Hotrock 20
Manufacturer Description
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.
