I want to purchase an electric scooter. My daily running is around 80 km and sometimes more. I already purchased an OLA electric scooter 2 years back, but I’m not satisfied due to poor performance and several issues - the vehicle stopped working and had repeated MCU and other problems. Kindly suggest the best electric scooter for my daily use, with an average running of around 80 km.

Since your daily running is quite high, you will need to get an electric scooter with a 3.5kWh battery pack or more. For your needs, we'd advise you to pick between the Bajaj Chetak 35 models, TVS iQube 3.5kWh variants and Ather Rizta 3.7 duo. All three are proven models and come from reputed companies with a decent reputation for aftersales so you should, by and large, not have a similar experience as you did with your previous Ola Electric scooter. 

Picking between the three will boil down to which one you find the most manageable and which company has a sales and service touchpoint near you. Take a test ride of all three to make a more informed decision.
