Product Information

Little legs love to climb as big ones, which is why Specialized have made the Boy's 21-Speed Hotrock 24. It has a wide gear range that puts any hill within reach, meaning 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.
