Blue Schwinn Motorized Cruiser Bicycle

Blue Schwinn cruiser bicycle with a motor attachment. Features a black seat and white-wall tires. Measurements are approximately 65 inches long and 40 inches high. I purchased this bike used. 2 stroke engine. It is way too large for me. I was told it works, but untested. Gas was empty. Uses 1 bottle 2 stroke oil with a certain amount of gas, but I know nothing about operating it. Just trying to get the amount I was out of.
