Okay, however you want to define it for yourself using your own personal definitions. I'll use Court's defining experience and the company's description and intent. So let's just leave it there.
In any case, it is a new design promoted initially by Trivel and reviewed by Court for EBR in October 2018. As Addmotor states, "it is the newest design of Addmotor of the Motan series. The new electric recumbent trike..." It was Court's review of the Trivel E-fat Azteca which intrigued me to purchase the M-360 which was crowdfunded by Addmotor at a low price..." It is loaded with electronics which I have not seen before on trikes or bikes for that matter and most of these were not even listed by Addmotor as accessories. Usually, turn signals are an aftermarket purchase as well as low and high beam front light. Having both a bell and a loud horn is innovative. In addition, all of these are mounted on the handlebar and easily accessible. They run off the trikes 48volt 14ah battery except for the bell which is attached to the left handbrake and is used manually. Having all of these electronic items mounted and easily accessible on the handlebar frees up considerable room for any other attachments such as mirrors etc.
As Court noted when reviewing the Trivel Azteca there is spin out with this type of trike if you are not careful when starting out with the throttle and since Addmotor placed a 750W motor compared to the Trivel Azteca's 500W motor there is considerable power. The wide Kenda tires create a comfortable ride with minimal bumpiness.
I would not have considered the M-360 or the M-330 if not for the Kenda 4X20 inch tires allowing for riding through soft sand to reach the beach at low tide and riding along the beach for miles on end. I live near the beach and until I purchased Addmotor's trikes I was unable to ride on the beach since I couldn't plow through the soft sand to get to the hard sand for riding. I have met other electric trike owners who don't ride on the beach simply because their tires are too thin. So, for me the 4" wide tires are a must and so are 20" tires which lowers the height of the trike making it more manageable. I wrote off other electric trikes simply because of their tires...too high or too thin. They had to be 4X20" tires or I didn't consider them. From what I have read tires need to be at least 3.8 inch wide to be considered "fat" tires although manufacturers use the word "fat tire" loosely when defining the tires on their bikes/trikes.
Most people walk their bikes through the soft sand but usually individuals who ride trikes are older and limited in their balance or have other limitations so walking the trike through the soft sand is not an option. For me, if I can't ride the trike through the sand then I am out of luck. The beauty of riding down the beach on low tide is not only the beauty of the ocean, birds, etc but there are no cars to watch out for and few obstacles such as angled driveways or crossing intersections. Riding an electric trike on the beach provides a new found freedom. In addition, Addmotor provides strong baskets with their trikes so if I wanted to haul a tent or fishing gear etc it would be no problem to ride to a spot on the beach, stop and put out a chair and tent to block the sun and read etc.
