let us know how this works when you finally get to ride it, it would be really cool if the hub gear works.

If it didn't, of course, i was thinking you could cut off the crank arms, hook the jackshaft strait to your crank gear and use a centrifugal clutch to get you started...

Still i got my fingers crossed for you John!
I successfully blew up a shimano nexus 3 speed, i went down a dirt road on a hard tail bicycle and just did 20... bent the shaft and blew out the bearings ... and broke a chain in 3 places. Then again I also blew up a normal derailleur(it wrapped around my sprockt!).... I guess the sbp shift kit wasn't designed for abusive teenagers!
