In some cases, smaller is better. I had a Harley Davidson in 2000. I sold it and bought a Kymco GTI 300i in 2012. Then I bought a X-Town 300i ABS in 2021. Last January I traded down to a People S 150i ABS. In my case, the older I got, the smaller I went. I'm 80 now and love my People. It's light weight, easy to maneuver, and has plenty of pep for me. I think the size of the scooter should be determined by your comfort level riding it. As long as you're comfortable and enjoying the ride go for it whatever the size may be.
