I'm looking through the EV Album and I'm inspired by: http://www.evalbum.com/2547
I'd like some thoughts (+ estimated co$t) on the basic components: speed controller, motor, and batteries. I've done some initial calculations (if they're correct) and I'm thinking three ~150 Ah 12-Volt PbA batteries might do the trick. I'm looking for 35-45 MPH top speed and probably a minimum of 20 miles of range. I'd like performance to be as good as or better than stock.
What are the general options for controllers? Are most set up with a twist throttle?
I'm thinking forklift motor. Will a pump motor have enough grunt?
I might do it up as a sidehack so I can put the batteries and such there, and have some cargo room, maybe a passenger.
Actually, to start I might go with a shorter range. But, I'd like the components to be able to take more power eventually.
The other motorcyclebike I like is kek_63's chopper. I didn't find a build thread or much on it.
