the Bicycle did “more to emancipate women than anything else in the world” ... Susan B Anthony

In June 1895, the Unique Cycling club of Chicago had a club laws that on all runs bloomers and knickerbockers shall be worn.

In New York World, a list of rules for women on bicycles was posted (and seem ludicrous now)

Don’t be a fright
Don’t faint on the road (Still a good idea)
Don’t wear a man’s cap
Don’t wear tight garters
Don’t forget your tool bag (Still a good idea)
Don’t attempt a “century”
Don’t coast. It is dangerous
Don’t boast of your long rides
Don’t criticize people’s “legs.”
Don’t wear loud hued leggings
Don’t cultivate a “bicycle face” (what the hell is that?)
Don’t refuse assistance up a hill
Don’t wear clothes that don’t fit (Still a good idea)
Don’t neglect a “light’s out” cry
Don’t wear jewellery while on a tour
Don’t race. Leave that to the scorchers
Don’t wear laced boots. They are tiresome (Still a good idea)
Don’t imagine everybody is looking at you
Don’t go to church in your bicycle costume (yeah... but hey, that's up to your church)
Don’t wear a garden party hat with bloomers
Don’t contest the right of way with cable cars (Still a good idea)
Don’t chew gum. Exercise your jaws in private
Don’t wear white kid gloves. Silk is the thing
Don’t ask, “What do you think of my bloomers?” (Still a good idea)
Don’t use bicycle slang. Leave that to the boys
Don’t go out after dark without a male escort
Don’t without a needle, thread and thimble
Don’t try to have every article of your attire “match”
Don’t let your golden hair be hanging down your back
Don’t allow dear little Fido to accompany you (Still a good idea)
Don’t scratch a match on the seat of your bloomers
Don’t discuss bloomers with every man you know (Still a good idea)
Don’t appear in public until you have learned to ride well
Don’t overdo things
Let cycling be a recreation, not a labor
Don’t ignore the laws of the road because you are a woman
Don’t try to ride in your brother’s clothes “to see how it feels”
Don’t scream if you meet a cow. If she sees you first, she will run
Don’t cultivate everything that is up to date because you ride a wheel
Don’t emulate your brother’s attitude if he rides parallel with the ground
Don’t undertake a long ride if you are not confident of performing it easily
Don’t appear to be up on “records” and “record smashing.” That is sporty.
