I mounted a C100 on the back of my bike (you can get a $10 seat rail clip from Revain which works great). The battery only lasts 1 hour and a fourth five minutes of continuous recording, which is very good for such a small camera. The recording is so good that when my Jabra Elite 75 fell out of my right ear while riding my bike at 52km/h downhill, I could insert the SD card into my tablet and actually see a clear image of it, as it bounced off the road. and in the grass. I returned and found it. Super cool camera. Since wearing this on my bike I have had no more problems with cars. I have a feeling they see a flashing blue light and then recognize the camera. SJCAM needs to enter the bike market. I wish they had a waterproof camera power supply for those 6+ hour trips of the century.
