I'm not sure if the park is factoring in the ebiker can travel further because of the motor assist compared to just traveling faster. The ebiker might be doing more laps because they are not as fatigued compared to the regular MTB riders? I would have to load up my pedal bike on my SUV, drive down to the single track trails near the Rio Grande river, ride for few hours, and load up and head home. Now, I ride out my garage to the same trails, ride 2X longer, and have enough juice to ride home. I'm still averaging about 10-14 mph on the trails with either bike; but, I can have more track time with the ebike before my energy level drops.
