Flip up seat/hidden gas tank
I have wanted to ditch the peanut tank on my bike for a long time. I finally did! I made the new gas tank out of an aluminum water bottle. I attached it to the seat tube in between the wheel and the seat tube. The thing that I think is kind of cool is how I fill up now. I have a banana seat and there is a pin that holds the seat to the seat tube. To fill up, I remove the pin and raise the seat. This exposes the lid to the gas tank. Here are some pics. If you want to see more of my build it is under "Traditional Hot Rod Style" in the Rat Rods section.
