This is my entry into the "Underrated Rat Buildoff" happening in the build challenge section. Please comment here. My entry is a 50 something girls Monark built Speed O King. All original as far as I can tell. I have a set of Carlisle lightning tires that were on the bike when I got it. As it sits right now: I confess that I had contemplated building a tall bike or a burrito from some old girls frames, but then I remembered this one tucked away in the corner.
