That's kinda neat. I didn't realize there were any mid-drive kits that could be retrofitted to a normal BB. All the mid-drive setups I've seen are big bricks. But then, I'm not in the e-bike market (except for the new ones that go through our shop).
Still, it would be best if the battery were mounted low in the main triangle. Like I said, a horizontal mid-tube (like on the Rosco Road bikes) seems like a nice place to frame that battery. Riv's long chainstays also could provide vertical space behind the seat tube. Obviously that's not an option on a folding bike like yours. Yours seems pretty well-integrated, given the challenges.
