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

I use a head strapped one, as it's much stabler and easier to control, I only have use the handlebar mount only so don't have much to show.

If you can get someone in america to get you a go pro3 you'll save like £100 ish on the price here

Or Europe, like Spain, save you something like £40-60.
