Is it worth upgrading to a bike of the same segment? / Yo Spark Questions Indus

I don’t think so, as Spark is a high capacity electric based scooter but rest of the companies are yet to have a model which can run up to a speed of 45 Kilometer per hour. So its setting a new trend, so no upgrade is available however you can upgrade to better mileage with reduced speed, they there are several options available which may be considered in hero electric, Avon, lectrix etc.
