Specialized Hotrock 20 Inch Boys bike

Season:2017

Brand:Specialized

Code:B4017-3309

Your little tike might love to ride, but given that they're still growing like a weed, the big kid trail shredder bike can probably wait a few years. That's why we made our Boy's 6-Speed Hotrock 20 with plenty of gear range to tackle the neighborhood hills, and enough to ride beginner's trails confidently. Of course, it also features a lightweight, yet durable, 20-inch A1 Premium aluminium 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 40mm 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 aluminium frame is built to stand up to years of tough riding.
  • SR Suntour suspension fork offers 40mm of coil-sprung travel that smooths out bumpy, rough terrain
