Cycle Cameras / Helmet Cams (GoPro, Drift, Veho, Contour, Fly6, Fly12, SJCAM, Apeman, 1080p, etc.)

But with a smart phone you'll end up with no battery life, no storage, and if there is any rain your phone may die, and if it gets knocked a lot it may break.

A phone costs more than a dedicated camera, which will be showerproof, have it's own storage, have a lens with a wide field of view to catch all the action, have a larger lens so it works in dimmer light... the list goes on.

I agree with a lot of what you say there, though I am not looking to use the camera for documenting my commute. I don't actually want the wide angle as it is usually very distorted, and I don't need a helmet mount option. I just want some footage to edit and then produce a soundtrack for. I admit most are not going to be in the same boat as me.

I think I am willing to drop £25 on the mount and try it. Thanks for your reviews though, it all helps.
