Of all your bikes I really like the first one and the Sunbeam Opafiet '60', The Sunbeam is very tasteful and refined, a true metro commuter.
In a similar vein I'm restoring a 1958 J.C. Higgins lugged 3speed made by Steyr, with an otherwise stock 48cc, HT engine. But it's getting a smaller more efficient carburtor, a China made clone of the VM12 that the Yamahopper and PW 50 use.
