Billionaire Bhavish Aggarwal shared maths behind electric two-wheelers, explaining how e-bikes are cheaper than petrol ones. ICE two-wheelers have 50kmpl mileage and run for ₹2/km while e-bikes have 30Wh/km mileage and cost ₹0.2/km to run, Aggarwal claimed. A Community Note on his X post noted e-bikes cost more upfront and their total ownership cost is higher even after 5-6 years.
