A little while ago I decided to design and build myself a bicycle out of carbon fibre. As I began working on the design an idea for a cable driven bike struck me, so I began to put my thoughts on Kpov. It's pretty tedious work, so I took a break and tossed some colour on it and threw it in a half-assed landscape. It's far from complete (I haven't rendered the drive setup or brake system for it), but I think it captures the essence of the design. Anyhow, any feedback would be appreciated.

I forgot to mention the whole point of my bike in the description. When pedaling a bike, the amount of force you can exert is less than or equal to your body weight, and even then it's only fully realized when the direction of force is tangent to the crank and passing through your hips. On this bike you lay on the seat with your legs behind you clipped to pedals on a carriage running the length of the bar extending rearward from the seat. The carriage is linked by cables and pulleys to the rear hub, which contains the real heart of my idea. I purposely obscured the rear hub a bit, because I haven't built a prototype, and I don't want everyone to see exactly how it works yet. This setup should allow far greater force to be applied to the drive system resulting in a significant increase in speed. One other happy side-effect is that laying prone on the bike should lower the drag coefficient considerably. One last thing, I named it concerto 'cause I consider it a stringed instrument.

Hope that explains the bike a bit.
