This is a human powered vehicle that I have been designing (mostly in my head) for the past 5 or so years. A Provisional Patent Application has been filed with the US Patent and Trademark Office and now thanks to my dads' help I can say it is now Patent Pending. I love coming up with new ideas. I spend a lot of my time thinking of ways to improve human powered vehicles, energy storage systems, etc.. These drawings were done to US patent Office standards with Autocad in 3D I am now learning how to use Solidworks to do my drawings and virtual prototyping. Also, these drawings are not at all the final design. They represent the concept only for the purpose of the patent application. And to help you in your grok process.
The way this vehicle works is by moving your legs back and forth. A cable wraps around the rear hub that is attached at the forward end to the frame or some other relatively fixed location on the vehicle... So when you push your leg back, the cable unravels and spins the wheel forward. 
If you ever had a gyroscope as a kid you can see how similar this kind of principle works. The rear wheels are like gyroscopes being pulled while the string is held in a fixed position. Figure 1A is an isometric view, 1B is the front view, 1C is the side view, 1D is the top view, 1E is a detailed sketch of the rear.

James,
I cannot support this excellent project with dollars at this point. You should check the link I am posting to CAT the Center for Appropriate Transportation here in Eugene. They have an entire shop dedicated to creating human powered vehicles. I take kids there for field trips. They might be an excellent resource for your cool idea. http://www.catoregon.org/
James,
Interesting concept. Might I suggest moving the footpads forward slightly and attaching them with a hinge at the front? A properly placed stop under each pedal would allow them to rest more-or-less flat when coasting; when driving, the rider would be able to pivot his/her feet, much like in cross-country skiing.
Good luck.
Just wanted to say that is a cool looking scooter-bike idea. Good luck with it as it looks like it could be fun and a good workout!
