Here is my 8 y/o taking his first turn as a solo rider on the 4 wheeler. He had only ridden as a passenger in the past so he was excited. Of course, later in the day, he managed to miss every one of the millions of trees in the yard, but crashed into the corner of the house! lol Both he and the 4 wheeler were fine, we kept it in 2nd geer so they couldn't go too fast.
DJ will be 11 in just a few days. It was his first time as well!
