has anyone built a bike that allows for the eng to run the bike so that you have like 18 spds w/ the eng using the derailors and such. I'm interested in building a superlight "dirtbike" which would be capable on steep inclines. I know the gears on a bike may not handle much torq, but it would be so versital w/ the engine. what do people think...new member btw
