Hahahahaha! Oh, that it were true! My bike irritates me rather than getting me all hot and bothered. Maybe I need to try the seat the mullah was experimenting with! Maybe he got all horny when he rode it, but of course he won't forbid men since they need to GO places, unlike we women folk who need do nothing but while away our time at home waiting to pleasure our husbands whenever they please. Ahhhh, the good life!
Actually, I think some say it is haram because people might actually look at her, a woman riding a bike being such an unusual sight on a bike in the Muslim world. (Very immodest.) Besides, her bottom's shape would be slightly exposed. Oh my!!! Better ban backless chairs for women as well. (Eyes roll.)
