The X-Caliber and Roscoe, and my cheaper 2018 build of the Timberjack, and a lot of other bikes in that price bracket are full 141mm wide dedicated cup and cone hubs. The one on my bike does look a bit more serious than a hybrid hub, having bigger flanges and rubber dust seals. But definitely not the kind of thing you get with a thru axle. The most expensive version of the Roscoe, the one that somehow has a Microspline SLX cassette, might have something different.
Photos: my TJ, with trailer hitch. This version is convertible to thru axle with different Alternator but hasn’t been, yet, maybe someday… and, wife's hybrid
