As others have pointed out, a normal rear derailleur can be locked in place with the limit screws, or with a dummy cable, to do the same job properly at a lower cost.
Got it, gonna test the locked derailleur on the gary fisher...ordered a 13T single speed cassette kit last night.

I think a better approach would be to convert 7 speed beach cruisers. The only mod would be to move the shifter to the left handlebar, upside down, or put on a friction shifter.
If I was starting from scratch, that might be one of the options I would look at for casual riders just riding the downtown waterfront in style...in rainy Portland where the metro area is spread out over 30 miles and 1,100ft of possible elevation changes, and a massive number of folks use their bike as their sole transportation (along with the light rail system, myself included), I don't think it's a good fit. Who I am looking to target are existing metro-area commuters who are low-budget but haven't switched to electric because they can't find a quality 3-season package for their money without DIY (most people are afraid..."I might electrocute myself!"), don't want to replace their ride, and don't want to lug 60lbs up hills if they run out of juice.
My thought is: after torture testing the MAC for a year and a half and tearing it down multiple times, I feel like I have a good idea about what works and what is unnecessary in an electric commuter bike around here. I already have a two page list of people interested that have stopped me to ask questions while I'm riding around on mine, so I have a decent survey sample of what they want and are able to spend. You're right...the big hurdle with customers I think will be in convincing them that all they need is their left 3-speed shifter to handle whatever, but I think once they demo it (if I get everything right) they'll understand less is more quickly.
Simple, reliable, powerful, cheap, is what I'm going for (half twist throttle with on/off key and built-in volt meter, 3 speed switch, custom program 6fet infineon, MAC, 11ah LG on downtube, parts teardown for waterproofing). I want to do a starter run of 5 26" rims and 5 700c rims...should put me back about $550 per complete kit after shipping. If demand increases and I can order 30+ setups at a time I should get that down to $450. If I can build a reputation, then I'll think about LLC and getting some legaleze to offer turn-key bikes similar to how juiced started but that would take a while. The good news is Portland is hot (huge influx of transplants here in the past 8yrs, thanks Portlandia!), so congestion is horrific and more and more are biking in an already big bike town.
Thanks for all the suggestions folks...I'd love any more sage advice you have about getting started as well Dan, it's very appreciated!
