My nephew got his first 2 wheeler w/ training wheels when he was 2 1/2. He had the training wheels taken off when he was 3. He can ride his bike with no problems. He likes to get speed and take his feet off the peddles and place then on the bar and stand as he rides. He is now 4 and asking for a skateboard. My daughter is 4 and still has problem with the 2 wheeler w/ training wheels. Each kid is completely different. You will find out pretty quickly if he is ready.
