Re: what would you do differently
44 back sprockets are just too big and heavy for me- the motor revs and revs and the bike goes nowhere-
I like a 36 I bought for the first build- faster cruise, keeps noise and vibrations down- uses less chain too and aids frame clearance
The 41 I got with the second kit is a little better than the 44 and really more acceptable right from the box- it's lighter in weight, and dished and uses a few less links.
If you geta 44- maybe you can get a smaller sprock before building and having to switch
