Really love the kugoo m4 and the speed you get on 3rd gear. My only issue is the sterdiness of the frame when travelling on uneven surfaces. There are times that it feels the handle bars fork is going to snap. This may be due to the extendable handle bars so not much support available. Acceleration takes a little to get used too as it's in an uncomfortbale position compared to the xiamoi. Albeit it is a very fast quick scooter and will be the talk of the town.
I bought kugoo m4 last week it is very comfortable when use it with saddle and also it is really beast on 3.mode but be careful do not use without helmet. I recommended this scooter absolutely worth it
