Aipas M1 reviews/ feedback?

I'm considering one of these to be used almost exclusively for hopping from fishing spot to spot around the new England coastline. Seems like a lot lot of bike for the money, 1500 watt Bafang motor, Samsung batteries. It'll probably get used 20 times a year for a few miles at a time. Anyone been running one of these for long enough to offer some real feedback? All I'm finding is the typical "just got one and it rides great!" type stuff which is nice to hear but really isn't helpful. Thanks!
