Hey Sabrina
I am very happy with the acceleration. The throttle can be pressed down continuously, and it is possible to accelerate more or less. The Segway G30D II has 3 different modes. Sport, D and Eco. In Sport mode, it accelerates quite quickly and especially when the road is a bit bumpy, it is difficult to accelerate less quickly, simply because the thumb trembles due to the vibration. On the other hand, you can travel quickly.
In Eco mode, the scooter travels a maximum of 15 km/h and accelerates very slowly. This mode is therefore very suitable for keeping up with pedestrians/adapting to their speed. Mode D is something in between.

The G30D has 2 brakes. The rear brake cannot be operated by the driver, but is applied as soon as the driver stops accelerating. This recharges the battery. In the app, you can set how strong this feedback brake is. Personally, I always have it on maximum, so the battery is charged more and the 2 brake (front) wears less. However, you should simply try this out on a straight stretch of road to see which level you feel most comfortable with. The front brake is a normal drum brake, but well designed so that the wheel does not lock and slip when braking hard.

Personally, I find the G30D II the best scooter I have ever ridden. The only disadvantage is that it is very heavy. On the other hand, it has a very long range and the sophisticated battery management software makes optimum use of it. It also accelerates really well when you get up to speed and hardly loses any speed.

Another important thing when buying: When downloading the Segway app, a software update for the scooter is suggested. When you install this, the latest German road traffic regulations are implemented - i.e. the scooter no longer has cruise control, the rear light brake no longer flashes and you can no longer access the scooter with external apps (if you want to). Therefore, if you prefer these features, simply do not update.
