I'd argue that part of the reason you're paying a higher price is BECAUSE they're more customized, and companies like Trek spend a lot more money on R&D to get to their frame designs.
EBC has essentially 3 frames (5 if you count the integrated rack for rear battery models of their regular and step thru), and build out from there. All are what I'd call "utilitarian" or "casual cruiser". There's nothing wrong with that, and that's their market.
The "big" bike companies all have much more purpose built frames. From road to eMTB, to casual cruiser, and there's no mistaking one frame design over another. Using Trek as an example, they 8 or so frames just for their city/casual bikes alone, from lean back cruisers like the Ace of Spades, to more aggressive frames geared towards city commuters like the Allant 8.
To bring it back on topic, if you're looking at something like the Allant 8, but want front suspension, there's the Allant 7 just waiting (in 3 frame styles). If that's not "mountain bikey" enough, they have a range of hardtail and FS eMTBs.
