Even more Electric Motorcycle questions?

["Fitzgearld, Fredric" <fredric.fitzgearld@intel.com>]

You know...

I have a '76 Z1 Kawasaki that needs an engine.  I was going to build another
engine for it (at some time in the future) but I would consider converting
it to electric.  However, I'm looking at a house that is about 15-20 miles
from work.  That means that I need a "working range" of about 40 miles.

Now, it's my understanding that there needs to be a range of about 60-80
miles to make the 40 miles easy on the batteries.

Other then adding a sidecar, can any of you think of a way to make this
possible? 

I was thinking...  IF I cut out the crank and mounded the motor to the 5-sp
tranny, would that help any?  That can be done if it's worth the trouble or
a gain in range.

Thanks again.
