Kinda like what patriot was saying (Thanks for the idea

), put dual double rings on the bike, one on each side, and have dual cassettes, one for the front wheel and one for the rear!
Edit: oh yeah, ya gotta be able to steer!!!!
Bicycling Magazine had a bike a few years ago where the front wheel was driven by a flexible shaft. There are motorcycles where the front wheel is driven by a hydraulic system.
