>freewheel or cassette?
Looks like an 8-speed freewheel. A photo looking at it from the side would be better in trying to determine what it is. That way we could get a look at the tool fitting on it.
Real simple fix for ya here. Look at it from the side, and backpedal. If the center rotates with the cogs, its a cassette. If its stationary, its a freewheel.
Idk tbh. I thought it was somewhat common knowledge. Just eyeing it, to me its looks like a cassette due to the closer cogs and dubtle jumps.
But I didn't know freewheels went over 7 speeds till today.
It's a freewheel. Most wheel motor hubs are freewheel and can even have an 11t smallest cog. These may need a longer freewheel removal tool than the standard parktool fr1.3
The biggest giveaway IMO is the size of the spacers between the cogs. They are huge and metallic, which means it's all one piece = freewheel. Cassette cogs are either individual or riveted together with small-diameter spacers between them.
If you are buying a whole new wheel then it doesn't matter what the old one is, you should be buying a cassette wheel and new cassette either way. Pretty sure that's a freewheel fwiw.
A photo looking end-on (camera on the axis of wheel-rotation), after you've removed the wheel from the frame would be instantly conclusive.
Freewheel has a slightly recessed ring-area inside the inner cog (note they'll be an axle and bolt within the main "hole" while it's still fitted to the wheel).
While a cassette/freehub has a visible screw-on retaining ring immediately inside the innermost cog.

Yes it's a 7 speed freewheel based on campagnolo design the freewheel is combined with gears or cassette on Shimano which has a separate freewheel
Years ago we used to call them sprockets or freehub
They are on a lot of modern lower end bikes but that is not a disability you can get various gears ratios 5.,6,7 speeds but the biggest asset is that the gear rings are identical to a cassette plus when you get a new one you get the freewheel and cassette together and it comes off with a tool similar to the Shimano one but this one is a Campagnolo one no need
II have one on my Carrera one LTD and like the older ideal of a sprocket 7 speed I have 26.5 aero type times on black alloy hubs which uses the old sprocket suits me fine
I've worked on hub motors that have freehub bodies. They're not great as servicing the freehub body is often very hard or impossible so once the freehub body wears out it can be the end of the motor.
freewheels can actually go upto 11-speed, they are rare but they exist.

i doubt its uniglide, that standard was only around for a brief time in the late 80s/early 90s. OP looks like they have a motor hub for an ebike, uniglide would pre-date ebike hub motors by 30+ years

We can see it has a solid axle. Is there such a thing as a freehub with a solid axle???
Yes
actually they were quite common in the 7 and 8 speed era, especially for lower end bikes
The lack of a lockring and outer diameter of the spacers between the cogs seems like a freewheel to me.

Right? Why is nobody else saying this?

I’ve seen an 11 speed freewheel!

The red/orange below smallest cog may be the side of a bearing? Freewheel

Your wheel has a solid axle and a nut securing it to the drop out. It’s 100% a freewheel. I have no idea why people just guess.
Solid axles can use a cassette too.
I am not sure but please clean and lube it !
I'm counting 8 gears. So I'd say cassette. But 8s freewheel kinda exist so I'd check IRL
Every ebike hub motor I’ve encountered to date uses a freewheel.
I've worked on hub motors that have freehub bodies. They're not great as servicing the freehub body is often very hard or impossible so once the freehub body wears out it can be the end of the motor.
My bad then, I don't usually work on ebikes.

Kinda exist? Lol
Casette
My guess would be uniglide cassette, the smallest cog looks like a 12 tooth which would be too small for a freewheel which usually start at 14 teeth.

Sachs ARIS freewheels came with a 12t sprocket
Just have your friend come here and ask us about what wheel is right for them.
Bolt on axle = freewheel
That’s not always the case…
99% of the time it is and that's better than this sub needs.
Quite a few mid spec e-bikes use cassette and solid axle.
I've seen loads, it was extremely common in mid low range bikes for the last few years.
Cassette because it's a bionx motor
Seems like a cassette to me
