It's not just the motor. The frame gets beefed up to handle the higher forces. Generally wheels also get stronger, as does the drivetrain. The main weight penalty is the frame though. As for price, I got a decent normal bike around 600, and would expect to pay 3000 for an equivalent e-bike. For the 10x I did conflate e-bikes with 'speed pedelecs' which are not really bicycles anymore.
