Electric bikes have their own environmental and health advantages. However, riding for long distances – if you’re not a pro – or when planning to go off the tarmac, an e-bike is not the best companion. Before you look for a capable pickup truck – that’ll never be the first choice for a city commute
Probably continuous vs peak power. I’ve seen brands advertise this very unethically - Lectric has done this. “Ours is 1400W, the competition is only 750W!”
Or advertising the peak in-rush current or whatever instead of the continuous allowable power? A 750W motor probably pulls 1400 watts for a split second as it starts up under load.
