The hub is zero maintenance and torque from zero MPH. The battery pack for it cost me and arm and a leg though. It was the same price I paid for my Felt brand new. $750. Makes me shudder every time I bring it up. LOLWell thanks again but I have not so much mastered the Felts as just come to a reasonable arrangement with this one. I ditched the Felt fenders and went with Nirve but modified them a bit and then made my own brackets. The idea of tasting pavement because I like the look didn't sit well with me either. I have a little more I'd like to do on the rear but the front is solid enough that a decent sized kid could stand on it. The complex / cluttered looking brackets look at home on my bike though or at least I think so. Believe it or not one my goals when I rebuilt the bike was to simplify and de-clutter. Oh well, I guess it's a fair representation of what's in my head. Clutter.
I really like the look of the electric rear hub. Certainly something for me to consider.
