[Rickbus]

Hello,

As per my title thread you can tell i am a complete novice when it comes to bikes, anyways my gears / chain are stuck on the biggest front and biggest back and wont do anything no matter what gears i shift too.

Sorry further more to that my gear cables are still stiff and haven't snapped or anything, i just think my chain is at its maximum size and i dunno how to make it shift.

From the looks at the rear derailler it can be a couple things. It really does look like it is not aligned properly. There are a few things I would suggest but I am going to let one of the more experienced guys take on this one.

The chain is to short! You will have to add a couple of links.

See Alex's video:-

Initially move the back wheel forward as far as it will safely go to get you away. (Or move the wheel back and don't use the big ring.)
But then add the chain links as soon as possible and move wheel back.

And don't use this gear combination! One should never use the extreme combinations (small - small or large - large) as it is not nice for the chain to run diagonally: at the points where it leaves the chain ring and the sprockets it is bent quite sharply.
