hi'i just bought a new samsung camera.....any good ideas on a decent handlebar mount for it?
any help will be appreciated

Minoura makes a robust looking one. I own the clamps part, which adjust for different diameters, and that much is excellent, with quick-release also. The camera mount has a stainless platform with a cork bed and 1/4" bolt. I don't own and haven't used the latter.

I recommend helmet or chest mount over a handlebar mount. From my experience I had with handle bar mount it very shaky and bumps on the road made it very hard to watch. or maybe my mount was cheap lol. My2 cent

I'm going to agree with the helmet or chest mount. Even on fairly smooth pavement, the handlebars are vibrating more than most cameras can compensate for, and you have to turn the bike to capture the view to either side, which isn't always convenient.

I'm modifying a spare helmet for just this purpose, and for the exact reasons you've seen, here. The video is very hard to watch when it's shaking and bouncing like it did on the handlebars.
