Shimano SLX M7000 11-46T
Discussion
I seem to be wearing out the rear Shimano SLX M7000 11-46T cassettes on my ebike quite quickly, about every 4 months. At about £50 - £60 to replace it's getting quite expensive, especially when replacing the chain as well.
Are there any other cheaper cassettes that I could try? Possibly where I can replace individual spindles? I seem to wear gear 10 & 11 before any other.

Not sure I'd agree with this. Normally, cheaper is heavier so wears more slowly. You pay for lightness which often equates to softer materials.
Each to their own.Heavier due to lack of, for instance aluminium spider. softer due to, inferior plating and grade of metal.
Working with new bikes from £350-£15000, I'll go with my experience along with my personal test beds.
I knew what the answer to this was before I even read your post. It was quickly confirmed.
The answer lies in your own explanation...” I seem to wear out gear 10 and 11 quicker”. This is very common with e bikes, because you have so much assistance you do t change gear like you would have done and are able to pull away and pedal in higher gears than is usual. Due to the increased speed, torque, heights climbed, you are wearing everything much quicker than a normal bike also.
Add these 2 situations....not changing gear and riding in a high gear together and you have very high wear rates on only a couple of cogs with far fewer teeth. You will also be wearing you chain quicker. Shimano also do e bike specific chains which are stronger.
You need to use the gears and back off from riding around in turbo mode otherwise you need to accept the high wear rates.

I already know why it’s wearing out, but my question was can anyone recommend an alternative cassette, or one which separates so I can replace individual cogs instead of having to replace the whole cassette?
You can get individual sprockets from places like SJS. There are no cogs on a bicycle, unless you have hub gears.You can’t get the individual sprockets that make up the cassette as they aren’t carried in the UK. It might be possible to find them globally, but I doubt it. You’ll almost definitely need to buy a new cassette

I would go at least xt cheaper mostly wear out faster as not all Have the same coating, decent chain should last say two three per cassette,if you don’t measure the chain it will ruin the cassette, person I ride with had a billet sram cassette,now he does winter season and summer season msg still going 5 years later .

This lot have individual sprockets, and the shipping is usually quick and cheap.

The chain will be wearing quicker than the cassette, once the chain wears it'll increase the wear rate on the cassette and you'll need to change both.
Replace the chain before the cassette starts to wear and you can potentially get through 4-5 chains before having to replace the cassette.
Using a range of gears will help spread the the wear.

There's a couple of ways to go:
XT is better than SLX, but really it's designed for better performance, lighter etc. I wouldn't bet on it being better wearing, if anything worse. I killed on in 4 months through winter.
The fundamental 'issue' with Shimano cassettes is the often use Alu sprockets to achieve good weight (it should add that I don't know if all the sprockets are Alu, or just the low ones or indeed if that's specific to XT and not SLX).
The old answer in the 9sp era was a Deore cassette, that's sub-SLX so they're cheap £30 or less and they NEVER wore out, the downside being they were 100% steel and weighed at much as the moon, whether that's more or less of an issue on an E-BIke, that's up to you to decide.
SRAM is another animal, they use steel sprockets, but they use light-weight mounting spiders so you get lightweight and hard wearing, the downside is cost. GX which is supposedly par with SLX will cost £150, and they're not compatible with Shimano anyway.
Long story short, SRAM make an NX line which comes in 10sp, 11sp and 12sp and will probably work with your set-up. They're sort of XT money, but should be harder wearing.
Alternatively, try a bigger front ring to try to spread the load across more gears. I've only borrowed an e-bike for the weekend, but even riding the Gap trail in Breacon, all but the highest maybe 3 gears were completely redundant, you could pull off on the flat in top and maybe 5th on the steepest part of the route. I guess they were under-geared mostly so you'd run out of gears about when the limiter cut in?

Thanks for that information, very useful to know. XT is better than SLX, but really it's designed for better performance, lighter etc. I wouldn't bet on it being better wearing, if anything worse. I killed on in 4 months through winter.

I ride mostly in either gear 1 & 2, or 10 & 11. This is because of the really steep hills on my daily commute. On my way to work it’s down hill or flat, so I’m in gears 10 & 11. But on the way home I’m climbing up those steep hills so I’m in gears 1 or 2. It’s why I bought an ebike as the steepness it too great for me to get any pleasure from cycling up them on my non ebike.
Being able to swap just the worn sprockets would be ideal, but it sounds like I’ll just have to keep splashing out for new SLX cassettes maybe 2 or 3 times a year, interspersed with a few new chains. Not particularly cheap though.
Here you go, replacement tenth and eleventh gears, £1.37 each.

The XT cassette has one alloy sprocket, and that’s the 46. Never noticed my XT stuff wearing any quicker than any of my other stuff, including nine speed Deore.XT is better than SLX, but really it's designed for better performance, lighter etc. I wouldn't bet on it being better wearing, if anything worse.

Main advice is to keep everything clean and lubricated correctly.
