There are extraction tools that look very much like a drill bit that spirals the wrong way. You also need a drill that has a reverse gear.............. The problem now is getting the remaining (theaded end) out (it does not go all the way through but bolts into the top tube).
Any suggestions on how to do that?

Thanks. I do have an extraction tool actually.There are extraction tools that look very much like a drill bit that spirals the wrong way. You also need a drill that has a reverse gear.
First thing is to drill a small pilot hole with a conventional drill bit. That will give the extraction tool something to bit on quickly, rather than skittering about on the fractured surface (you might have that problem with your pilot drill, so try a centre punch first to make a start).
I know you said the bolt does not go all the way through, but can you actually see the other end of it? If so, you may be lucky. Just drill through from the other end with a conventional drill bit and the drill set in the normal clock wise direction. If you are lucky, the torque from the drill will unwind the broken bolt.
Agreed but there is something you could try first. Remove the bottom shock fixing so that any pressure on the remains of the bolt is alleviated. As you move the shock now through the available amount of travel does the bolt stub remain still or does it rotate with the shock.There are extraction tools that look very much like a drill bit that spirals the wrong way.
