You are probably aware, but it is not a bad idea to purchase some of the mounts etc for these bike cams separately. That maybe a bit of extra trouble, but if you have the time, you can do some savvy purchasing. There are a lot of small guys in the market place with much of the equipment you could require.
For example the JVC camera we are talking about here JVC ADIXXION Action Camera GC-XA1
The JVC web site under accessories, lists the handle bar holder at $ 39-00. Here it is side by side with that sold by Jaycar who are every where and sell it for $6.95. It is identical, same push button release, same plastic covered tightening screw, the lot.
And they can't understand why some people buy off the internet. And Jaycar is a walk in store. So if you can wait........
Similar things can be bought for the go pro hero or any other cam.
