Portions of that are ingenious IMO. The entire front portion is apparently affixed to fork and handlebars and swivels with the steering which is why his top has a weird looking shape. Cut-out in front for room to swivel inside, on the top sides so it doesn't scrape his shoulder when it sways; there is a logic to it.
His tailbox isn't much different from what I'd make.

I don't understand the training wheels though.
