For sale is a working Dorcy speedometer. It was on a bike with 26 inch diameter tires. There are NO instructions.
However it's easy to install. You place the drive wheel on the right side of your front wheel. And you mount the gauge to the handlebar stem.
Note there is a small crack in the plastic cable housing at the upper portion where it transitions to the metal end. However this area is covered by the sliding spring like metal piece. I only mention this in case you might want to place some tape over it so that moisture does not enter into the cable housing. First $30 cash. I'm located near Greenwood High School.
