If the outside diameter of your bearings is 28mm then you can switch to standard 28x12mm mountainboard bearings.
This has nothing to do with the trucks, only with the deck. I would spend 25£ more and buy the Holypro deck, much better for electric MTB and no worry about cut outs.
I recommended the Matrix II trucks because they don’t need to be cnc machined like Trampa’s for gear drive. I would buy additional orange shock blocks as well but that depends on your weight, too.
