It helps to put some perspective in when saying they are heavier and more powerful. A typical cyclist can put out around 250w of power for a short duration, a US street legal ebike will do 250-750w. An average American male weighs ~200lbs, a typical mountain bike or cruiser will be 20-25lbs, a commuter type ebike will be 65lbs. A road bike, or road style ebike would be lighter, a cargo bike would be heavier. So an ebike weighs ~15% more overall, but combined with someone pedaling has 2-4x the power of a regular bike. Compared to a Tesla model 3 performance, it weighs 4250lbs, 16x as much, rated for 350kw, 350x the power. Even a Smart car one of the smallest cars in the US weighs ~8x as much and has 60x the power of an ebike.
