FYI;Currently if you go to Shopgoodwill and search “bicycle” or “bike” you will find not one but four complete vintage bikes of varying ages and of good to excellent condition up for auction. I have never seen so many all at once, perhaps the passing of the recent lunar eclipse and blood moon?
Could one of these be what to borrow from U2 “[you] still haven’t found what I’m looking for?”

Cilo VHUS 979 (Black & Sliver)

De Rosa (Blue)

Urago (Red)

Bianchi Premio (?) (Red)

They won't fit me, but cheers and good luck.
