This 24-inch teen mountain bike features a robust steel frame and polyurethane foam for enhanced riding comfort. It offers balanced handling but lacks heart rate monitoring. The bike has a high-carbon steel frame and is designed for teens between 150 and 165 cm tall (4'9" to 5'4") with a maximum load capacity of 250 lbs. It features a reliable disc brake system.
