When I met my Mrs (although pretty much ex now) she had an ancient crappy Giant MTB, pretty much a BSO.
Sorted her out a decent Kona HT shortly after and she got into MTBing improving in skills and fitness very quickly.
A couple of years later I upgraded her to an Orange Sub 5, so we had his and hers Oranges!
She also got a semi-decent Trek road bike not long after, so although mine was carbon, hers was new.
Since then I’ve gone a bit crazy on the bike front, and to her 2, I have 9 bikes, ranging from a carbon 29er to a Pinarello Dogma 😮
I have no idea if she ever rides her bikes any more though 🙁
Cheers, Rich
