The GT Siren 12" is a great way to get your youngster on a bicycle. GT did a wonderful job creating a simple and easy way to ease your child into the world of bicycles. The Siren has a durable and good-looking steel frame. A single speed drivetrain is as simple as possible so your youngster doesn't need to worry about shifting gears. Coaster brakes are very easy to use. GT paid attention to the details and added a chainguard and mud fender to help keep your child's clothes just a little cleaner.
