I don't have reflectors on my road bike or my Sirrus because those aren't ridden at night. The other utility-type bikes have them because they are ridden for practical purposes as well as recreation. That means night riding. I removed the front white reflector from a few of them though. Only the trikes still have that one. I also replaced the rear red reflector on a couple bikes with a Cateye Reflex taillight that has a built-in reflector.
