As far as market group. I think the bike uses a fold that allows a straight chain without tensioner. So, fixies, SS, & IGH.
The advantage of a small mostly direct marketing company is that even if they only build and sold one packable BF a day, they could still build and make money on it.
My guess is that a lot of them will be used without particularly using the pack. Just a lightweight foldable bike. Maybe just use the pack for long-term storage and for travelling.

BF Fenders are fairly flexible, I think. So the fender may not be a problem (although it could throw it out of alignment).
