i ride on our light-rail with my bike all the time & run into a folder there occasionally. imho they do not actually make it in the least bit easier for either their owners or the rest of us. you gonna fold it? please place luggage in the luggage racks, not take it to your seat. are you gonna leave it set-up as a bike? those cute lil things(?) are heavier & are awkward to hook into the limited bike spots on the train.
i don't get it...
