I would look to Specialized and Trek for something as you've done. Their bikes are the lightest FME. Giant and many of the other OEM's don't post weights for good reason. Most are too heavy, and the no-name brands are even heavier, although some are good deals and function well for their cost. You might scan electricbikereview & electricbikereport, which test numerous models. The other option is DIY, but much more suited to experienced tinkerers.
