I have had it for a month. Overall, it's very good, but I don't have experience with other scooters to compare it to.
I weigh 60 kilograms (I don't know if the weight of the rider makes a difference in battery life, but I mention it) and I use it to commute to work, which is an easy route - maybe a short ride as well.
It is a bit heavy, but it's understandable since it is sturdy and well-built - so you get a little workout for your arms if you need to carry it upstairs without an elevator. However, it folds up perfectly for transportation.
The battery does indeed last for 30 kilometers (in eco mode), but the "strange" thing is that the battery indicator on the screen only has 5 bars. Once it reached the last bar, it started to slow down on its own until it completely stopped. Luckily, I was close to home. So, when it reaches 2 bars, you should know that it will soon need to be charged.
It charges in a maximum of 5 to 6 hours.
If you don't have it in eco mode, which reaches up to 16 kilometers and maintains a steady speed, but instead have it in speed mode, which has a top speed of 25 kilometers, the battery drains a little faster and it covers slightly less than 30 kilometers.
The brakes are good. I haven't adjusted them, but I've heard that you can adjust them like you would on a bicycle if you don't like them. Generally, they work better if you press-release-press-release, but the scooter will never come to a sudden stop.
The suspension is quite stiff, so you feel all the vibrations on the road - I don't even dare to try it on bumpy sidewalks - on the road, it obviously has no issues, but I avoid potholes or reduce speed - I assume it will gradually soften over time.
It has very nice lights at night!
If anything changes, I will come back to update
