Therefore, he had a large hand in all three major founding BMX magazine periodicals. He put on the first event that could be called a pro-class race anywhere in 1975 at Saddleback Park in Orange, California (US$200 purse). He was a founding member and President of the Professional Racing Organization (PRO), the first attempt to form a BMX professional racers guild. He both invented the modern BMX racing Cruiser and the Cruiser class to race them with. In September 1978, Breithaupt appeared at the famous Corona Raceway, in Corona, California, on a converted Emory beach cruiser. It had wheels and low rise handlebars from a motorcycle. That same year he convinced the National Bicycle Association (NBA) to start the Cruiser class. He also invented the inverted BMX racing bicycle stem (also known as a "gooseneck"). Unlike the standard "quill gooseneck" stem, BMX bicycles in need of a stem with a much tighter clamping force on the bars to eliminate movement forward or back. That could be caused by the more violent physical abuse racers put upon it like pulling with maximum force during racing and jumping their bicycles, these stems were four-point block clamps secured with Allen bolts, unlike the single point quill gooseneck that had a single "pinchbolt" configuration to clamp the bars. Most other stems of this type, like the standard gooseneck, raised the bottom level of the handlebars up, the inverted stem dropped them down. Breithaupt was heading to an NBA National in Las Vegas, Nevada in 1979 to race cruiser class a new division in BMX that at the time was made up of BMX bicycles (during this time most were converted Beach Cruisers with 26" diameter wheels, built for the larger rider
