Love the video Hank,
Now that's a nice setup he has.
A bike like that can come in handy when a scooter is not a choice ride
(trail ride/park or where you cannot use the engine for some time.)
The only problem i foresee is when (not if) a chain derails.
Would there be a way to contain the chain due to a mishap?
Like a cover for all the hardware?
You get a pantleg caught up in that there ol chain at 30Mph, and that's going to be a bad, really bad BO-BO. (joke)
