I’m honestly mystified why not having Erg is a deal killer. For a couple years I used a Stages spin bike with resistance knob and power meter, never had a problem doing intervals. Did intervals outside by HR and then power+HR. Then Kickr with Erg for two years, with PowerMatch. And now a year of Kickr in resistance mode using my bike’s power meter. The Kickr is still a great trainer without using Erg.
