It was suggested I look into electric bicycles for my commute to work. I looked into this when I got the job last year, but it never went anywhere. So, I am now looking into it and am wondering if I could get some more info.

My commute is roughly 7 miles one way, there are some decent hills. I am not in the worst of shape and believe I could fairly easily work my way up to biking it, but I do have a bum knee from ACL surgery about 10 years ago.

So, what is out there? I know there are conversions out there as well as production bicycles. Suggestions?
