[ElectricMotorcycles] bmw conversion update

[SteveS]

Well, I actually rode the BMW under electric power today! It took a 
pretty heavy hand on the throttle to get her moving though, so it looks 
like I need to gear it down. Too bad, as I had made up a pretty elegant 
connection between the motor and drive shaft and the motor and batteries 
all fit in nicely. I guess the easiest thing will be to find a 
transmission, but that will require relocating everything. Oh well. But 
it was sweet for those few seconds; smooth and quiet.
