So there are still 7-speed cassettes out there that (along with the appropriate spacers) will allow her to use the FX with the Kickr? That's promising, thanks!
Oooof...freewheels are a vintage affair but not something I would want on a modern bike unless I was trying to make more money off the end consumer. I have seen plenty of bottom end bikes from known brands and most of them these days have all gone cassette. With the ubiquity of free hubs and the ability to find cheap ones easily these days you would think a big brand like Trek would keep up with modern times...ah well.
You can find 7 speed cassettes (or they normally exist in non-covid times) just make sure the ratios are generally the same or smaller so you don't run out of chain.
