I am an MTB nut myself and would love to see one of these kits built up on a real quality MTB frame. With great braking I think I would take my motorbike many strange and exciting places indeed..
I think current 9 speed and older 8 speed cassettes might have too much dish (as was my problem with sprocket hitting frame) Way old seven speeds or singles I imagine would be best.
Years ago, when I was hardcore into mtn biking (20,000miles/year) I had dreams of having a detachable engine I could stash in some bushes at the bottom of tahoe, drive up, ride down Mr. Toad's Wild Ride or the Flume trail, then hook up the engine and motor back to the car. (This was after my riding buddies either moved, married, and/or had kids and stopped riding. Five years of solo riding sucked. I haven't ridden in six)
So yeah, a mountain bike with a throttle rocks!
