Help finding a wheel replacement

Hey guys. I'm thinking of converting my stock Rad Rover 5 to a mid drive motor instead of a hub. The problem is I can't seem to find a 26x4 fat wheel that can accommodate the cassette and disc break.

Would buying an entire wheel be my best bet or would I need to resort to buying a wheel hub, spokes and build one from the old rim? Where should I find these, ebay?

Unfortunately, I live in a rural area without access to a good bike shop and this is my 2nd conversion so any help, feedback or suggestions is much appreciated.

I'm not positive the Rover uses a 170mm wide hub/motor, only pretty sure. If that's the case, I've found that 170mm wide hubs just about impossible to find anywhere. Been looking for weeks and have come up empty handed as I need one for a different project - converting a mid drive fatty to 27.5" wheels. Everything I've seen available is 148mm or smaller.

The second issue you have, will be the axle size. Those are going to be hub specific as well. The Rover frame is set up for a hub motor. You're going with a conventional (but heavy duty) wheel.

The rim is itself is easy to find - if you are going to stay 26x4. Just make sure the number of spoke holes in the rim match the number of spoke hoes in your hub! (32h vs. 36h)

Could you just remove the motor internals from your old wheel and retain the Bafang case. Probably need to fabricate a new axle.

Sell it before you stick money into it and buy what you want.
I've been down your rabbit hole before and it never pays off for me!

As AHicks has said, you will find a rim, no problem, but everything else is going to be a chore!

I am just brainstorming here without going into the details, counting spoke holes, and fully researching your project. The idea is to keep the existing rim and lace in something like a NuVinci cargo/commercial hub. A section of pipe could be used as an axle spacer if required, but there is also axle length. Chain line will be a big consideration. It would take welding and risk.
Yes, It is better to sell and start with something where it will all work. People are nuts over the cargo bike conversions with a mid-drive. And they do not need to look a backyard pit-bull breeders' junkyard bike. You can start with any bike you like for your style of riding.

Agree with u , Rads generally have great resale value so sell that Rover and buy / build a mid-drive.

Regarding the link above, I followed with much interest, which takes you to another web site (Bikeman.com) where you find out the Cater hub is only available in a 32 hole - which is fine if you are working in a bicycle. Most e-bikes, all that I have owned anyway, are 36 hole (36h). Speaking for myself, the search continues....

As far as converting/coming up with a new rear wheel, I think it's a safe bet to plan on 2-400. for the parts, and that's like I said earlier, depending on finding a rear hub you can use.

Assuming you could get that "gutting the geared hub motor" plan to work, that's going to leave a lot of extra weight back there.

It literally took me 5 seconds to find one on AliExpress.

Rad uses 170mm hub?
If that's the case, those 190mm from AliExpress won't fit.
Some seem to be 170mm though.

It depends.
If OP's objective it to get a mid-drive fat bike, you'll be better off selling the Rad Rover and just replace the bike.
However, if OP is a hobbyist / enthusiast, then it's a different story.

I've seen so many motorcycle enthusiasts modifying their bike, wider piston, longer conrod, cam upgrade, exhaust, etc..
People would just tell them "just sell your bike and replace it, it will be cheaper"
But it's a hobby, and it usually doesn't make financial sense, and it's okay for a lot of hobbyists.

I did find a hub that would work for my purposes (I hope) on Aliexpress. Long story short, I had been beating the bushes for so long, that when I found one in stock (supposedly) that checked all the boxes (not as easy as it sounds) I went ahead and ordered it. Though I've purchased direct from Chinese vendors many times, AliExpress is not not my favorite source, but in this case I took a gamble and gave them my info via PayPal.

The one I ordered is the KT-S7LR here:

Everything about the bike I love. I just can't climb hills including the 18 degree slope up to my house. :(
