    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 aluminium 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 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 60mm suspension fork* soaks up bumps, and powerful disc brakes help them negotiate steep descents. It also features kid-friendly components such as shorter reach brake levers and a comfortable saddle. (*on select models)

    • Weight The 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.
