Yes, there's a club called the Arizona Sunriders. https://arizonasunriders.ridetrails.org. They have meetings the 2nd Friday of the month (November-March). The general membership meeting is held at 235 E.Ironwood St, Quartzsite at 10 am (information taken from the Quartzsite "Desert Messenger."
I don't think so. There's all sorts of other clubs and gatherings, though. From miniature airplane to metal detecting, gold seeking to jewelry making, art classes to history buffs and more. Maybe post on 'Quartzsite Chatter' or 'Quartzsite' and ask. Good Luck!
