I haven't really seen any guys carrying a bike into the train - just saw them riding on it in the streets.

It's a bit too late for me to buy a lighter one - I inquired about it, and they seem to cost around $400, which I certainly cannot spare right now. Okay. 14.1kg. Sigh. As if 1kg would make a difference.

It's not even a Shimano, my bad. Seems like it's a relatively unknown brand. http://yutjapanbike.igetweb.com/catalog/p_31219.jpg

It folds up similar to that. Certainly a bit awkward to wheel unless I pull the saddle in all the way down, and even so I can only wheel it forward, trying both ends with a rope to keep it together. Perhaps I will. But it seems that in Japan they require bikes to be carried in bags - I'm thinking of simply covering it with a bag, exposing the wheel, and wheeling it. Don't know how viable it is unless I try it.
