Missed out on training wheels! We transitioned from a 12-inch Strider to a 14x when he was 3yrs old. On his 4th birthday we wrapped up the pedals as a gift and put them on the same day. He hopped on the bike and pedaled away . . .first try. No help from me. I feel like I kinda missed out on the thrill of the struggle. Ha! Putting the pedals on with one bolt was so easy the four- year-old could have almost done that by himself too!
