Cycle Source magazine is one of our favorite bike mags... real grassroots stuff, featuring daily-rider bikes built the little guy, usually the owner-rider, not just the big-name custom bike builders and the big corporations. We really like the down-to-earth attitude. Also, the design and photography is excellent.
Cycle Source got its start as a free publication in Pittsburgh, PA back in 1997. Eight years later, after expanding somewhat on the East Coast, editor Christopher Callen took it national.
If you like retro and vintage stuff, you'll like what you see in each issue of Cycle Source... bobbers, cafe racers, board trackers, etc. They've also got a great website and blog where they showcase cool bikes, parts, and cycle news, so you don't have to wait by the mailbox each month to see the cool stuff they feature. They are on Facebook, too.
You can sign-up for a subscription here at their website. You can also pick-up a copy at your local Barnes & Noble bookstore if you want to check it out before subscribing.
