Having done a recent poll, I can tell you a solid half the people here think wearing the same pants every day to work is acceptably cute, and a non-zero number think it's okay to do a moderate workout before work and not shower. With this information in mind, I question our ability to find your wife a good balance between "cute" and functional.
Anyway here are my vicarious-shopping nominations:
https://food52.com/shop/products/9553-rattan-bike-basket <- the right tone for gold and white
https://www.amazon.com/dp/B07VZWPSFG Coffee cup holder. Very practical. I actually should get this for my 13 year old who rides off with a coffee in one hand, phone in the other, and ... I'll just stop there, she's 13 and I've clearly failed as a parent.
Runners-up:
https://www.amazon.com/dp/B007JAWSD6 <- Nice lidhttps://www.amazon.com/dp/B0185N3LK4 <- Nice color
