First of all, I must say that I was pleasantly surprised by the scooter. I'll start with the range, which I tested today. On a very hilly route of 6+6 km (there and back), so 12km in total, the battery dropped by 2 bars (out of a total of 5). That was -40% of the battery. At home, it showed 60% remaining energy. I was riding in sport mode, but not full throttle all the time. On the flat, for example, 20-22km/h, sometimes at max speed. At this rate of consumption, the scooter should manage about 24km on 80% of the battery. It's a far cry from what the manufacturer states, but they tested it in D mode, which has its top speed limited to 15km/h, and that feels really slow. (20km/h would be ideal). If the max speed for D mode could be set in the app, it would be great, but unfortunately, it can't. :-( You can only set the level of recuperation. On the handlebars, you can change the mode (walk, D, S) and switch the lights on and off. When you switch the lights on, the display dims slightly (so it doesn't dazzle you at night), but it's still visible even in bright sunshine.
As for comfort, it's not too bad, you can even ride it around town where there are potholes in the road. The front suspension works quite well. I use the recuperation on the lowest level, where the scooter brakes just enough on steeper descents and it's not necessary to hold the throttle. The other levels are already too strong. Moreover, if you lightly press the front brake while riding, the motor starts to recuperate more and more, very quickly and surprisingly strongly, so you can stop just with the recuperation.
If the battery is fully charged, the recuperation is deactivated - so the battery doesn't overcharge. You should bear this in mind, because it has a negative effect on braking. As for the motor power, with my 75kg, the scooter still does 20-25km/h. On bigger inclines, it's about 18-19km/h, and on the steepest ones I've ridden (Smiřických street in Říčany), the speed dropped to 15-16km/h. The tyres are inflated to high pressures, according to the manufacturer 50-55 PSI, which is about 3.4-3.8 Bar (atmospheres). Definitely inflate them so you don't reduce your range. 😉
Charging is slow and no fast mode is available. A full charge takes about 8-9 hours. And the charger gets quite hot. During charging, you can't select a max charge level to preserve the batteries; it charges to 100% and then switches off. If you live on a hill, just unplug the charger earlier, because you won't charge anything into a 100% full battery while riding - recuperation won't be active. Overall: yes, the scooter doesn't have the range the manufacturer promises (45km), but I didn't expect that. A realistic and brisk 30km is sufficient. p.s.: the scooter is not for carrying around, 20kg is already a lot.
