STP 24

2021

Designed for young riders looking to hit the dirt, trail or bike park, this all-new, all-around shredder is built on a lightweight, super-strong aluminum frame and quick, responsive 24-inch wheels.

With its quickness, durability and lightweight feel, this reengineered STP helps young riders get rolling on trails, pump tracks or bike park terrain. Made with a gusset-free ALUXX aluminum frame and 24-inch wheels, it has a low saddle height and taller front end so they can rail corners and stick their landings. Disc brakes help them stop on a dime, and this series is available with either a suspension fork or a rigid fork to suit different riding styles and terrain.

Quick and responsive

Maximum control

Powerful disc brakes and plush suspension fork with a lockout (available on some models) option puts maximum control in the rider’s hands. Grippy, high-volume 2.6” tires are ideal for multi-surface riding on streets, trails or bike parks.

  • 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.
