The e-scooter travels at a maximum speed of 25 km/h in Sport mode on a straight stretch of road When travelling downhill, it can reach speeds of up to 40 km/h, depending on the route

You can also change this soon via Xiaoflasher Z.b so that it is legal if you want up to 20 km/h

Is there a speed stabiliser?

Does it have cruise control so that you don't have to keep your finger on the accelerator all the time?

Yes. Never goes over 25 km/h.
