most astonishing bike tricks I've seen... and this was 50 years ago, in heels, on stage. Not even Danny MacAskill can pull off these tricks

Lily Yokoi, the "Ballerina on the Golden Bicycle"

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.

abandoned limestone mine in Kentucky transformed into underground bike park... coolest thing you'll see all day

The complex includes about 12 miles of 45 trails marked by different technical skills and riding styles � and by features such as jumps and a cargo container that been integrated into a bike overpass.

 According to Louisville's Courier-Journal, the course was designed and built in about 10 weeks with a skid steer, a mini excavator, and a 950 loader by Joe Prisel and Jeff Perkins who have worked on more than 20 indoor and outdoor courses. The cavern was bought from a limestone mining company back in 1989, with the idea of opening a "high-security business park."

In 2004, driven by the desire to ride year-round, a carpenter named Ray Petro spent four months converting a 130,000-square-foot former rayon factory in Cleveland into the first indoor park in the country. The result, Ray�s MTB, was a vast playground filled with ramps, jumps, and roller-coaster-like pump tracks. �I wanted to make guys who are 30 feel like they�re 15 for a few hours a week,� says Petro.

 It worked. Ray�s was so successful that Petro opened a second location in Milwaukee in 2010, with its own street park, pump track, foam pit, and VIP lounge. Soon other frigid locales like Toronto, Pittsburgh, and Syracuse, New York, had indoor parks, too.

Louisville's Mega Cavern is a massive entertainment complex where you can ride zip lines, swing from aerial ropes, and take historic tram rides, in addition to partaking in other activities.

It's 60 degrees year-round. There are 12 miles of trails, and a four-hour pass is $24, an all day pass is $40. Bring your own bike, helmets are required.
