If I'm being completely honest, I don't dig electric bikes. A big part of the reason I cycle at all is because it's one of the only forms of exercise I enjoy.
Take the fitness aspect away, and (to me) all you're left with is a subpar form of transportation. Why deal with the safety hazards of cycling when I can just jump into my car and get to my destination faster and safer?
Where I'm from, the elderly are the main consumers of electric bikes. I understand in their cases, considering it isn't so easy to pedal anymore when your knees are worn out. But I feel that any young and able-bodied person should stick to pedaling, for the sake of their health and the environment.
