Before the Quadangle there was the STR-1.

This dates back to the late 1970s when Stu Thomsen was SE Racing’s National #1 pro and the sport’s first superstar. His signature frame at the time was the Stu Thomsen Replica-1.

The STR-1 frame had a unique design with both of the double down tubes wrapping underneath the bottom bracket shell and continuing around the Looptail rear end all the way back to the seat tube.

Less than ten STR-1 bikes were produced, making them almost mythical and the most sought-after frames of all time in the vintage BMX world.
Fast forward over 40 years to today and SE is proud to bring you the third STR retro bike, the limited edition STR-24.

All of the unique features and radness of the original STR-1, but built for the cruiser class with 24in wheels. This bike comes with an authentic SE Racing/Stu Thomsen trading card personally signed by Stu.

Once again, “We Make It Happen.”
