My son had a wee rider at 2 from Walmart didn't ride it much at all. At 2.5 we got a Strider off the the internet at 3 he was riding a two wheeler with no training wheels. I highly recommend this, but you don't necessarily need a special bike. A 10 inch/12 inch bike with pedals removed and a lower seat will give you the same effect. Good luck
