At the end of the day, it all about the ride. With such a small wheel, I doubt that the CG will be that much higher than if placed at bb. I have never ridden the e-brompton, so I have no idea how it rides. But with the motor config on front wheel, I think its possible to swap out the wheel and put a normal wheel so you can still use it like a normal brompton. Don't know whether you can take out the battery and used the bag for groceries though.
To do motor at bb, will mean a totally new and different bike. (Like Bosch config.) Just imagine the domino effects of trying to keep track of inventory, spare parts etc.
No, the motor is from Taiwan's BESV. The motor is not even a custom made for Brompton. They just buy whatever existing solution BESV had and put it on the Brompton. I have a e-Brompton but then I test ride the BESV and thinking this is way better than my e-Brompton. Mainly because the motor is on the rear wheel and so much more smooth. Too bad they don't sell the folding one in the US. I hate to buy e-bike from overseas because of the lithium battery regulations.
