The first rider-owned company, SE Racing, is a major force in the BMX industry.

In 1977, Scot Breithaupt founded Scot Enterprises, and soon after, SE Racing was born. The next year SE produced its first bike, the JU-6. Two years later, Perry Kramer, the top rider on the SE team, insisted that a gusset be welded to the top tube junction for strength. Once the frame redesign was completed, it became Perry’s signature bike, the “PK Ripper”. With over 45 years of production, the PK Ripper is not only the longest running bike in the sport, but it’s also the most legendary BMX bike of all time.
