Women: the pawns in this battle.
Cycle Chic, whether in Copenhagen or Pyongyang, is practiced today as it was in the 50s and 60s by England's Sloan Rangers. By the time The Official Sloan Ranger Handbook was published in 1982, the style's every nuance and rite had been well bedded down, and this while Mikael Colville Andersen was still doing jumps on the PK Ripper Julemand brought him for Christmas that year. It must be said too (and I'll be lumbered with holocaust deniers for letting this out), that the percentage of trips by bike in Denmark in 1982, was a flat 0. Unlike porn, it was illegal!
From The Official Sloan Ranger Handbook:
You always bike in the same gear you wear in the office [...]
You're not very hot on safety gear and helmets and goggles are for fanatics. [...]
Sloan women always have large wheeled old bicycles (no idea which make) with huge wicker baskets in front. Top of the class are sit up and beg [...] bikes. [...] You never have drop handlebars or more than three speeds. The bike is usually dirty, beginning to rust and in need of an oil.
In fact nothing a Cycle Chic blogger has said about clothes, steely daring, equipment, or how to be, cannot be found right there in black and white in The Official Sloan Ranger Handbook.
