Supercross BMX in Japan

Supercross BMX has been designing race frames from Southern California since 1989. Japan is one of the strongest BMX nations in Asia — a serious racing scene, a deep freestyle culture, and riders who compete at the top of the sport internationally. Japanese riders know equipment, and they know the difference between marketing and engineering. That's exactly the customer we build for.

Built for Japanese Racing

Our frames are designed and tested for the top of the sport. The carbon frames are tested to three times the EN BMX safety requirement before they launch, and every geometry call still comes from the same designer it always has: our founder, Bill Ryan.

The Range

The Vision F1 and Vision F1x are our full-carbon race frames — UCI legal, built with Toray aerospace-grade fiber. The Vision F1x runs Toray M40x and M46x carbon, grades you will not find on other BMX race frames — fiber that comes from Japan's own Toray, the best carbon maker in the world. The ENVY BLK 2 carries the same carbon engineering into the 24" cruiser class.

The ENVY RS7 is our alloy race frame — 6069 triple-butted aluminum with race geometry that doesn't compromise because it's not carbon. Sizes run from Micro and Mini through Pro XXL.

We also build a full line of carbon forks, bars, stems, cranks, and components under Speedline Parts.

Ordering Direct From California

Direct orders through supercrossbmx.com ship to Japan from our Apple Valley, California building — orders placed before 2pm PST go out the same day. One thing to know up front: direct orders are billed in US dollars, and Japanese customs may collect import duties and consumption tax when the package arrives. Those charges are set by Japan, not by us. Buying from SBC Cycle skips the customs process entirely.

100% Designed in California — 37 Years and Counting

Supercross BMX was founded in 1989 by Bill Ryan, a former Technical Editor at BMX Plus Magazine who started building BMX frames at age 13 in Southern California. We've won USA BMX Bike of the Year eight times — the most of any frame brand in the award's history. Our frames have been raced at the Olympic level. Every frame is 100% designed in California.
