you wouldn't take a Porche 911 turbo to go rock cralling in Moab, and you wouldn't take a lifted rock crawler Jeep to race in La Mons.
Like I said, I ride some pretty big hills around here and it works great. I also don't see why you would think you need clean road conditions. I ride on dirt, gravel, pretty much all conditions except wet (It really, really does suck in wet). I will say though, if I intended it to be a true off road bike I would choose a different drive system just because of the wet issue.
I just wish I could get some people on here to try my bike. I think they would be surprised. A local guy with a WE kit that tried it and was shocked. He now wants me to help him build a second bike. Some of you guys with super high power wouldn't be impressed but I only have around $125 in my motor, batteries, and controller. And for me, cheap is kind of the point of having an electric bike.
And actually, Porsche made some pretty good rallye cars. http://www.autoblog.com/media/2006/07/porsche-959-rally-dakar-dusty-resized.jpg
The issue in the past has been with really cheesy friction systems. It's a low cost way to make an e-bike so companies that made them used crap motors and cheap parts. From what I've seen on the internet, people that make their own friction system tend to go the cheesy route too. It' usually a non-freewheeling roller just hanging off a junk motor.
And don't get me wrong either. I'm just enjoying the conversation, I don't want to get in a big debate over it. I do totally understand why people don't think it would work. It just seems too easy and 'ghetto'. That's ok though, I like being different and most important, cheap. lol
