Just bought a Miggo Splat flexible tripod mount for a GoPro.
I initially bought this so I could attach my GoPro to a tripod, however the flexible tripod is fare more, well adaptable.
You can use it like a handle or wrap it around handlebars, rocks, tree branches or even your willy.
I got mine from a camera shop in Chester but Amazon sell them too. You can even get bigger tripods that will take dSLR's.
