Fun Flyer
Why should lightweight performance be limited to adult bikes? This sleek little aluminum 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. 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.

Key performance factors:
- Lightweight: High-quality ALUXX aluminum construction delivers exceptional frame performance with lightest weight in its category.
- Youth-specific features: 20-inch wheels and lightweight components offer better control and safe, ergonomic positioning and fit.
- Versatility: Versatile tires can be ridden on roads, gravel or dirt.
