Hey, Almost Trick, our fatties have the same rubber. I replaced the truck inner tubes with Surly 3". Lightened the wheels up just a teeny bit. The old tires and tubes went to Working Bikes Co-Operative, so my garage doesn't smell like Harbor Freight anymore. What did you use for a red rim strip?
Never rode a kickback, either. The Monark has a shifter that looks like a brake lever. Imagine not having ridden a coaster brake bike for over forty years and then taking that 75 lb tank down a steep hill. Grabbing a handful of shift lever will not slow you down in the slightest. The new Sram 2 speed is supposed to be pretty nice, too.
As far as the yellow fenders go, they were what was on the shelf and I bought 'em. The John Deere color scheme worked out well.
A few more. 1954 Robin Hood. 2 speed fixed gear Bendix hub
The Mighty Dunelt. 1964, 2 speed fixed AW, 26" mtb rims. A hoot.
