Ivor was on a balance bike for a year or so. Then he rode a small borrowed pedal bike with training wheels for a couple of months. He talked every day about graduating to a proper motorcycle, like Travis Pastrana. We explained that he would have to learn to ride the pedal bike without training wheels first. “Take them off!” he yelled. He got the hang of that quick-smart once he knew it was the direct path to a Suzuki RM-Z 450 with a Honda CR500 engine swap. He’s currently 4 years old and rides a Woom Bike. They are really good little kid bikes. That’s all I know.
