Thank you ALL!! I love the feedback. I guess I need to clarify what I want to do. I want power assist to help me get to work without breaking a sweat. It's nearly 8 miles one way, lots of hills, stops and starts and plenty of streets without bike lanes. Totally doable for a couple of days but after 4-5 I really start feeling fatigued, and I think it makes me really lazy on weekends. I also hate sweating as much as I do by the time I get to work.

With that in mind would the following hub conversion kit be okay for my Schwinn Conti or Windsor Oxford?
