I've ordered a Mobius action camera to mount on my bike, so I've been watching a lot of videos about the different ways to mount cameras. The one I like the best is a pole mount behind the rider, known as a 3rd person POV (point of view). Here's a search showing several of these and one about how a guy (Colin M.) made his mount.
Here's the bracket that Colin M used: http://www.x8drums.com/Gibraltar-Pea...-p/sc-pugc.htm
Here he explains how he used the bracket:
You don't necessarily have to buy a carbon-fiber pole like he did. An aluminum tube or even a wooden push-broom replacement handle would work. I'm going to try it out with 3/4" PVC conduit that has a flared end for the fitting of the next piece without any separate coupling. I found a seatpost clamp that exactly fits around the stretched end. I'll make a slit in the outer tube (terminated with a round hole for stress relief) so the extra seatpost clamp can compress the outer tube around the inner one to hold securely. That way, I'll have a 2-piece pole that can be taken apart quickly and stored in a pannier or backpack or on the rear rack when not in use. PVC may be too flexible and therefore bouncy. I'll see. Also, he mentions using a piece of rubber or cloth to keep the clamp from scratching the seatpost. In other projects, I found that black friction tape is the best because it is slightly sticky, made of rubber impregnated cloth that doesn't ooze or stretch like vinyl electrical tape. Hardware stores sell it. It's not vinyl electrical tape, but something different. The friction tape keeps the clamp from slipping around the seatpost.
This POV lets you see the rider and his immediate surroundings as well as the scenery.
Watch a little of this example:
I like that the video shows what the rider is doing, so you get a sense of the effort and that it's really a bike ride video, not a motorcycle or car or whatever. The main annoyance with it though is that the bike rocks side to side when you're pedaling hard or standing, and this causes the horizon to rock. You don't notice this rocking horizon when you're the rider on the bike because your head tilts and actually your eyeballs can rotate to maintain a horizontal horizon. I'm working on a swiveling bracket for a pole mount so the camera can remain more upright in spite of the rocking. If I figure one out, I'll post a sample video and a how-to instruction.
Compare that video with this one taken from a handlebar position:
And here are more points of view:
There are other YouTube videos that demonstrate comparisons of the various mounting positions: helmet, handlebar, chest, bike frame, telescoping pole on handlebar mount, 3rd person backpack, and 3rd person pole. The handlebar has a lot of vibration and side-to-side (left-right turning) motion at times, and you often don't see any of the bike in the picture. The helmet suffers from showing where you're looking rather than where you're going. Chest mount has problem that its view is affected by your riding position which changes from time to time during a ride (leaned way forward, more upright, depending on hand position) and the picture is framed by two big arms. Bike frame mount is not too bad, but has more vibration than chest mount.
