This thing looks all sorts of insane — but it’s real. It’s a one-of-a-kind twin pulsejet Harley Davidson motorcycle built as a custom job for a customer who never paid for it. It was briefly up for sale on eBay, but it looks like we all missed out.
This nitrous backfire may have only lasted a few tenths of a second, but we imagine that was far too long for the unfortunate Harley owner shown in this video.
