次回この記事の日本語版を投稿します。

In Vintage Japanese Bicycle (Model Types)　④Ladies Cycle，I mentioned that in 1956, ladies cycles accounted for less than 10% of the market, and, only around 60% of women could even ride bicycles.  However, in the same year, Yamaguchi Bicycle Manufacturing Co., Ltd., introduced a model known as the Smart Lady which revolutionized women's models.  It is important to note here, that the term "Smart", means "Slim and Stylish", and it is this bicycle that ushered in a cultural change promoting bicycle riding, especially for women, as both recreationally fun, and, as a way to enhance beauty through exercise.

The company's design engineers focused on designing a model specifically for women.  In their own words: "This revolutionary modern bicycle is designed with the aim of promoting beauty through exercise and making bicycle riding fun.  Lightweight and durable, every detail, from the frame dimensions and angles, to the handlebars and saddle position, have been meticulously designed to help create beauty through exercise.

As we shall continue to see in this series, this is the model that gave birth to mama-chari.

We shall continue to see in the next installment in this series, how the Smart Lady became the original Mama-chari; a Japanese utility bicycle, or "mom's bike," designed for practical, everyday use.  The ubiquitous Mama-chari is the Dutch Omafiets of Japan.
