That does look kinda badass, but the rear tire looks like it would be a pain in the ass to change. Also, that's a lot of money: I think I'll be sticking with my ebike for now lol.
I have airless tires (Tannus) on me bicycle right now; I put them on last year, and I'll never have a bike without them again (I'm excited to see METLs!). Maybe these are similar?
