You would likely never see Hells Angels and Bandidos in the same bar or even in the same city! They are not at war with each other but they are most certainly RIVAL clubs and being in the other's territory is an act of hostility. Most certainly not my world but also begs the question: Can a Christian be a member of a 1%er Motorcycle Club? What is a Hells Angel or Bandido to do when they come to faith in Christ? The motorcycle club is their whole world and they are expected to put it above everything else. Their Club meetings are commonly called "Church" which tells you what sort of devotion is expected! Perhaps 1 Cor 7:24 is applicable but to what extent? I would say the music and entertainment world has similar demands or at least it very much has a hold upon you and is very hard to walk away from! Christ makes it quite clear: If any man will come after me, let him deny himself, and take up his cross, and follow me. (Mt 16:24).
A few Banditos ride through Lewiston once in a while. I've ridden past the HA clubhouse in Spokane. It's painted in HA colors but it looks abandoned. I didn't dawdle around to check it out.
There is a little interaction between CMA and 1%ers. Our state coordinator, Tom, is in touch with some HA guys. HA puts on community oriented events; I guess they are trying to keep themselves legitimate in the public eye and keep the heat off. They sometimes call Tom asking for volunteers for their more civic events. HA recognizes CMA is a ministry, not a club, therefore we're not invading their turf. We aren't out to cause trouble and we can be quite helpful at times. (Our motto, "Here if you need us.") Tom is very selective about who he asks to work with them. He reminds us, "You aren't going to lead one to the Lord... you're just there as a witness and a servant."
As I alluded to in an earlier post, 1%ers know CMA and they know CMAs code of conduct. If someone from CMA is in violation of their code or otherwise disrespecting their own colors, a 1%er has been known to pull their "cut" (vest with a patch) and inform a leader. Respect (or their concept of it) is part of the culture.
A guy I've known that came to Christ from that background quietly left and was never heard from in those circles. He never divulged what club he was part of. Only after he passed away did my pastor tell me he told him what club he was part of.
Yes, there would be a conflict of loyalty if one of them came to Christ. Typically, they do so when they become disillusioned by the life; when they put their heart and soul into it and it lets them down. IOW, if they become a believer, they were typically on the outs with the club already.
Then there's Warriors of the Cross... a Christian version of 1% er MCs. They're an interesting bunch. There is a chapter here in town and their president and I talk occasionally.
All that to say, Christians and MCs? It's complicated.
