I bought one of these cameras. http://cycliq.com/product/fly6 It arrived last week. It took only three days to arrive all the way from Australia and somehow managed to escape the notice of customs so there was no duty to pay. It certainly a bit on the pricey side – but in the last four years I have had two occasions where I have been riding in a narrow road and have been hooted by impatient drivers and eventually deliberately rear-ended by them. One of them was a taxi driver who reversed away when I got my phone out and try to take his picture. The second one was a driving instructor who then went on to threaten to hit me and laughed when I tried to call the police. The police arrived and refused to do anything and then simply had a chat and shared cigarettes with the driving instructor. This was in Paris by the way. It is these experiences which eventually prompted me to splash out on this rear facing camera because if this kind of thing ever happens to me again, I intend to make very serious trouble. The unit is like a large standard light. It is fairly heavy. The camera lens does not draw very much attention and no one that I regularly ride with has yet realised what it is. Although the unit itself is quite sophisticated, I would say that the firmware that comes with it is rather lumpy and there seem to be anomalies which are a bit of a nuisance although they don't interrupt the functionality of the light or the camera. For instance, my unit doesn't beep as it should do in order to signify the level of battery charge and also, the charging light doesn't always come on even though it is charging. Another example of rudimentary implementation is that in order to set the time and date on the camera, you have to access file in its root directory and edit a config.txt file. Still, once all that is done then it seems to work excellently. The video quality is extremely good and it overlays the time and date on top of the video image. Customer service from Fly6 – Cycliq – is extremely good so far as they respond well and in a very detailed fashion to my queries. They also don't seem to be too defensive about admitting that there might be a glitch in the firmware. This is refreshingly honest and it gives me confidence. The unit comes with two mounting kits so you are able to have mounting brackets on two bicycles. I would certainly recommend this item – although as I have said, it is sold at a fairly luxury price. However, it seems to be the only thing of its type on the market. Maybe if they start selling volume or if they get some competition, then the price will go down. I understand that they will be doing a front facing camera and that it will be available in February. I think that I am likely to get one.
