Long skirt frame/parts/tips?

Cheapest and eaiset solution: use a clothes peg to peg the skirt up out of the way. If teh rider is worried about flashing too much leg or her bloomers, she can pull on a pair of leggings or some shorts underneath.

A peg means you can ride any type of frame at any speed you like!

Out of the question! The bike is for a lady!
