While the folding bike concept is cool, and it's actually really handy to be able to take them on trains where a non-folding would be disallowed, and while they are also more convenient than a full size bike, they're still big and cumbersome when folded up.

I can take mine on the bus, but that wouldn't be my first choice. I can take a regular Lyft, but not a Lyft Line with it. (I mean I could, but that's a dick move.) You're "that guy" at the bar after work.

Like I said, I own one (well, a Dahon), and it's definitely useful, more convenient than a full size, non-folding bike, but it doesn't actually solve the issue, merely alleviates it somewhat.
