The Metric 24 is for kids ready to go farther.

The Metric 24 is a 24-inch bike designed for kids ready to adventure beyond the neighborhood. This durable aluminum bike rolls fast and is lightweight to easily lift onto a bike rack. Just like our adult-size flat bar road bikes, the Metric 24 features flat bars, signature Diamondback design, and quality Shimano parts. Soft rubber handlebar grips and a Diamondback Jr. Padded Road bike seat keep young riders comfortable on longer rides, while smooth-rolling 24x1.75-inch tires let them keep up with their crew. The Metric 24 does double-duty as a ride to school and as a weekend getaway machine to cruise the bike path or explore around town with friends or family.
