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. 

ith its aluxx aluminum frame and fork, arx is the lightest bike in its categorywhich makes it more fun to ride. The frame features a lower center of gravity for added stability.

  • WeightThe 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.
