Product Details
A lightweight, low-standover height frame with properly proportioned and easy-to-use controls makes the Hotrock perfect for a kid's first multi-speed bike. A 50mm of travel fork takes some bite out of the bumps.
20" A1 Premium Aluminum ATB frame with low standover height for care-free starts and stops with room for full-sized water bottle
40mm-travel SR Suntour suspension fork with lightweight alloy lowers and pre-load adjust takes the edge off bumps for more control
Lightweight 32-spoke alloy rims are durable and provide a stable platform for learning
Specialized Roller tires provide a knobby grip for dirt, but roll easily on pavement
Kid's Body Geometry saddle is durable and comfortable and fits young riders perfectly
Shimano Revo 6-speed twist shifters allow easy, safe gear changes without switching hand positions on the bars
