I'm a fairly competent mechanic but can't figure out how I would go about getting these bearings out. It almost looks like the inside of the hub shells(?) are threaded but I've never seen bearings with a threaded outside. I also don't see how I would remove the spindle to tap the bearings out. Am I missing something here?

I’ve seen a design where there were hex key interfaces inside of the endcaps but never in an axle. But one picture looks like there may be one inside this one.
Often you have to tap the axle out with a mallet which would push one bearing out with it, leaving the other in. You’d then tap the other one out from the side that you now have access through.
The bearings are ceartainly not threaded. There is no way you could thread them into something really.
Yes those are simply standard radial cartridge bearings, ” It almost looks like the inside of the hub shells” Thats not threaded rather, its a just a stepping bear the bearing matting surface.
 “I also don’t see how I would remove the spindle to tap the bearings out.

Put a nut over the threaded part of the axle but leave room between the nut and the bearing, if you hit directly on the axle you can damage it easily and flange the outer edges of it
These look no different than the dozens of trispokes i have replace bearing on in the past. Similar to Coreama and Fast forward wheels
