I ride my e bike because it lets me go as fast as I want even with a pannier on back. I can get the same workout on all for assist levels but just go faster. Yesterday I did 40 miles kept my heart-rate at 130 average 16.5 mph average with lots of climbs and down hills. it just makes it more fun. if I am going to ride a analog I am going to want to keep the weight down. I put 197 miles on my e bike last week and kept my heart rate up the whole time.
