I use a Kodak easy shot m552 14 mp5x zoom. bought it 2yrs age for $70.00. and it's still working.
small foot print very light wgt. 2.7b screen so I can view the progress of the of the video while riding.
it takes video and pics.
I mount on my bars while video recording( 720hd ) my local bike paths .
the camera lock up due to shocks from going over tree roots popping up the path.
my hybrid doesn't have any front shock.
I fixed this by reducing the front tire. drop down from 80 to 50 psi.
