I got my own GoPro Hero 3 Black + back in July 2014 and, so far, I think I have only really been scratching the surface of what it can do. I have the handlebar mount and a couple of the standard adhesive mounts which have given me pretty good results so far but the choice of shots have been fairly limited. The first real film I made with it was during my recent Paris to Hayling ride. (Basically I rode 375 miles or 580 kms from Hayling Island in the UK to Versailles in France and then back to Hayling.)

Over the last couple of days I have been looking at some interesting films on Gopro's website. One in particular was about a group of female motorcyclists. https://www.youtube.com/watch?v=__FmZWlsOf0
Although not exactly bicycles, the shots they were getting on their motorbikes were much more like the ones I had in mind when I bought my GoPro. From the looks of it, they appear to be using things like chest harnesses, helmet mounts and various imaginative mounts all over their bikes and then just shot the hell out of it.
