First time I have used the Muvi on the bike. Bought it for car track days and worked fine for that, but figured I could also mount it with a strap around the chin of the helmet, to keep it out of the wind blast. Seemed to work okay with a little variety provided by the 'ankle-cam'.
Jerky image was down mainly to a dodgy microSD card. Its just a test and not terribly exciting but seems to work okay.
