I need some help figuring out the title of a book I read years ago.  It is a cyberpunk type of novel, one of the main characters is a teen-aged(?) girl living with her grandfather(?) in a shantytown built on the Golden Gate bridge.  The few other bits I can remember: she rides a bike made of compressed paper with an electrifying anti-theft device on it.

Does this sound familiar to anyone?

Cyberpunk set in San Francisco?  Three names pop into my head.  Pat Murphy (but it would have to be a short story as it isn't one of her novels.)  Lisa Mason.  Richard Kadrey's first two books. 

Just checked those three authors via Google and Amazon.  Definitely not Pat Murphy or Lisa Mason.  Richard Kadrey's "Metrophage" seems very familiar, but I don't think that's it, either.  (Thanks for the tips on the authors, though -- I'll be checking them out!)

Kadrey apparently posted "Metrophage" online for all to enjoy...  http://www.voidspace.org.uk/cyberpunk/metrophage.shtml

Mystery solved!

For anyone interested, I just received a PM (don't know why they didn't post here...) -- the book is "Virtual Light" by William Gibson.

Can't believe I couldn't remember that.
