Hey there, John!
Yeah, I remember pedal car type bikes (trikes and quads, most of them). Rhodes still makes the iconic machine, I think- The Rhodes Car. As for electric assists, or ebikes, I see a lot of them down here, but for every one person using them correctly, I see ten that aren't. (Too many lazy people in suburbia, don'tcha know.)
From a
permaculture point of view, you have to ask about how the ebike is charged. If you're charging it off the grid, it's simply an external exhaust moped. If you've taken the time and effort to set up a photovoltaic array or wind turbine to charge your ebike, you get extra bonus points and an E for effort!
As for me, I see ebikes as a self-fulfilling need: They are so heavy, with the batteries and motor and all, that they do need those batteries and motor and all. I have several bikes that weigh under 25 pounds, but are cetainly sturdy
enough to do all I ask of them in this suburban environment, no motor required. My confession: If I get to the point that I can't pedal, I have a motorcycle as well as a motorscooter with a sidecar. To me, if you're gonna have a motor, HAVE A MOTOR.
My bikes don't have motors, except for me. For now.
