The Diamondback Pines (26") junior mountain bike is designed specifically as a tweener bike for riders who won't quite fit a 27.5" wheeled mountain bike. The lightweight hardtail design, quality Shimano® components and 7 speed drivetrain provide the young, or smaller rider with a versatile bike that is great for all around riding on a variety of trails. This 26” bike is typically for young riders aged from 10 and over, or 55” to 62” 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.
