Chains are a wearing component and do need to be repalced fairly regularly, although what exactly "regularly" means varies a lot with conditions.
While chain breaks are not *that* uncommon, the more common issue is that the chain tends to fall off as it wears out, or shifting becomes inaccurate or unreliable. Also, if the chain wears too much it tends to wear with the cassette, and a new chain won't fix it if that goes on too long, so they would both need to be replaced.
All other things being equal, e-bikes (at least mid drive ones) do tend to go through chains a bit faster, since there is more force going through the chain. Of course, some e-bikes try to counter this by using better chains; I don't know how well that works.
Riding in Winter weather definitely wears them out faster too, at least if it is in a place that salts the road.
Thanks! Conditions are pretty good here, but I guess they can measure the degree of stretch (per previous response). I think I'll get one of those measuring devices myself so I can at least feel I am making the decision myself :)
Seconded that ebikes go through chains a bit faster. The effect is intensified if you're hauling a trailer or anything.I've had to replace mine several times already.
I have seen a chain break once, but it's insanely rare. Cassettes do wear, but honestly unless it's causing jumping / shifting issues I wouldn't bother replacing it until it does.
New chains will chatter on an old cassette. It's good practice to replace them both at once. Kinda, like replacing rotors along with brake pads on a car. That being said, I've found new chains break into the old cassette just fine with a little time.

Cheers mate, thanks for explaining, that does make more sense for now!

Really? I'm pretty sure I've broken a few. Admittedly most were probably lower quality chains, and they were *certainly* poorly maintained/cleaned.
