The award-winning FirstBIKE FAT balance bike features inflatable tires suitable for unpaved terrain (sand, gravel, and snow), and an integrated hand-controlled rear drum brake with SafetyStop. The high-tech, injection-molded composite weatherproof frame 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.
