I found a pair of these at a garage sale this summer. Both were dirty from sitting in a garge for many years, but in very good condition.
I havent done anything with the smaller of the two, yet(it will be my wife's bike). the 'bigger' one came apart last week. My daughter has called dibs on it(she wont fit it for at least another year). Here it is prior to tear-down
I repacked the bearings and cleaned it up. It didnt need any parts, other than grease. The original owner switched out the double for a triple. I'm sure my kid will like that when climbing the hill we live on.
I rode it before I tore into it, and it rides great, although too small for me. It seems to be a pretty well built bike. My daughter wants the rack back on along with some silver sks fenders.... we'll see
