The title of this volume Outlaw Bikers as Organized Crime reluctantly combines two highly contested concepts into a statement that is perhaps disputed even more. Who and what do we refer to when we talk about ‘outlaw bikers’ and ‘outlaw biker clubs’? What is meant by ‘organized crime’? And, how – if at all – are these two concepts related? All the chapters in this volume deal with these questions some way or the other, either explicitly or implicitly, each providing its own answers based on the data and methods at hand. This volume presents cutting-edge research on outlaw bikers and outlaw biker clubs from countries all over the globe and reflects the different ways that academic researchers have approached the outlaw biker phenomenon from the theoretical and methodological vantage point of organized crime research.
