I like the rusty front rotor. Either he doesn't ride it or the front brakes don't work. If I had to guess I'd say it doesn't get ridden much. I can see why.
That thing gives me the willies! I must be vain by comparison, but any bike I ride has to look nice as well as be functional. This heap is a nightmare. Perhaps it was intended to be scary-looking. I dunno.
There was exactly that creation that came to a shop I worked at. He would show up every few months or so. It had a Chevy Geo Metro / Suzuki Swift with an auto tranny. Sorta looked bulky, but he was happy with it.
Nowadays I would like to try one with Mitsubishi Evo or similar powerplant.
Another fellow was building a trike with a Buick V6 powerplant. He took the whole engine with subframe out of a junkyard special and built a trike chassis around it. I never saw that one finished though.
