I wish I could find it on YT now but I cannot.

As everybody knows, Amsterdam is full of sex and full of bicycles and full of canals and full of other good things.

So a few years ago there was a splendid YT video about a girl who was riding a bicycle in Amsterdam (and the bicycles in Amsterdam are those prehistoric contraptions - not at all like high-tech multi-gear etc. sports bicycles), and, little by little, getting aroused.

At the end of the video, the girl comes - as far as I remember,

1) she had to stop by a utility pole and embrace the utility pole with her arms to keep herself steady for the climax (at the time of my watching the video in 2008, I did not realize that the utility pole has a phallic form, but now I do )

2) the automobile traffic around her stopped, too, to observe and wonder.

So, the morale is, bicycles can be quite sexual.
