What specific techniques or riding styles tend to maximize an eBikes power output and speed, and are there any particular cadence, gear selection, or body positioning strategies that can help riders optimize their eBikes performance in different terrain or conditions? For instance, do riders who adopt a more aggressive, attacking style tend to get more power and speed out of their eBikes compared to those who adopt a more conservative, endurance-based approach? Are there any specific muscle groups or biomechanical factors that come into play when trying to optimize eBike performance, and how can riders best train or adapt to get the most out of their eBikes?
