I see there are plenty of diamond frame cruisers within this thread.
I'll submit my recently acquired diamond frame cruiser, it replaced my cantilever frame cruiser also in this thread.
I believe it has a few items that might make the cruiser checklist. Single speed coaster brake rear hub, wide sprung saddle, retro quill stem, riser handlebars, finger groove Schwinn grips, and balloon-ish tires.
