Has anyone looked into an electric motor assist? I saw an old gm car with an LS? engine swap and a big electric motor mounted like an alternator with a wide cogged supercharger like belt going to the crank pulley. It also was a heavy car with a ton of batteries.
I wonder if something similar but smaller scale would be worth looking into? Mount a small electric motor and have it assist the crank at cruising speeds? Might work good for putzing around town at 30-40 mph where once you're up to speed it doesn't take much power to keep moving.
