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. With its ALUXX aluminum frame and fork, ARX is the lightest bike in its category, which makes it more fun to ride. The frame features a lower center of gravity for added stability. 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. The frame is fitted with lightweight components that are sized specifically for young riders, including cranksets and cockpit components for various wheel options.
