Nice work! What controllers did you use? Are those sensorless? Twin motors are the way to go on small scooters if you want some power.

What kind of top speed are you getting?

Both motors hall sensor with noname controller from Alie. 36V 16A and maximum speed 35km/h
Maximum range was 35+km , many hills aound so up, down, up, down...but mi BMS died with almost all cells. Now 28650 Liitokala 10s2p 10ah aroun 20+- km range...
It was a good project, but now its time for something more universal than this.

You might get some ideas by looking at some of the nicer factory made scooters like this:

Acceleration is very good, one motor doesnt have enought power, its a bit lazy, only for flat road, but both of them its really funny.
Sorry no video, maybe in few daye, weather starts to be much better
