For some reason, I have the urge to build an electric motorcycle and do it on the (relatively) cheap. I don't care about saving the planet, lower energy costs, or any of that other hippie stuff, I just think it would be neat to play with. The plan in my head calls for a small bike, something around the size of my KH100('cause small bikes are awesome
). Since all my RCs are electric, I've got a pretty good handle on electric drive systems. I can build my own brushless motor out of an alternator for next to nothing, and brushless controllers that are large enough are reasonably priced(in the $300-$400 range for something with regen capabilities). It needs to be capable of 60 MPH with a 50 mile range so I can use it as a work commuter, and the problem I'm running into is batteries. While I'd like to use Lithium batteries, I just don't have the budget for that many of them. All the lead acid builds I've read online only have a range of 20-30 miles with four AGM car batteries, and that's not going to cut it. Anyone have any experience with this sort of thing?
