Boy's 21-Speed Hotrock 24
Overview
Technical Specifications
Geometry
Little legs love to climb as big ones, which is why we made the Boy's 21-Speed Hotrock 24. It has wide gear range that puts any hill within reach, which means that they'll spend more time smiling and less time sulking on the side of the trail. Of course, it also features a lightweight, yet durable, A1 Premium Aluminum frame that's designed to take a hit while they find their legs on the pump track, while chatter and bumps are handled by the coil-sprung SR Suntour fork's 50mm of travel. Then there are a whole host of other components that are plenty tough enough to stand up to your little guy, so you can rest assured that you'll be spending more time riding with your kid and less time waiting in line at the repair counter. 
  • Tough, light, and durable, the A1 Premium Aluminum frame is built to stand up to years of tough riding.
  • SR Suntour suspension fork offers 50mm of coil-sprung travel that smooths out bumpy, rough terrain
