"E-Bikes are relatively expensive. So if you buy an E-Bike you're probably relatively determined to actually use it." Seems like you have the blueprint for the "perfect" counter-study: compare e-bikers only to people who spent about as much on a conventional bicycle and you select for moderate fitness nerds who will routinely output more power than e-bike and e-biker together and spend many hours per week training. The results will go through the roof in favor of conventional bikes! Utterly skewed, but nominally apples to apples.
