Not if over 48 volts, this limit is Europe wide for safety reasons.A pedelec is legal if it has a motor rated at 250W, but do they remain legal if high voltage? Therefore 72V 4 wheeled pedelcs, or those of even higher voltage, could be viable and legal cargo vehicles?
The voltage doesn't matter though, it's not power. It's only the wattage that is power and the watts can be obtained from 48 volts using more current.
72 volts x 13.8 amps = 993.8 watts
48 volts x 20.8 amps = 998.4 watts
