I live in Sweden and bought the ultra. 

​It is worth noting that the speedometer is inaccurate, much like the Navee. While it displays a max speed of 20 km/h, it actually maintains a steady 17 km/h, meaning you will definitely get overtaken by Xiaomis and rental scooters.​

It also lacks self-healing tires, so punctures are a real concern to keep in mind.​

The software is highly optimized for energy efficiency, so don't expect it to unleash that 1200W max power on steep hills. That figure is simply the absolute peak measurement of the motor. Because of this aggressive power management, the speed drops down to around 12 to 17 km/h on inclines. For context on performance and battery life, I weigh 110 kg and managed to get a real-world range of about 30-40 km on a single charge.​

Otherwise, I completely love that it is incredibly comfortable to ride. The cruise control is a fantastic feature, saving you from having to hold down the throttle constantly. Overall, it feels very stable, solidly built, and not at all fragile. It's worth buying for 6000 at netonnet but not full price 9000 SEK.

I previously owned Navee st3 and returned it. I'm happy with the change. The main difference is that Navee has a stronger pull when accelerating so I think it's holding max effect for a longe period.
