The award-winning FirstBIKE Cross balance bike features air tires ideal for off-road conditions (grass, gravel, or loose dirt surfaces), an integrated hand-controlled rear drum brake with SafetyStop, and a high-tech, injection-molded composite weatherproof frame that doesn’t scratch, splinter, swell, or rust like wood or metal. The hand-controlled, rear drum SafetyStop™ brake ensures very gentle and gradual braking; and the braking power can be adjusted.
