I apologize for any wrong terminology used in advance, as I am not very experienced with bikes.
My question is how do I get the disc brake and freewheel off?
I want to change the bearings as there is some amount of play, and while doing that I am replacing my brakes with hydraulic ones. I want to remove the disc so I can place a bigger one.
I unscrewed everything I could find attached to the hub. There were three socket cap screws on the backside and three screws around the radius. I assumed that this would be enough, however the disc and freewheel aren't budging.
A friend already broke a screwdriver (which managed to hit me on the head) while trying to pry it off from the inside.
The wheel is from a bike which I assume is a custom built motorized bicycle which I bought a year ago.

I’m not sure I’ve seen anything like this before can you take couple more photos? Is the cog fixed or does it freewheel?
Any close up photos from the back? That doesn’t look like any setup I’ve seen before.
I don’t even recognise the freewheel interface, could we get a close up of the axle on the sprocket side that’s in focus
I suspect there’s a threaded carrier on the hub threads that the disc bolts to, so the four notch splined silver ring should unscrew counter clockwise, but you’ll need to figure out the tooling you need
Is someone using a rotor as a dork disc?
Bodgy as my uncle Mike. I’ve learned so much from him.
My guess is that that bearing race/cup is also the lockring.
First, I tried googling for the instruction manual, but my browser gave me too many warnings for me to click on it. However from this pic, [https://content2.rozetka.com.ua/goods/images/big/400061787.jpg](https://content2.rozetka.com.ua/goods/images/big/400061787.jpg), the freewheel is threaded.
What stands out is the bearing cup has four tabs. I assume they are preventing the freewheel from being removed. These tabs also likely fit a removal tool, which is called a lockring tool. This isn’t the right one, but I include one to show you how it looks.

Now where you get this tool? Well, from Saiguan, with the infected website. Good luck.
How did this work on the bike? Did you have a brake calliper on the same side as the drive chain? That’s really strange.
