The handlebar mount was custom made for the DVS550 by Rigidmount. The Rigidmount site is a good one to check out for reviews of affordable cameras that are useful for bicycle-mounted applications.

Here is some example footage from the camera in low light conditions. I took this back in June.
I have tested this camera mounted on the bars of my Bike Friday New World Tourist. It has so far proved to be weatherproof, and the custom mount has proved to be rigid, as claimed with very little blur from vibrations. The quality is good enough to capture vehicle plates in good conditions, with good light and no rain. The LCD screen is very handy as you can see exactly where the camera is pointed, and whether it is recording or not.
Spare/replacement batteries are cheap and battery life is OK, I have been consistently getting 2 hours worth of recording out of my original battery (the spares have been ordered and are yet to be tested).
The sound is pretty good for a weatherproof camera too. It picks up some wind noise but it also picks up my voice when I talk to it. It comes with a carabiner which can be used as a safety precaution if the primary mount fails. I have mine attached to a cable tie that I wrapped around my stem.
The battery can rattle around in the body of the camera due to less than stellar manufacturing tolerances – this can be fixed with a little electrical tape. The method is detailed on the Rigidmount website.
The still photos are not great by modern camera standards.
The camera takes up quite a lot of space on the bars
I would recommend this camera for commuters who wish to record their commutes for any reason. It is good for capturing recreational road rides as well. It may not be the best for mountain bikers with a lot of inconsistent light, as the camera is a bit slow to compensate for changing light conditions.
