About this bike
With a lightweight aluminum frame, smooth front suspension, smaller 20-inch wheels and geometry that's designed specifically for young riders, the new STP can be a first step toward playful adventures in the dirt. Versatile enough to ride on streets, parks or trails, it offers kids a confident, controlled ride to help them build their skills. The 80mm suspension fork soaks up bumps, and powerful disc brakes help them negotiate steep descents. It also features kid-friendly components, including shorter reach brake levers and a comfortable saddle.
