I think George S. can help me the most with this considering that from what i have read on this forum most owners of DIY bikes are using bbsxx. Definitely a consideration for me but I actually started thinking about an ebike using a hub motor and I am now giving that a serious re-look. I have no hills, will never be off road, am looking for simplicity. Aside from what bike to buy which I have addressed in other posts I would like some opinions on (1) does this make sense for my limited, flat riding. (2) should I consider front or rear. (3) dd or geared.
