Is it possible add a torque converter to store energy centrifugally? Something like the flat round weights that weight lifters use and gear it so one can stay in drive gear and gear up the spin rate on the weight. Then when you go up a hill, gear down the converter to add force to the main drive. It would be neat if somehow this could be integrated into the front wheel to add weight to the front. I do not know engineering. This is just an idea I have been wondering about for a long time. Don’t even know if it could be worked out or if it is feasible.
