It is a low initial cost e-moped with a lot of no-name parts. The wheels are boat anchors and not able to be trued, the brakes are from some unknown company (but at least look to be hydraulic which is generally better though without knowing who makes the brakes it could be irrelevant).

Fat bikes are fun but do best when they are a bit lighter and on snow and sand. If you are going to be riding on snow and sand more often I would say a fat bike could be practical. For going around the city or normal trails or paved trails probably not the bike and will be heavy. We had quite a few fat tire e-mopeds similar to this (under different names) and trying to lift one was never easy.

I would recommend telling us what you are looking for in a bike or what you need and where you might be riding and things like that so someone can give more useful feedback on what bike to get. If you are just shopping based on initial cost then pick 6 internet bikes (or e-mopeds) assign them a number between 1-6 and then roll the dice chances are they will be pretty similar. Pretty much any e-bike or e-moped will be fun on a first ride or on the first few rides long term is where the cracks show.
