I had both my twins riding at bout 5 years old without training wheels. First started with the training wheels so low that sometimes the bike would stop due to uneven surface which would lift the rear tire. Then we moved them up a 1/4" at a time, and told them to ride without making the training wheels touch and make noise. After a couple weeks , I realized that the training wheels were up 3 to 4 inches above where they needed to be, so I pulled them, and they have been riding ever since without them.
