How much does air pollution cost the U.S.?

In practical terms, while ebikes may have a slow top speed, they move through congested areas much more quickly, so for trip-substitution purposes, the efficiency is apples-to-apples. More direct routes at steady speeds is a real benefit to ebikes.

Much of the efficiency benefit is from the lower drag due to lower speeds, but if the purposed served is comparable, then it's valid. Just depends on what you're looking at.

FWIW, even at 30mph, ebikes are over an order of magnitude more efficient than a Model 3 at 70mph (<28 vs. 280 WH/mile). Zero (electric motorcycle) states 180 WH/mile at 70mph.

Agreed. That fits with my info. Pack a Model 3 with 5 people and go 30mph, and the efficiency per person is about the same as an ebike.

If you go steady speed the lower Cd and higher efficiency of the drivetrain might actually make it more efficient than the bike.
