In practice, the type of bike I ride (a Rad Runner Plus) is optimised for comfort under power rather than efficiency. Power will come almost entirely from the 250W motor with maybe no more than 50W from me. Once the motor tops the bike out at 25km/h, I'm not going to be going any faster without a major change of stance, gear, and expectation of exercise.

Athletic biking is for the weekends :)
