Don't try this at home kids!

I'll be impressed when they can change the back tire. I'll even let them practice on a bike with a single sided swingarm. But to complete the task, it's gotta be on a conventional swing-arm, brake intact, chain drive.

Makes me think of the story of Yermo and Duncan (and Leonard?) riding down from Hurricane Ridge, engines off for 17 miles. How far could one ride a stoppie down a slope like that?

Chain drive bike? Might as well also require that they use tire irons!

That could have gone so horribly wrong.
