Are they abec or abec clone? Regular abec is. Bit bigger n beefier, ive got some abec clone pulleys that r pretty useless to me rn. But that looks like it might fit.
The covers might also be there so you can run some expensive ceramic bearings while still having some extra protection for them. The covers could make them pass as hub motors from a distance but they’re a tad too small to actually look like them to anyone who knows what to look for.
There is barely a day without some random person ask me if my push board is electric.
So I’m pretty sure we are a real few to know how it is supposed to actualy look like
To be fair, I think there are some builders on here that could be fooled by those covers too Hub motors aren’t exactly a popular option on here which is pretty reasonable since they hurt on any non perfect surface
