No, really, bike naked:

One hundred cyclists of all ages and in various states of undress - some fully clothed, others naked - rode from Tarakohe to Pohara on Sunday for a cause they strongly believe in.

There was almost a carnival atmosphere at Golden Bay's third annual World Naked Bike Ride, as spectators lined part of the route, with many waving and cheering as the cyclists rode by.

Includes potentially NSFW picture, so beware!

Oh don't look at me man. I don't go anywhere without my SoopaSeat and UltraPants. My minimum bike ride tends to be 1 hour, and now that the weather's turning I tend to ride 4-6 times a week. With a schedule like that, saddle sores developed during a stunt like this would be a long-term discomfort!
