I was taught that this acceleration on each stroke has to hold true unless the (net) stored kinetic energy in the wheel is equal to the force exerted on the pedal stroke. In other words the bike slows down via friction, air resistance and rolling resistance as the stored energy is less than the exerted pedal force as some is turned into heat, etc
I'm sorry and I know that you are already upset, but this doesn't mean anything or make any sense whatsoever. Why should only KE stored in the wheel matter? It's trivial compared to rider KE. What does "true" mean? How can you say that the energy of anything is less than the force of something else? This is like comparing the volume of a sound to the brightness of a light.
