Compatible bikes

I have been using my Kickr Core with my road with great success for 3 years. I now need to get a bike for my wife who has a disability but is keen to get fit. She is not currently able to cycle outside. Rather than buying a indoor cycle trainer, I thought utilising my Kickr Core and a subscription to Wahoo X would be a better option.

She would need a proper ladies bike, fairly upright with a comfortable saddle and high, quite close handlebars.

I would like to know if anyone has experience of this and could recommend any suitable bikes that would be compatible with the Kickr.

Thank you.
