Neat. But these things never really seem to catch on. The ROKON has a cult following because of its wierdness, history and unique mud and swamp capabilities. It seems like a good idea but somehow just doesn't hit the target of what alot of people want or feel they need.

In the early '90s someone had a similar power transfer idea for mountain bikes that used a cable in a curved tube. It was light and actually worked pretty well, but there was friction and additional complexity. On a bike you need all the power efficiency you can get, and this thing didn't help traction enough to outweigh its friction cost. Gear driven might be more efficient but is likely to add some unwanted poundage, especially burdensome when climbing where AWD has it's biggest benefit.
