Does it though?

Edit: Yes it does:

“Because of the added weight and torque, e-bike systems do produce more wear and tear on “consumable” parts. You’ll likely have to replace things like chains and brake pads more frequently, and you’ll want to keep an eye on tire wear and wheel parts like spokes, which are under more stress from the torque of the motor.”

So yeah, no clue how they got to the conclusion that eBikes are more energy efficient than regular bikes.
