Overview

About this bike

From the driveway to the bike park, the new STP 20 helps young riders build their skills and make the transition from wobbly laps around the block to fun trails and off-road terrain. 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. Versatility For Dirt or street - Lightweight, strong, and durable aluminum frameset is designed to go from street riding to bike parks or trails. Kid-friendly design - Frame geometry is designed specifically for young riders with 20-inch wheels, a low saddle height, and a taller front end for a stable ride quality. Maximum control - Powerful disc brakes and a plush suspension fork with a lockout option puts maximum control in the rider's hands.
