Suggest Scooty for my sister for her office travel

My sister is a working girl and she need a new scooter to go to work . Her daily up - down is around 25 km . She is 5"3' and not very healthy, we can say she is light and hence she need a light vehicle.

Her need is that ride should be easy , comfortable and mileage must be good as other than office, she may also going to places for regular things like market and stuff. She likes Honda Activa but says it is bulky and big so now my task is to choose a suitable rider for her.

Guide me friends because I need to finalize it in 3-4 days or sooner. I don't want to get her something which she regret later.

Thanks

I would suggest Suzuki Lets or also can choose TVS Wego.

But if she want something which looks and feels light then TVS Scooty PepT is very nice and now very refined.
