OK, so stupid question, but isn't the whole point of cycling "getting some excercise"? And isn't the "going up hills under your own power" the most important part of it?
I haven't cycled in years, but I have done multiple 100 mile runs and cycled from London to Paris the hard way.
eBikes sure look cool though, but I can't help thinking they are missing the point....
You still put the effort in - My heart rate on a c30 mile ride, at my age my max heart rate is supposed to be c160bpm
