Specialized 21 Riprock 24


Dirt, street, trails—the Riprock 24 doesn't fit neatly into any one box. It's purpose-built for fun, no matter how your little tike decides to ride it.



With a pair of our ultra-wide, 2.8-inch tires and comfortable, confident geometry, smiles are going to be guaranteed. That's because the big tires and 24-inch wheels provide heaps of traction, control, and confidence over any terrain, while a bump-eating, coil-sprung suspension fork will make quick work of absorbing any rough stuff.

Throw in a set of powerful, low maintenance mechanical disc brakes and a low standover that makes getting the perfect fit a total breeze, and your little munchkin has a bike that's going to make every kid in the neighborhood want to rip and rock around the neighborhood till the sun goes down.

  • The A1 premium aluminum frame is lightweight and built to withstand the tough use by kids, while the geometry features an ultra-low standover that makes it easy for your little ones to fit on and grow with the bike.
  • Custom SR Suntour XCT fork features a sturdy construction and a coil spring that delivers 70mm of bump absorbing travel.
  • The 2.8-inch Big Roller tires not only ensure exceptional traction, but also offer greater ride quality, stability, and loads of fun.
