The limitation I had with eBike hub motors is the narrow hollow axel (limited amps due to wire space/size). Example Issue: too many Amps for too long and wires melt

So, increasing voltage reduces the Amps required for a given Wattage. Something like Amps = Watts/Volts so a 1000W @ 36V would be roughly 30Amps going through whatever the kit wire size is (too much current I'm sure) and @48V it would be more like 21Amps (typically ok).

I ran quality eBike geared hub motors at 1500W continuously with 58V batteries and fat wires spliced in where they exit the axel (~26A). However, I'd suggest keeping a stock hub type eBike motor more near 21Amps max. That's 36V @ 750W or 48V @ 1000W.
