Suffered the same fate. Broken rear hub because of over tension. The mechanic didn’t notice that part of the flange was already torn. I had to buy a fresh set of wheels. Fortunately, there’s a guy who needs the front wheel so we split the bill.
Now, the new wheel is untrue. It must be my weight (170 lbs) and poor road conditions.
I just hope Ming would come up with a better hub design or replace my broken hub.
