First Ebike for committing

[Bikeyearround]

I've been an analog bike commuter for years. Having the choice to pay for parking or bike, I chose to bike. In the past I would drive eleven miles and park where it's free, then hop on my bicycle to bike the last mile. I was inspired by seeing a commuter on a Fat tire Ebike. In my car I would pass this guy about 3 miles from work. By the time I would park my car and bike to work this guy was always ahead of me just getting into work. I borrowed a friends class 2 Ebike and tried commuting from home for a week. Before the end of the weak I was sold. After a couple weeks of researching Ebikes and test driving at my local Ebike store I decided on a Fat tire (for better winter traction). I also knew I wanted a class 3. The class 2 I borrowed would completely cut out all motor assistance when I hit 20 mph. This became a disincentive to bike my hardest knowing all assistance was gone as soon as I hit the 20 mph mark.
I decided to buy the Biktrix Juggernaut Ultra 1000. It seemed like a great deal for a torque sensing, 1000 Watt, mid-drive fat tire. Came with fenders (a must in all weather commuting) and hydraulic brakes which seemed important for such a heavy and fast bike.

The bike arrived a week earlier than expected! Only one week from purchasing to arriving in WI from Canada! Took for my first ride that night, I could not wait! It was making a weird squeaking sound. Thought is was the front fender but nothing was rubbing. Got back to the light of the garage and saw that the rear tire was rubbing so bad the writing on the tire had been rubbed off and there were rubber shavings all over the wheel and drive train. Customer service was initially responsive. They asked me to send pictures of the rear hub. They reviewed the photos I sent and they responded: "It doesn't look like there are any washers between the hub and the frame. There should be 2-3 washers on both sides of the hub. Are those present? " I informed them there was one washer on the left side and none on the right two days ago, but haven't heard another response.
For now I'm stuck with a $3500 awesome bike that I can't ride without the rear tire shaving away. I'm starting to question if this frame might not really accommodate fat tires properly. Waiting on customer service to tell me what to do.
Is is really possible that the design of the frame requires "2-3 washers on each side of the hub" to accommodate a fat tire?
I've attached the link to pictures of the rear hub Biktrix requested I send them.

I can't wait to start biking to work from home once I get this issue figured out. I can't recommend Biktrix until I see out they resolve this issue.

I bought the same bike about a month ago. I can't say I had the same problem you mentioned but I will say I had to adjust the disc brakes which were rubbing a bit. If you don't know how to do that check out the following video:

In most cases you just need to true the calipers but make sure the rotors are true as well by spinning the wheels and making sure the rotors aren't wobbling. Also check the trueness of the wheels themselves by spinning them and viewing the tread head-on - they shouldn't wobble either. Now, I'm not sure if Biktrix trues the wheels - mine were acceptable but if they're out then you'll need to true them up using a spoke wrench or just take them to any local bike shop and have them true them for you. I've never bothered with wheel truing myself - it's too much of a PITA and I'd rather pay the bike shop to do it. Regardless, highly recommend you take your bike to a local bike shop and have them check your setup. They should be able to dial everything in for you for relatively little charge. Finally, there is a Biktrix-specific forum which Roshan (the owner of Biktrix) monitors. I'd post this message there.

Update. Roshan at Biktrix is working with me to resolve the issue. He offered to either have my frame swapped out for a new frame when new frames come in or send me the 27.5x3 wheel set to fit my existing frame. The customer service through the Biktrix website didn't offer as much help, but contacting Roshan through the forum on this website worked!
