You won't be disappointed.
One tip. Buy a GoPro tripod adapter from Evilbay. They cost about £3 and will enable you to screw it onto a suction cup for better angling of locations on your bike. The one thing GoPro suck at is that stupid mounting foot thing they patented. Whilst it is genius, it has its limitations. I have the GoPro Hero 2 AND a Drift – both good but both excel over each other in different areas. The mounting being one of them.
I'd also get something simple like a cord from a camera that you can secure to your bike, and the camera. My GoPro came off the bike the other month and went bouncing down the road. Whilst it only minimally cracked the outer case, I was lucky I actually found it.
Just a couple of tips from someone who knows.
