Thanks for the vid. I have a 142mm axle and am using the Lekkie 42 tooth narrow wide Bling Ring. It's made just for this, perhaps an oversight on Bafang's part. It's made of 7000 series aluminum and is offset is approx. 12-13mm (difficult to measure when installed). Barely clears the frame, but it clears and the chain line is near perfect on a 10 speed cassette. I have about 3000 hard miles on mine and no signs of wear. I think it was $70 or $80 which seemed high at the time but it is worth it. My clearance looked about like yours with the stock chain ring, the 2 tooth smaller diameter of the Lekkie make it work. Regarding the battery mount, I would try reversing it (180 degrees). Counter intuitive as that may look when standing still, once your thrashing around on the trails you realize the lock is what holds the battery in place, not gravity. Also, the two water bottle bolts were designed to hold about 3 pounds, so I use straps like yours, but not elastic.
Thanks Barclay! The 1.8mm offset of the 11s cassette makes chain line worse for the largest rear cog. There is a Chinese chainring called Gustavo that has similar offset to the Lekkie, maybe still too much for my bike.
Yes the brake sensors aren't ideal and aren't very reliable (depending on user install). On the other hand if you stop pedaling, the motor cuts off quickly and you can unplug the sensors so you won't have to worry about the motor cutting off. I've adjusted the sensors so I have to pull the brake levers almost all the way in before it engages. Thanks for watching!

Good job… but those brake sensors are sketchy 😂
