I asked chatgpt for you: https://www.walmart.com/ip/26-FAT-E-BIKE/8482660387?wl13=5864&wmlspartner=wlpa&selectedSellerId=0
You can get one of these and add a front motor and extra battery: https://www.walmart.com/ip/8482660387?sid=082b3ac6-8ba9-420b-8520-6819847ffd89
If other posts haven't convinced you to avoid a fat bike; have a look at the Ozark Trail Ranger. Any bike crate would fit onto the pre-installed rack. However, I would agree that this is probably not the best way to go. Fat bikes are very heavy, and something lighter would probably make it easier to handle. You can always go with wider tires and run lower pressure in them to get some of the smoothing benefits.
