I just completed a relocation to Korea and now I think it's time for me to get a folder. I read the faq but still not sure what might be best. I live in a high rise and probably will take the bus from time to time with it. So that means small folded size and folding speed are important. I am 5'11" and 170. I plan to ride every day. Having the option for good winter tires would be nice. So far I am looking at brompton, bike Friday, and maybe birdy. There are tons of local options available, but i havent seen any as nice as the above options.
there ya go afaik there are 20" studded tires, Schwalbe , for winter,
but the 349 , 16" wheels make a nicer smaller fold.. and offer a higher pressure easier rolling tire.
That's one of the things I read about the birdy -- the "18 inch" tires and wheels can be swapped for 20 inch tires and wheels with a brake adapter. Just not sure if the fold is compact/carryable enough with a dust cover for semi-crowded areas/bus.
My Bike Friday pocket Llama, has disc brakes , though It wont fold as easily as one made to do so rapidly .
Its my wet winter bike ... [I have an old MTB wearing the studded tires when the temperature
drops to Icy roads.]
the company since has introduced their Silk model , with a 20" wheel will take a belt drive, so chain dirt is gone.
and appears to fold some what easier..
But .. the NWT and the PL offer derailleur drivetrain options, some may prefer ..
