Hotrock 20
2020 Hotrock 20
Kids love to ride, but they also grow like weeds, which always leaves parents in a bit of a conundrum: Do you splurge on your child's bike when they’ll likely grow out of it in a few years? That's why we made our Hotrock 20—a well-priced and designed bike with plenty of gear range to tackle the neighborhood hills, and enough front-end travel to ride beginner's trails confidently.
The Hotrock also features a lightweight and tough 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.
