Has anyone made cullotes? Are they easy?

Can i ride a bike in them?

If I start with a full circle skirt, could a cut in a crotch or isbthere a better way?

I second Helen's closet Winslow culottes. Super quick and easy to make, I've made several pairs and love them, I've even been stopped and asked where they're from. There's a pattern hack on their website to put in an elasticated back instead of a zip which I prefer.
