I just picked up an Apeman A80 from Amazon and mounted it on my handlebars to test the gyro and get an idea of image quality. (Filmed in 1080, but converted to 720 for YouTube.)
Audio was recorded using an Olympus digital recorder with a mic in the pocket of the pack on the back of the bike. The camera did pick up decent audio without much wind noise while in the waterproof case.
