Hello,
The subject of the Denver Electric Vehicle Council meeting this Saturday is
converting a motorcycle to run on electric power. Location details (Broomfield,
Colorado) are on the DEVC website at http://www.devc.info.
Thought that some of the folks on this list might be interested.

Hi Steve,
My gear ratio is not as high as Jeff's. Front 12t rear 45t or about 4 to 1.
My set up is a DC brushed ADC motor with standard chain drive.
My amps measured at the battery and at the motor are equal, with a curtis
controller.

Hi Steve,
My set up is also 72 volts.
I guess I really don't understand how some of the more sophisticated
controllers reduce the amps the motor sees.

Hi Mark,
How quiet is it compared to the typical chain drive? Have you measured amps
with the rear wheel in the air (e.g. center stand)?

I had the same issues with sprocket set screws loosening up. I dimpled

That solved my problem.

I actually took El Moto for a test drive in September. First you should know

I don't really understand why the aero numbers for these 150MPH plus sport
bikes are so poor. Were these numbers measured with the rider aboard?

Hello DEVC Members,
Just a quick note to let you know
Thanks For the input Darin.
I guess in all the data I forgot some conclusions.

wheel) don't seem to be much of an issue on an electric motorcycle.
2) Despite my search for a range killer in my direct drive line the

Your approach seems valid. The swingarm mount will free some space for
batteries. The Etek will be 40#s less than my ADC, although less able to

The biggest chassis issue that I have is due to the extra weight. My chassis

One additional thought for you Parker.
The thing that I like best about this machine is that is shines this time of
year as the cold weather abates. My ICE motorcycle still has the starting
battery removed and stored. It takes about 30 minutes to fire the ICE up after
it has been sitting
I'd love to give Jim Husted at HiTorque a broken Etek and let him noodle on
how to beef it up. I suspect he would come back with a more durable motor.

Hello Darin,
I too got stoked after watching Worlds Fastest Indian. So what are the sorts
of things that would need to be addressed in order to reach 130MPH on an
