There is in bikes.
I didn’t really want to get into details of the particular thing that prompted this post, because then there’s going to be too many people posting suggestions they think are helpful, and that would be missing the point. Suffice it to say that I’m cobbling together pieces from YouTube, forum posts, and old Reddit threads that, IMO, I would expect to see more consolidated. In times past, I think it would be. I do think I’ll get there in the end, but it feels much harder to get everything together than it used to be.

Other than ebikes?
And e-bikes are just circuits, or otherwise proprietary components. You’re gonna be following manufacturer guides, or likely videos, so use site results to specify.

There’s a lot of parts changing around them, yes.

A gear shift is a gear shift, a brake is a brake, a motor is a motor…. Sounds like your ignorance is the issue here.
The tech isn’t new dude, you just can’t figure out how to find the information and want it spoon fed to you, you don’t want to learn. You want stuff on a silver platter, and you’re exactly why Google has shifted this route. Wow.

Yes, ignorance is the issue. I don’t know how to do something, and I’m researching how. Good job. Also:
You can shut the fuck up, because the stuff I’m looking at isn’t decades old. Or more accurately, has technically existed for a while, but wasn’t common until the last few years because of changes ebikes are driving.
Fine, I’ll go into details. Derailleurs suck for ebikes. They can’t really take the torque the motors can output at class III levels. I’d like to make the conversion over, and there’s a lot of pieces that go into that.
I converted a bike with a 750W Bafang kit. I changed up the derailleur, but I had trouble aligning it. I took it into a shop and they aligned it, and it actually made the problem worse. At this point, pretty clear this just isn’t the way to do things anymore.
So look for alternatives. Internally geared hub seems the way to go. Have to rebuild the whole wheel. That part is long and tedious, but Park Tool has pretty good tutorials on it. I have access to a makerspace that already has most of the tools I’d need.
Park Tool also notes that 3-cross spoke patterns are common, and most tutorials out there show that. Problem is, internal gear hubs are larger than normal and it probably can’t fit a 3-cross pattern. Have to go down to 2-cross, but still need to find a tutorial on the specifics. There’s a certain way of doing things so you get the pattern correct around the entire wheel.
Spoke count on the hub needs to match the wheel. That and the pattern determines spoke length.
So far so good. All this is doable.
The next problem is stuff directly around the hub. Specifically, gathering compatible parts. Without a horizontal gear mount on my bike, will need an adapter. Disc brake mount should be fine; just don’t make the mistake of buying a cheap gear hub with a coaster brake. Those suck and arguably shouldn’t exist.
Then there’s other parts around the hub that are needed to mount the whole thing. This is still where I have open questions, and Google and YouTube have not been helpful. Product page for the hub simply says “additional accessories needed” with little detail.
Add on the possibility of going to a belt drive. That shouldn’t be too bad. There’s an adapter plate out there for the Bafang mid drive.
Now, does this sound like I haven’t even tried doing research, or that I just want all this handed to me? No, these search tools suck. And if you haven’t even done an ebike conversion on your own before, then you can shut the fuck up.
