Looks like good size calculator, I'll have to measure myself and see what it recommends. The bike shop I went to Monday and the one I bought my bike from both thought the size I have would be fine for commuting. The one I went to Monday said the handlebars would probably be too close on a smaller bike.

Ya, I'm definitely going to have a torque arm. I'm interested in ebike.ca's version 4 torque arm as it looks like it'll work with the way my frame is around my dropouts, but the shipping from them is almost $20. I found that
EM3ev.com sells the same arm and it'll end up being about $15 less including shipping. I'll keep looking, but that's likely what I'll go with.
I don't think motor temp will be an issue, but I will keep an eye on it the first few times I ride it in 100F+ temps. Guys on Endless Sphere have put 2-3k watts into this motor before having any heat issues. My commute is flat besides one short hill, so it should be fine.
I should have bought my battery earlier, I don't know how I'll be able to wait after I get the motor.
