No matter how much you 'save' on gasoline it will take a long time to break even.
EV two-wheeler is now becoming craze here, but unless someone rides that much, it actually won't break even ever. Some buy it just for craze, but I am good with my old one, as I drive very less. The other down side is to have it regularly charged, and I believe, if not used and charged continuously, battery life will also be impacted ?
EV two wheeler, yes I have seen them. Also something called "toto" which is a battery operated auto rickshaw, very popular around Kolkata. It's probably fine for commercial use but for personal use won't be break even.
Yes battery life will be impacted as you said.
