For BART at peak Commutes, How about a Bike Friday Tikit.. Made in Oregon, and they fold swiftly
you roll the folded bike by its front wheel, with a handle , part of the folded rear portion.
they start at/under about $1K you can get them in Sizes, so unlike any other folding bike.
+ as you offer more $ you get lots of upgrade opportunities..
they will love to go with a premium component pick..
off peak you can take regular bikes .. good town for theft, so if you have to lock it outside
Consider coping with it being Not there.
May be some of the Craig's list sellers selling what they took.
