it is nice to finally receive a motor not damaged in freight...
Mine is unuseable. I installed the wheel correctly but the motor wobbles around the axis and makes the bike vibrate at higher speed. I also can't use a disk brake because the disk moves to much left and right because of the wobbling motor. I opend a dispute and uploaded a video that clearly shows the problem but the seller is not offering me a acceptable solution. So i've to return the whole wheel on my own cost (aliexpress will provide a 20 USD coupon) to get a refund and buy a new one somewhere. I'm disappointed because i lost a lot of time and money. The seller wasn't helpful but at least polite and answered fast. Delivery took about a month.
