Done it twice while out on the road. Once by myself and once with a VERY close buddy.

Pulled the shorts down just enough, handlebar in one hand, other thing in the other, turned enough to the side, and let 'er flow. Had to go slow, but it works. I wouldn't suggest this method as a normal means to an end, but it's tried and true.

No solution but find a restroom...gas station, QSR...bushes..

There is a women's "Tour de France" and you can see when it is time they all go in masses looking for a place..one after the other. It is funny because during that period of time nobody attacks to break away from the group...it is a sport's code.

Take it from an old timer cyclist.
