I have multiple cameras. Obviously your primary camera goes on the helmet. Where on the helmet is up to you. I've always liked the chin mounted. I used on the side before and I didn't really like it. You're going to catch more than one side of than the other. Also, it's more obvious than you think, but I had mine on the left. So when I looked right to show something it wasn't getting as much as I had thought (since the GoPro is an action camera and better for upclose.) Again that's up to you. The second I move around a lot. On the bars or tank pointing at you always makes for some nice shots. I've mounted mine down low and caught my front wheel and the road. It makes it good when you need to cut and come back etc. It gets handy in editing. If something is getting boring you can cut to a different shot and cut back etc. I've put my session on friends bikes, down low up front, facing me, on the rear, and even on my wrist strap.
