My interest in this is two reasons. Up till now I havent seen a stretch cruiser frame that would take the trendy 4-inch wide fat tires. If you dont have suspension, I suspect a Thudbuster seat and 4-inch tires can provide adequate cushion up to the popular top speed of 28-MPH (45 km/h).
The second reason is that for snow (in Canada/Europe/Russia) I am convinced that a 2WD fattie is the best possible traction, even if you only need a modest 20-MPH (ie: not a hot rodder, obeys the laws, etc). Upon scanning E-fatbikes, I immediately see that a front conversion is the most popular. Many fat front forks will accept a REAR hub that has been laced to a fattie rim. The problem is the axle shoulders on the rear. Many fat frames are "just" wide enough that the common 135mm E-hub is too short.
If anyone had enough of a sales volume, it is easy to specify a longer axle in the hubmotor order. I don't know which retailers would allow a single-motor order with a longer axle (for a small extra charge, of course).
So, according to my best available information right now, the way to save a lot of money on a 2WD fatbike would be to look for an existing fattie with a rear hubmotor that is already using 48V (or 36V, but significant savings can be had if your desired system voltage is already stock on the model you buy). This model already uses 48V.
This model looks like a generic rear Bafang BPM, known to work very well with temporary peaks of 48V X 20A = 960W. Add a second $300 BPM kit on the front (the relatively "easy" part), and you could have a 2WD fatbike for around $3600, plus adding a battery capable of 40A peaks (cell_man 25R triangle pack?).
I like the low seat and the relaxed rider position, but that is a personal preference. Shipping to US is $150, and shipped from is listed Ventura, California. Aluminum frame, fork is likely to be "walmart" quality mild steel. Dual disc brakes are listed as Shimano hydraulics. So far the colors are black with red trim, and cream/off-white with red trim.
As a side note: with the stock 13-Ah battery removed from the seat-post slot, I suspect there is room for an LR "big block" (5 inches diameter) between the seat-post and rear tire (left side drive?). However, this idea is not yet verified...
If you want to tackle lacing a hubmotor to a 36H fat rim, here is a list I compiled for the available fat rims in 36H (almost all E-hubs are 36H), the list is at the bottom of this article. If you try this, please contact me on how it turned out, and provide any advice you can to help others in the future.
