...the number one E-bike has a "spoke protector" fitted behind the rear cassette (designed to stop any derailleur override depositing the chain into the bottom of the spokes). I understand that our 'merkin cousins call it a Dork Disk. Anyway, from fairly early in ownership, it has been cracking up, and looks pretty unsightly (though I suspect it would probably just about function). I could probably remove it by nibbling it away, but I have suffered in the past (other bikes admittedly) with the chain overriding the top cog, so I'd prefer to replace it. That requires removal of the rear cassette, involving the use of a chain-whip and a cassette remover.......... ....so, having found both on eBay for £2.49, I've ordered them. Chinese, of course. This is going to go well, isn't it......

Just cut the bugger off and make sure your gears are set up right.
Sheesh !

Aye fair enough, understood, but y'know, if your derailleur does catch, that wee bit plastic is going to make hee haw difference. Better off greasing your cables, very satisfying and can be spun out over several evenings. 😬

I've removed these from a number of bikes over the years. Usually because they combine with flexing spokes to make an irritating noise.
Not sure they would have stopped a chain over riding top cog and jamming, more about keeping an ill adjusted derailleur out of the spokes.

Most keen mountain bikers remove anything that can shatter and puncture you when it ( inevitably from time to time ) all goes mammaries up. All reflectors etc and indeed the spoke protectors. If the bikes are not going to be used on road in the dark there's no real need or desire to have breakable and potentially sharp bits of plastic adorning them.
