Electric mountain bike questions

[BL_RV0]

Hey guys, I have a 2008 Giant Rincon as my town cruiser and I've had the idea of electrifying it for the longest time now. I was hoping to do a HV setup with some of those ebay A123s that Neil found a few days ago and a HC outrunner. But with my gear ratios and too-high motor RPMs, I've decided that unless I run a hub motor (too expensive, lol) I couldn't do this. So, my question to you is, would a turnigy 63-74 170kv outrunner, 150a 6S lipo esc and, say, 6S4P A123 be adequate for a ~35lb fully loaded bike with a 110lb rider suffice? Or would it run too hot? FWIW: I'd like to get ~30mph out of the bike.
