ACS BMX FAQ
Who or what is ACS BMX?
ACS stands for American Cycle Systems and is one of the absolute foundational brands in BMX. It was founded over 50 years ago by aerospace engineers Charles Stephens and Robert Hanson – even before today's BMX disciplines existed. Originally started as a domestic manufacturer in the US, they developed and produced some of the first high-end BMX components.
What was ACS known for in the early days?
In the 1970s, ACS alloy hubs dominated the BMX scene. Their durable composite wheels (ACS Mags), often known as "Z-Rims", were also extremely popular and defined the look of many BMX bikes of that era.
What impact did ACS have on the 80s Freestyle Boom?
When BMX Freestyle exploded in the 1980s, ACS was at the forefront, developing specialty components that the pros urgently needed. ACS became a pioneer for freestyle-specific parts.
What were the most iconic freestyle products from ACS?
Some of the most legendary and influential freestyle parts from ACS include:
- ACS Rotor: The first commercially available rotor (detangler) that enabled infinite barspins – an absolute revolution.
- ACS RL Hub: A special hub, likely developed with or named after freestyle icon R.L. Osborn, designed to meet the demands of the sport.
- ACS 100psi Tires (R.L. Edge): One of the first tires capable of handling the extremely high pressure of 100 PSI, providing low rolling resistance, especially crucial in flatland.
- ACS BOA Brakes: An innovative front brake with a unique design.
- ACS Z-Rims (Mags): The durable composite wheels remained very popular in freestyle as well.
Does ACS BMX still exist today and what do they produce?
Yes, the ACS brand still exists today. Over the years, the company evolved from a purely American manufacturer into an international supplier with manufacturing facilities in several Southeast Asian countries. They still sell many of the BMX and Single Speed components that established their reputation as pioneers, particularly high-quality freewheels (like ACS Crossfire) and other classic parts.
Can you still buy the old ACS classics?
Original parts from the 70s and 80s are now coveted collector's items (NOS - New Old Stock or used). However, there are modern products inspired by classics, such as the Odyssey Frequency G tire as an homage to the R.L. Edge.
