Ooph... I didn't even consider that! First because I didn't really want to give up on the CowBoy (I did have few problems with it after a while but manage to somehow gradually get it back, kinda, but honestly as I said, not worth it) but mostly because it's damn heavy. It's perfectly fine for an e-bike but even without the battery it's a bit of a tank.
So no, I bought an entry level single speed where you can flip the back wheel as fixed gear or just free wheel. I wasn't sure I would stick to Fixie... but it's been months now and I don't remember ever considered going back.
There was a sweet spot where there was. My road bike frame is from the 80s or 90s. It was built for downtube shifting, but now it has brifters. It has mixed shimano group parts from a maybe 2 decade span of time. Quill adapter to use modern handlebars made over the last 2 decades. Pretty standardized 8 speed stuff.
