Big On Loyalty
Till now all you have ever heard about the biker gangs or whatever you learned from us about what they do and how they rule comes down to a single most important thing; Loyalty. Biker gangs pay a bit too much attention to this aspect of their community.
The members of each biker gang especially those in giant gangs like Mongols and Hells Angels have to stay loyal to their gang till the day they die. Betrayal to the club of any sort can result in a member being seriously beaten and even worse sometimes.
