The ebikes that I have ridden stop adding power at speeds above 20 mph.
And the bikes themselves are heavy, not very aero and lacking in good gearing.

I would find this extremely frustrating on descents and extended flat sections.

My current commute would take about 10 minutes more (each way) on an ebike.
It would also cost an extra $1,000/year.
And would not provide good training.


Who would prefer ebike over a real bike?
Answer- people who are less interested in training and physical activity, and who have more time and money available to them.
