I ride my electric tricycle for around 75% of the time because it gets used for shopping and going to the hardware store etc etc. My tricycle is my car replacement for around the town type tasks and I've got it geared so I can pedal along too and get some exercise without wearing myself out too fast.
Because I like bicycles I own a small fleet of elderly English bicycles and these get ridden in between times for the sheer fun of it.
Having a motor push or pull you about is certainly helpful when it comes to carrying large loads, but I still enjoy the buzz I get from riding one of my old lightweights or ladies sports bicycles. When I walk I need a walking stick, but once I'm on a bicycle I'm free and I can go fast without missteps or wobbles
