Don't know anything about'm other than reading about'm, but... I wouldn't put a trike in the same category as an e-bike...

Just my prejudice, maybe but– I don't see an e-bike as being exercise; however... certainly a purposeful option for someone going to work everyday and needing to get there by a certain time and not being able to afford a car... I see a lot of kids going to school on an e-bike... not everyone is expected to walk home after a day's school in all kinds of weather for a mile or two and for a latchkey kid or for the folks who could care less, an e-bike sounds like a good idea.
