This is the little, lightweight bike that I bought to replace my TW. It's a 1968 DKW model RT139. It's a 50cc two stroke, 3 speed, with the shifter at the left hand grip, like a Vespa. It's air/fan cooled, so it can crawl around all day, and not overheat. I put stiffer rear shocks on it along with a knobby on the rear, and a universal on the front, which I may put a knobby there also. One or two kick starting, and runs 28 to 30 mph flat out. I'm going to do some sprocket changes in order to give it a little more low end grunt. It only weighs around 150 pounds, and is just so light, and easy to maneuver. No turn signals, or horn to worry about. It has one of the little bells like you might find on a girls bike. No battery either. I love it.
