My son has that ebike. And I have the A9.

There are some cons to the Aniioki ebikes:

A lot of their components are proprietary which makes replacement dependent on what Aniioki has in stock. And of course you are subject to whatever price they want to charge. I will say I have replaced a throttle and a controller and the cost wasn't much different from similar items from Amazon.

The ebikes are heavy. REALLY HEAVY. Pretty close to a small motorcycle.

The gear ratio if you want to pedal is atrocious. The lowest gear isn't really suitable for starting at all.

The A9 version is very high. And even with the seat at its lowest point, it's not comfortable for a short or average height person. This is the reason my son got the A8 instead.

The tyres are bigger than most fat-tyre ebikes. Mine are 26x4.8(inch). And most fat-tyre ebikes I see are no larger than 4.0(inch).

Now some pros in my opinion:

Very good range. Riding with throttle only, I can go around 90 miles without recharging. Pedalling will get you more range, but probably nothing near what they claim the range to be. I usually cut their range claims in half to be realistic.

The ebike is virtually indestructible. It's heavy-duty to be sure. Built like a tank..lol.

Seats are actually comfortable. I can ride as long as I like and not be uncomfortable.

It's a pretty smooth riding ebike. I've ridden smoother ones, but this one is better than most in my opinion.

I had no problems assembling and setting up the ebike. Controls and settings are easy to access. And they do include two fobs. (Don't lose both or you will be without a ebike until you can get replacements sent.)

All in all, I'm satisfied with this ebike (and my son likes his as well). For sure there are better ebikes out there though. You will not get 150 miles on one charge with this ebike at throttle only. You MIGHT with some decent pedalling though. And the cost is going to be more than your specified range.
