Just get out there and ride! Don't need lycra or special shoes. A helmet is optional...your choice.
I am just a guy with a love of the bicycle and a firm believer it is a viable form of transportation. The bicycle is an amazing invention. It allows a small human to transport a large load over long distances easily. It is THE MOST ENERGY EFFICIENT FORM OF TRANSPORTATION...PERIOD!!!
It is a Rolling Rock beer promo bike. As best can be determined from the late 90's. It was apparently made by Dahon, there is a single sticker on the downtube that says not to ride it until it has been properly serviced by a Dahon service agent. It has very low end equipment on it, but that doesn't really matter it is slated for conversion to a folding city bike with IGH, coaster brake, fenders and lights.
Anybody know their Dahon models well enough to know which one this is based on?
