They are fold able but certainly more clumsy when I see them on the train. Also a lot more expensive and yet another thing you gotta charge and eventually replace a battery for. Its also a 30lb hunk of metal still, not everyone can comfortably tote that up and down train station steps all day. Most people I see don't even fold their escooter on the train just hold the handle, roll it in and have the tail out and let people deal with stepping over it. Makes me think transit as we know it wouldn't even work if everyone got one of these things or an ebike and took up so much extra space as a result.
