wheels that make it easy for young riders to get going. Most youth bikes are constructed with heavier frames and materials, but we designed the ARX to be lighter, quicker, and more fun for young riders. Fact is, smaller riders can benefit even more from a lighter bike.

It comes in three different wheel size choices for different heights, and has versatile tires that can handle rough roads, paths and even some dirt.

Weight The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
