forget the darn folding bag ...... you can always use a trash bag if really needed.....
The first is the low end current Dahon Boardwalk. Yes I do sell them as well.. they are ok ride MUCH nicer than the 20 year old red one you got there ( those are fun in stainless steel as a collectors item, otherwise not to smuch .... lots of things have happened in the last 20 years )
if you are on a budget look for a late model bike ... !!! USED
