Banshee, I wanted to add-on here. I'm looking for a very similar thing. Information is very hard to come by and no bikes seem to have everything I want. Maybe we can help each other search.
I'm looking for a FS IGH MTB with Gates drive and 27.5/29" tires, unregulated top speed class III (throttle/pedelec). No bike has the FS Gates except for R&M and one other German make I heard of on here (with proprietary belt tensioner). However, I found this Luna bike which cuts into most of my requirements (5-sp. SA hub, unregulated max RPM's). As far as I understand it, the only way to get this is to be looking into max off-road bikes, since touring and commuter designs are subject to regulations and speed governors. The other way is to hack the speed sensor on some motors, although I'm sure that would be a few night's worth of time and money.
I work nights on the east coast, so I'm doing city commuting with some trails on my route. Going through rain and snow, largely empty and unpopulated since I'm biking exclusively at night. Need to cover 30 miles a day, so I want the speed and suspension..
