You are right, the XS is indeed related to the speed.... unfortunatly... it goes slower Lol
Picture of the bottom should also be up there (it is for me) but there is only 1 small capacitor.
I realy hope the motor is not the problem in this matter, and i believe other people have the same motor as me, and do 45km/h or higher.
It should have more then enough power to do so.
there is 1 cable that is on the outside. i tried unconnecting it, but it didnt seem to make a diffrence. I expected it to be regenerative breaking.
But maybe i should field test it (only tried with wheel in the air.
