Duct tape.
Lots of it.
I was worried about those when I first got them but I've never heard of them letting go. Just make sure the camera part snaps into place.
Two sided adhesive tape, think I can trust it? Or should I tie a line to it too?
Thanks. Camera was free anyway. Came with waterproof case that had a scuffed up lens which I just took off.
It's easy to find parts like a new case or just a replacement lens on the internet. You can get different backs that allow sound
I've found that mounting it to the bike can cause engine vibration to distort the picture, like heat waves on a hot day.
I am cheap. I took the back off and used duct tape to hold it in.
