What do you mean by changing motor speed? It has a cadence sensor so should work like normal ebikes. Pedal faster for more speed, stop pedaling for less speed.
The web page tells that the app can be used to switch between eco/normal mode but that seems to be the extent of it.
Power, not speed. Exactly because these kinds of kits don’t have a way to measure your power (effort), they need an external way to tell them how much you want them to be helping. So there are power levels (often 5) that change the power curve of the motor when it’s helping, usually helping more at lower speeds (likely uphill) and then fading out at higher speeds.
