Gremium Motorcycle Club is a German outlaw motorcycle club. Gremium claims to be the largest German motorcycle club since the patchover of the also formerly Mannheim-based German chapters of the Bones MC to the Hells Angels MC in 1999, with 73 full chapters in Germany, 71 chapters in other European countries, several associate chapters in Germany, and a prospect chapter opened by German expatriates in Pattaya, Thailand in 2007.
