Nice bike for a child ready to learn how to shift gears.

Excellent!! A little more difficult for going up hills to start with until the child learns to keep speed a little higher for 18" wheels. The 18" wheels allows the child to ride at a faster pace with an adult and have more endurance to ride a longer distance.
