Here's my Tank Bikes. I have some other, but they're under restoration now.
1961 Schwinn Panther III, 1949 Schwinn Hollywood, The JC Higgins is no longer with us.
The only thing not old on this 53 Schwinn is the tank. I bought the tank from a Schwinn store about 10 years ago. Bought the horn unit from Memory lane classics over the internet, beeps fine, but I had to adjust the screw to get a lower tone. Everything else is from other old bikes. The twist grip shifter and pedals came from a 70's Montgomery ward's 3 speed. The chainguard is from an old schwinn from the old jacksonville shipyards. The crashrail seat is from a 64 Schwinn Starlet. That big sprocket with the red and green reflectors canme off a 2 dollar AMF bike frame from the thriftstore years ago. The springer is from a 59 Schwinn, and the struts are copper tubing from the plumbing store, homemade and painted silver. The wheels aren't schwinn, I couldn't find balloon tires for them, so these are standard 26 inch rims, the rear is old shimano 3 speed w coaster from the flea market, 3 bucks for a true and shiny wheel. I routed the shift cable through the tank to keep it clean and simple. The generator is ancient, but works with no rust. Still need a good headlamp. Up in ND, I spent most of the winter prepping and painting it. Now down her in Fl, it gets ridden 12 months out of the year.
