The first time we wrote about Robert Maddox was when he had a pulsejet bicycle for sale on eBay. It was a pretty interesting bit of work, a bit unusual, perhaps, but, everyone needs a hobby. It looks like Mr Maddox is very committed to this particular pastime because he keeps building bigger and better models and the latest is a dual jet version, still bicycle mounted but with a little extra style, and thrust, too.
For this build, he stacked two 60 pound thrust engines and even incorporated push button start, heck, it’s almost civilized. He’s still selling his pulsejets on eBay, too, so if you have the need for speed in an eccentric sort of way, he’s your man.
