This is it - $8 for a mini tripod and the reflector bracket off a bicycle! Remove the head off the tripod, bolt it to the reflector bracket and mount the whole thing toward the center of your handlebars. I'm sure there would be less vibration if the bracket were metal as opposed to plastic. I don't remember who it was that had a camera mounted to a piece of metal strapped to their helmet, but you might consider going with this type of a mount on your helmet just to class your rig up a little. I laugh, but you did get pretty decent video off that thing. By the way, the Vivitar mini tripod had that best ball and lock, so that's what I'm using here.
