I've had luck using a narrow punch with a sharp (or sharpened) tip. Hammer the punch in a circular pattern to unscrew the bolt. The sharpened end can do a good job biting into the sheared bolt. (This is a good first resort method before trying an ez out). Spray with WD40 or soak down with a very light oil to make the extraction as smooth as possible.
Worth a try and it's non invasive so no risk of damage to the bike itself.
