I just returned to (more) serious biking after an absence of almost 15 years ... Tokyo is a fun place to ride, in its own trafficky, narrow, busy way. The streets are generally well maintained though, which is nice; and almost no trash & glass in the way.
I've been riding a single speed (Schwinn Madison---using the freewheel rather than fixed for now) borrowed from a friend. It's quite a bit too small as it's the S size frame (51cm?) and I am 6'4''. I found this forum via looking for internet resources as I decide what to buy. Current questions: aluminum vs steel, road frame (for conversion) vs track, geometries ... Enjoying.
