I don't, but DH has a couple (not for biking). I wouldn't use it while riding, personally. It's plenty sturdy for stationary applications, but really not meant to keep a camera from falling off a moving, vibrating object. There are many solid mounts for attaching cameras to motorcycles - it would only take a little shimming to adapt them for bicycles.
ETA: this looks easy, solid and extremely cheap...
