A fat tire & a skinny tire & two others I loaned out
Not bad, what kind of camera are you running? Also, have you considered trying to put together some sort of chest mount? Might help with the shakiness. My personal favorite GoPro mount for biking is the chest mount, & it isn't a very complex design. Gives a good perspective view of the bike while maintaining good visibility of the landscape. It's all preference though, & I like that you can still see the handlebars just a little bit to give you some perspective of speed & depth. Oh & I don't know of any off hand, but you could probably find a free video editor with an anti-shake filter with a quick Google search.
