The fact that a freehub, which I've always found to be a bomb-proof thing that "just works", is considered a consumable on an e-bike might suggest that higher standards are required for thing that have to deal with power from motors than things that just have to deal with my weedy legs.
There are consumable things that you know will
definitely wear out: brake blocks/pads, chains, chainrings, cassettes, cables, jockey wheels, etc... And there are things that, while obviously not immortal, you expect to keep going for a couple of years at least - and with regular maintenance and regreasing of loose bearings/ replacement of sealed bearings - carry on indefinitely. From my experience on ordinary pushbikes I put freehubs into the latter category
The fact that
Ribble have put freehubs in the former category of consumable things says to me that Ribble have deliberately under-specified the freehub and used one that's not fit for the rigours of dealing with motor power. They are knowingly selling dud equipment and covering their arses with a dubious small print claim that freehubs are consumable. Shysters.
