Whether the bike is an old Schwinn Crate or a pimped out low rider, the 20 inch bike is a classic. Depending on the child's size, the 20 inch bike will fit the average 6 year old and up. Most bike companies will introduce a rear hand brake to compliment the rear coaster brake. Some bike manufactures will have models with a lower top tube to accommodate a younger child. Many frames are made from aluminum which reduces the weight of the bike and improves the riding quality.
