Welcome
I am more glad to have you here than I can say. I've often wished that more GEBE site reviewers were on MBc, since they represent a considerable amount of experience.
But I'm especially glad to have *you* on board, because your review was the inspiration for me to try and GEBE-ify my own Elektra Townie 3. I eventually abandoned the 3 speed as too hard to GEBE-ify and purchased the Elektra Townie 21 with derailluer.

I have very often wondered about your wheel building experiments and I hope, over time, you will start a new thread and take us through your saga step by step, with all the exhausting details. The issues that you've encountered have come up quite a few times on MBc, and many of us could benefit from your experience.
I still have my Townie 3 speed (like you, I love the Elektra Flatfoot frames) and if I put a stronger motor on there, maybe I could get by with a single speed. But I would still have to solve the problem of building a tough rear wheel with a hub that can fit the narrow rear fork on that bike, without drilling out the hub or bending the frame!
Welcome again and I look forward to reading your rackmount thread if possible.
