The Nakamura Glade 20" junior mountain bike is a great choice for an everyday junior mountain bike. The hardtail design, quality components and 6-speed drivetrain provide the rider with a versatile bike that is great for riding around the neighborhood while also performing well on recreational trails. This 20” bike is typically for kids between the age of 5 and 8, or 47” to 51” 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.
