Can you get Alfine hubs with a thru-axle? (and disc brake, I've seen one with their roller brake and after doing a deep dive on that, passed on the bike despite low price used, the hills here would wear it out too quick).
The rear on their tri-folds isn't a thru axel, so it would work just fine. The same for a chain tensioner, like I used to have on my single speed to 3 speed conversion. And they come with disc brakes as well. I have discs on my 3 speed Shimano igh that I'm saving, and a 7 speed I have stored away. All these igh hubs have the option to get them with disc brakes.
