I have been cycling around town in kilts (second-hand or home-made) for some years now and never found it inconvenient, even when it’s windy. I wouldn’t want to go out cross-country in a heavy kilt, especially in summer, and for a while I continued using lycra shorts for longer outiongs. Now, however, I have taken to wearing a short unbifurcated garment made from a pair of cotton trousers, and find this much more cool and comfortable.
As Bear said, it’s a way of combining two favourite things.

Since I no longer wear trousers or shorts walking, I see no reason to give up my kilts for cycling, but I’d better add, before any of the really keen cyclists retort that I’m wrong, that I’m not an energetic sports fiend, just a regular urban cyclist, who likes to have a few outings into the country when the weather is fine. There may well be reasons for not crossing the Alps in a kilt on two wheels, but that is not my aim in life.

I have not yet found myself in a situation where a was sorry to be unbifurcated.
