is poor wheel building and materials. They also use bigger-gauge spokes and have caused the issue too.

Send your hub motor to a professional wheel builder.
It's worth the money.
Adding hundreds of dollars to the cost of a new ebike to have the wheels professionally built, isn't something that normal customers are willing to pay for or even understand.
Just like a proper air suspension.

Sounds like you are riding the Snot Outta your ebikes?
If you're gunna ride it like a Bronco, you need to build it like a Bronco.
A Heavy hub-drive wheel needs to be built properly if it's going to be ridden hard.
Proper spokes and nipples can be over $200 alone.

About spoke gauge and how that effects spoke breakage. A spoke needs to be properly tensioned to resist failure. A thicker spoke needs more tension, and the rim would need to be able to withstand that tension.
What's commonly done on some commercial ebikes is to install 12 gauge spokes on rims not able to handle the extra tension. If the spoke holes in the rim look like they're pouching out, the rim has failed and spokes will break at the nipple. Spokes will continue to fail, even if replaced.
Carefully inspect the rim spoke holes at the broken ones. If they are distressed the rim is toast, and you need a new wheel.
Lacing a motor into a rim isn't all that difficult, kind of a relaxing evening thing to do. Grin has some great info and videos.
It's still going to be north of a hundred bucks for a rim and spokes.

Well within the weight limit of the Level 2.
My first Xpedition rear wheel started breaking spokes and Lectric covered it under warranty. They authorized a bike shop to fix the wheel and sent new spokes. I had a wheel building pro rebuild the wheel for me and never had a broken spoke since. It was just poor and inconsistent spoke tension from the wheel building machine. They when my tire came off the rim (covered in another thread) and got a flat spot I ordered a new rear wheel from Lectric, figuring he wouldn't be able to fix the original wheel. I had him go over the new rear wheel before installing it and he shocked me by fixing the flat spot! So now I have 2 good rear wheels for a Xpedition. Oh, my Xpedition gets worked hard with 2 adult passengers bombing around on a regular basis.
Short answer: Machine built wheel = inconsistent spoke tension. Have someone good go over it or learn spoke adjustment yourself (I've never been good at truing wheels).

No matter what, if the wheels are not built by someone that knows what they are doing, you need to have the wheels checked after several hundred miles, even on a decent bike. People just hop on these bikes and go.
