I will write about some minor/personal consideration. I found a billboard which shows "安いだけで(買って)はだめ 買って安心 修理がきく" while jogging at Nagahama. This is a bike shop's billboard. It may be translated " You should not buy it just because of its fair price. We serve full maintainance, which makes you feel safety." I agree with the phrase because the maintainance/promise will reduce customer's cost. On the other hand, a bike itself is not expensive and a bike itself is not broken easily. So I don't think it is important to assure the mainatnance for free. Of course, we encounter a flat tire sometime, but it is not a serious issue.
I don't know that how often people need to fix their bike outside Japan. I personally notice that people who live in San Francisco need to ride uphill and down hill. Especially when they ride their bike downhill they use break much. That's why they need more maintainance than people who live in Japan. I personally think the more important thing is how to ride downhill safely. Yes, I think what is the problem when people in Frolida ride a Mama Bicycle with their children. I am wondering what is the critical problem for them.
Ah, I saw a mother ride a Mama Bicycle at Nagahama yesterday. Nagahama is a suburb where cars are dominant. But she naturally ride it with her child. Some people seem to ride it in such a suburb.
That's ll for today. Thank you...
