2019 Hotrock 20

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 Hotrock 20 with plenty of gear range to tackle the neighborhood hills, and enough front-end travel to ride beginner's trails confidently.

Of course, it also features a lightweight and toug 20-inch A1 Premium Aluminum frame that's designed to take a hit while they find their legs on the pump track. Chatter and bumps, meanwhile, 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 ripper, 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.
