I'm an American, 23-years old, living and cycling between Kobe and Osaka, Japan.
I commute by bicycle every day, formerly on a typical, quaint "mamachari."
Finally (with the help of this forum) I decided on a 2009 Bianchi Pista as my new fun bike for getting around the city. It's my first fixed gear bicycle and has been interesting to get used to!! Actually, I'd say I'm not totally used to it yet. (Pedal straps, aerodynamic posture, mounting and dismounting...) I love it, though, and have a lot of fun. Pedaling all 15 miles into the city is a real workout!
I'd love to hear back from anyone else in either city.
