6 years old! Isn't that considered child endangerment?
That was my first thought considering that none of my grandchildren (all near that age) could do anything like that; but they couldn't dance and act like Shirley Temple at age 5 either, so everyone's different.
On the other hand, there are very many people in the world who don't think ANYONE should ride motorcycles, because it's too dangerous, and it's just a game, and the thousands killed each year "aren't worth the cost", so motorcycling should be banned. Could be headed that way, with our nanny state and all. So best not to go down that road.
He's ATGATT, he looks pretty coordinated, and kids that age bounce pretty well anyhow, at least mine did when they were swinging on grapevines over 20 foot gullies at that age ...
