The principles are altering a bit although and there’s a more recent class of cargo-carrying electric bikes that may use a motor offering higher energy output to assist their riders extra when transferring heavy masses round.
So to reply the large query: sure, you do have to pedal an electrical bike if you wish to get pleasure from the advantages of biking however with rather less bodily effort.
