It may be an Atlas, but at least it is not the current Atlas industrial bike. The site is here, click on "Cruiser" then "Atlas" to see a photo of their current bike: http://www.sunbicycles.com/sun/index.html
Note that on the current bike, the lower bar intersects the upper bar, and doesn't go all the way back to the seat tube.

Now, a question here. On the front fork, it doesn't have the little lawyer-tab thingies. Instead, the axle holes on the fork are not cut the full width, so you can't just lift the axle out of the fork. I assume you just spring the fork out to the sides, however far that takes, to get the axle out? Sort of a pain. I'm thinking I'd be better off to file those slots so I could just slide the axle out next time?
