Overview
About this bike
Designed for young riders looking to try out the dirt or pumptrack, this all-new shredder is built on a lightweight, super-strong aluminum frame with quick, responsive 20-inch wheels. Versatile - Built with a lightweight, strong and durable ALUXX-grade aluminum frameset, the bike cruises the pump tracks, trails, and streets with ease. Quick and Responsive - The frame geometry is designed for 20-inch wheels and a low saddle height, with a taller front end for a responsive, confident ride quality. Maximum Control - Powerful disc brakes and a 60mm suspension fork with a lockout option (available on select models) gives her safe and confidence-inspiring control.
