We have a problem with the catch-all nature of the term "e-bike" which includes both of these things.
They are, of course, entirely different machines - one a battery-powered scrambler motorbike capable of speeds up to 75km/h and the other a traditional step through bicycle which is powered primarily by pedalling, with a battery to assist on hills and against strong winds. The battery only operates when you are pedalling and cuts out at 25km/h.
