I am considering getting one to do a 10 mile commute, along fairly flat roads. I was thinking that the power would help me on windy days, when cycling into a head wind would leave me gasping and sweating (no showers at work). But mostly I would expect to be pedalling, and could ride against the wind on my way home if necessary.
I know that most electric bikes can be ridden without the power, but is that a big compromise? I'm not sure how often I'd use the power. Would it solve the problem for me, or is it just a lot of unnecessary weight and expense, given that it would not be used on every journey?
