Tried it on my helmet, seemed ok in a test at home, trouble is that at speed I seem to lean forward and end up with a shot of the road and not whats ahead, love to get some good engine sound, but again wind noise, suppose at least with the sidecar I have more mounting options, just have to get a good angle, and again with it on there it's a tab bumpy with it empty. I don't have a gopro, too expensive, but got one that does take a good HD video to a memory card, another problem is that if I lift the chair at speed the camera levels the shot so you don't get the image of the chair up at an angle, have to look into the menu see if I can turn that off, darn another excuse to get out for a ride
