You are not going to believe it but I just found out some people drive cars for fun. They even destroy forests with their trucks for fun. I would much rather have them running around (even recklessly) on electric bikes than in their cars.
I find that my legs are much more sore when I am done riding my electric bike since I really push going up hills because I have help getting home if I am really tired. I don't save any energy for the trip home.
