There's just something about people strapping jet engines to things they have no business being strapped to that brings a twinkle to our eyes, and Robert Maddox's pulsejet-powered bicycle is no exception. Maddox actually sells pulsejets on eBay ranging from fourteen to over a thousand pounds of thrust, and the fifty-pounder in this video is capable of moving his bicycle at a whopping 75MPH. Sure, it's loud, but at least it's more practical than that jet-powered Port-a-Potty. Video after the break.
