I have the Aniioki A9. It is built like a tank...and weighs in like one too. It weighs almost as much as a small motorcycle.

It does have good range (I can get around 90 miles on one charge with throttle only). It has decent power with good climbing ability.

The seat is quite high even at the lowest position. If you are on the short side, it might be too high for you. I am right at 180cm (71 inches) and I can barely stand flat-footed while on the ebike.

The tyres are a bit larger than most fat-tyre ebikes. They are 4.8 inches as opposed to a usual max of 4.0 inches. I can't really see a downside to this other than less options for replacement tyres.

Charging time is long (usually around 7 to 8 hours if the battery is fairly low).

It has a comfortable seat. I can ride indefinitely with only very minor discomfort. The suspension is a little stiff compared to some other ebikes, but it's still adequate.

Price isn't too bad compared to other ebikes with similar features.

Personally, I like this ebike. Could it improve...definitely. Are there better ebikes...again definitely. Am I satisfied with it all things considered...yep.
