Pros: It's a powerful machine. It's solid. It can carry my 90kg with elegance. It's FUN! I am a motorcyclist and I know a thing or two about 2 wheels fun. This is fun! I rode it for the past 2 weeks almost eclusively. Hillclimbing is IMPRESSIVE! I took it yo a spin in the hills (paved road). I rode it for 20 km uphill in dual mode power 3, and it did the job. That was a 1000 meter elevation gain with some 25% slope for 1 km at some point. Range is decent: 40 km of spirited city ride or moderate dirt/rock flat or 20 km spirited uphill paved. Nowhere near the 80 km, not even with my 40 kg kid.
Cons: suspension is at most adequate for road. For offroading it's too harsh. A steering damper is beneficial. The floor/batery lid is not closing snugly and it clunks. The suspension clunks as there's play in the upper eye/bolt. Acceleration is abrupt even in PA setting 0001. I cannot hold an intermediary speed without juttering its either full throttle or no throttle. Very little modulation. Because the lid is not closing properly, dust gets to the battery. I bet water will get there too if left in the rain
It's a 4 star minus review because it's an expensive scooter in the kukirin range.
If mostly used on flat and paved city and suburb commuting and moving around, buy the G4. It's more value for the money.
