1. strictly in city use, even scooty pep+ will do fine
2. for normal size scooter I'd go with TVS wego disc brake version. Body Balance thingy is not just a marketing gimmick, it does work. ride Wego at single digit speed and you will know. It's so effortless, esp when compared to activa.
for me safety first, where Wego scores high with it's 12" wheels, tubeless tyres, Body Balance
DO test ride it before deciding.
avoid Activa, stone age front suspension, really poor braking, poor straight line stability under hard braking.
