Thanks for the info. I knew weight would be the enemy. Since my parts bike isn't complete. I planned on running only the tail section plastics, creating a faux tank from fiberglass, and only installing a small windscreen (cruiser style) on the front. If it's not required for operation. It'll be removed/cut off/drilled/or replaced to save weight.
I'm thinking the mounting brackets for the motor and batteries will be made from steel. But any other mounting will be alum. for weight saving. I also plan on removing any unused mouting, and drilling what I can to reduce the frames weight. Another thing I'm thinking to converse power is to change all the lights on the bike to LED's and a HID headlight. Another thought I've had due to the range needed is creating a hybrid motorcycle. Using a small generator. On Tue, Apr 1, 2008 at 9:49 AM, Jeffrey Blamey <[EMAIL PROTECTED]> wrote: > The 250 is a good start because weight is the the electric vehicle > enemy.
