i want to put my engine in the same chain system as the original crank. the reason for this is so that i can use the gears in the back sprockets as sort of a transmission to give me a full width of rpms. can i jackshaft this or do something to stop my pedals from moving when i start the engine. i dont want to lose a leg in the action lol i was thinking of a cool design where the crank sprocket is like a bearing assembly and can be disengaged and lay freely while the part with the teeth only moves. but im no genius so i never went thru with it. the point is, i want to use the gears in the back as a sort of transmission for my engine while still being able to have my pedals from moving. <awkwardly worded>
