I want a jet powered beach cruiser

I just found my dream bike!
Check out Robert Maddox's pulse-jet motors for bicycles.... Only 13 pounds, and puts out 500 pounds of thrust. Strap it to the bike of your choice (preferably well built), and let 'er rip! Amaze your buddies on the next hillclimb! Merge safely with freeway traffic... (not really kids, don't try this at home... etc)
He sells them on eBay for $810...

I will if you will... but you first ;)
