Pretty cool.  I can see that converting a conventional motorcycle has it's limitation, like the frame not being the right shape to place things.

The lead batteries were only a 36v set up, right?  That would explaing why the power went up with the next battery.

I am going to start a conversion, possibly similar to yours, is there a web site with more info on your conversion?  What motor and controller did you use?

Hey Cavi, I should have been more clear. That is not my bike. I found the videos on youTube.

Skadamo,

I'm one of the designers/owners. The bike is currently sitting in my garage so I guess I'm the owner!
