Hotrock

Designed for Fun

Lifetime of Riding

Freedom

Hotrock

Designed for Fun

Grown-up bike technology and quality dialed for big kids looking to attack the trails.

Lifetime of Riding

If it's time to stop pushing and start pedaling, the Hotrock makes the transition fun, easy, and sets them up for a lifetime of riding.

Freedom

Perfect for zipping around the campground or the out-n-back ride on the bike path.

Hotrock

The little ones who ride a Hotrock—and the parents who buy them—want “big kid” quality and technology in a “little kid” package.
