wow! thanks for the link. if i'm understanding it rightly, that is very interesting.

so does this mean that a DreamBike would have a jackshaft and one of those NuVinci endlessly variable hubs :-)

yikes! expansion chambers, springer forks, dynamo drum brakes, jackshafts... what started as a simple desire for a junk commuter bike with a little Chinese engine will be an SUV when i'm done dreaming :-(
