Most bike clubs with which I'm familiar are happy to have new potential members come out for a few rides before they join to see if it's something they want to do. The club I'm in currently had over 600 rides last year (i.e. just about every day and quite a few days with multiple rides), and that's not counting planned rides that were canceled due to weather or other issues. Check around for other clubs and also Meetup or similar groups in your area and see if there's a group that's a better match for you.
