The Diamondback Revolve 1.0 (12") junior hybrid bike is an excellent choice for young cyclists. The lightweight aluminum frame with kid-specific geometry, combined with alloy components and a single-speed drivetrain, provides comfortable ergonomics. The wide tires with medium tread make for a plush ride and improved grip in any condition. And the rear coaster brake and training wheels will help your kid bike with confidence, perfect for riding paths with family and friends on sunny days. This 12” bike is typically for kids between the age of 2 and 4, or 32” to 39” tall. When purchasing a bicycle for your kid, it is important to choose the right size. Your choice should be made considering the size fit, not only the age of your child. In-store sales assistants will help you to make the right choice.
