Editing Unknown Bikers MC (section)

==Brooklyn origin and MC identity==
The club's later histories identify Williamsburg as its original base and describe that chapter as the mother chapter. A 2008 federal trademark application for “UNKNOWN BIKER'S, MC” identified the owner as Unknown Bikers MC, Inc. and described the mark as indicating membership in a motorcycle aficionado social club. The registration was issued in 2010 and cancelled in 2017 after the registrant did not file an acceptable Section 8 declaration; the cancellation does not establish that the club ceased to exist.<ref name="TSDR" />

The applicant claimed first use of the mark on June 1, 1974 and first use in commerce on November 1, 1995.<ref name="TSDR" /> Those are trademark assertions tied to the filing, not an independently verified founding chronology. Contemporary reporting separately documented a Williamsburg street club called the Unknown Bikers in 1978; whether that street club became the MC, contributed personnel to it, or was later incorporated into its history remains unresolved.<ref name="NYT">[https://www.nytimes.com/1978/03/06/archives/true-story-of-city-gang-life-no-glittery-west-side-story-true-story.html “True Story of City Gang Life: No Glittery ‘West Side Story’”], ''The New York Times'', March 6, 1978.</ref>
