I was hoping that I didn't have to remove the display. But, it is what it is. Did you get large fat tubeless tires? I was told my tires are too big at 2.125? I also have seen articles about tubeless tire maintenance which seems daunting. I'd really like to know where I can get tubeless for my wheels particularly the brand name. Nice bike!
Note in my picture of the Haibike Full FatSix I posted in post #2, I have bar ends. These are not as big as the Ergons posted by Tcombest. Mine are Cane Creek Ergo Control Bar Ends. Link:

I have those Ergon bar ends on my Trek Soho DLX. They are made of a hard nylon and are exclusive only to the Ergon style grip. When I went "fatbiking" first with my Specialized Fatboy and Haibike Full FatSix, I went with the Cane Creek Ergo bar ends based on positive reviews on MTBR. The Cane Creeks fit nicely in the palm of the hands and the kraton rubber is soft (unlike the Ergon's) which help absorb road and trail vibration. Plus, they help balance the bike as well as providing a touching point with the ground in those times I was fixing flat tires with the bike upside-down. With they Cane Creeks, all you'd have to do is loosen up the grips (if they are the kind designed to be secured with a screw on the grip itself), loosen up the brake handles, shifters and just slide it all on the handlebar inward about a half inch or so to fit the Cane Creek Bar end, then fit everything back snug....
The Haibike Full FatSix is a fat tired mountain bike and those tires and rims are part of the bike's group set. Tubeless can be done on most every bike, but best to ensure your tires are "tubeless ready". When I set out to go tubeless on my Haibike, I started using brand new Jumbo Jims as I had a lot of wear on the older tires & I just wanted to start fresh....
Setting up tubeless, I used flashing tape made by Zip, found in Home Depot. Cut it to size to go around the rim; the side benefit is it is very, very pliable; which aids in sealing the rim. There are countless videos out on the internet on how to do it. This is the one that helped me the best as I went about doing it on my own:
And here is another one from Park. You cannot go wrong with any of the fine Park Tools bike maintenance videos on youtube, IMO:
