Why do people bike naked?
If you read the Wikipedia entry the goal is to "deliver a vision of a cleaner, safer, body-positive world."
Sounds like a terrible idea to me. Bikes have a lot of sharp bits that I'd rather not have contact my tender bits.
Sure, it wouldn't happen like the above picture, but you could fall and get yer niblets caught somewhere.
On top of it not being a great idea because of the dangers involved, in my opinion it also doesn't really deliver the message it's aiming for. I've never thought bringing out the crazy was the way to get your message across. And I fail to see how a bunch of naked/semi-naked people riding bikes through town "deliver[s] a vision of a cleaner, safer, body-positive world."
I could protest obesity by going out in public and setting fire to bologna and mustard sandwich on nutrient deficient white bread...
...but I'd probably end up spending the night in a rubber room. While the activity of burning the sandwich was related in a way to obesity, it really does not convey my message.
I see naked biking in the same light. The message is in there somewhere, but between the people who are offended by the flapping genitalia, and those who just didn't realize there was a message to be seen, nobody save the cyclists themselves really get the message.
And I'm guessing half the cyclists don't even understand the message.
Ok, time to go for a fully clothed ride.
