I am afraid we can only choose from the limited selections available in Japan. And we cannot try the bike before buying. Even ordering a frame size not in stock means paying up front and accepting without ever even standing over it!
We have two folding bikes but they are useless for touring in Japan due to the extremely mountainous roads.
To be honest I do no think she needs a "girls" bike. At the moment she is riding a Specialised Sirrus Comp. She has zero problems with this bike in terms of riding and comfort. Unfortunately, it is starting to fall to pieces after only two years. Hence, the search for a new bike. Also, we want a steel frame so that it last more than 2 years! I am riding a Surly but it is a bit on the expensive side here, though I know if would be a good choice for her.
