I saw a similar camera mount on Bike Forums. The gentleman had also posted pictures taken using a camera mounted there. It could also be rotated to take pictures of side views too. And pictures were very still, no shakes.
Have you tried out your set up?
Yes have tested it once but the Brake levers at the front contribute to the noise, this setup can be adjusted fr angle change of the camera fr up and down angle ...but have to add a rotator to the setup fr side viewing...good sugesstion ...will try out and post the new setup
