have you seen them?what's all this disgust about male genitals

But seriously, I think this is a sexism issue. I bet they aren't kicking out women in yoga pants, or strappy summer dresses, or thin t-shirts etc etc. I think the "men's bodies are disgusting" meme is a nasty, repressive one. I think the sexism is mostly still coming from heterosexual men, the same pressure on older or fatter women to cover up. Men like seeing bodies they fancy, and don't like seeing ones they don't.
(though after a quick google, I bet this is just a publicity stunt. They probably don't get many cyclists, so losing the custom of a few to get nationwide or international publicity is probably a good deal. It's pub set picturesquely in the middle of a large carpark. )
