Cycling is great, (in the summer at least) exercise, free travel, and a nice day out with lots of wildlife subjects for photography, however what is not so good is having to deal with enormous hills or gale force winds that pop up from time to time, so I'm looking into an electric bike to take the effort in those situations, no particular requirements really, other than something that's easy to maintain, not like those awful cheap bikes where just changing a tire is a huge chore. Does anyone have any experience with them here?
