This is a great How to, on Converting a Motorcycle to Electric Drive. Much of the info can be used for Electric Cars too. I found allot of other interesting Pages in the links too. So, I will Post them below...

Build Your Own ELECTRIC MOTORCYCLE

OVERVIEW

The finished project is a 1981 Kawasaki KZ440, converted to electric. It is powered by four Optima Yellow Top sealed (AGM) lead-acid batteries, that drive a Briggs & Stratton Etek electric motor. The speed of the motor is controlled by an Alltrax brand "AXE" programmable controller that can run at up to 48 volts and 300 amps. Contrary to popular belief, and electric motorcycle is NOT silent, but is CONSIDERABLY quieter than a typical gas cycle.

The cycle is GEARED to 45 mph, has fairly good acceleration, no clutch or transmission. There's no oil to change, to mufflers to rust off, no air filter, no carbs to tweak, and no gasoline. I designed it for primarily city riding. The top speed and acceleration could be easily changed by swapping out a $20 stock sprocket.

The cycle recharges from the wall, through a renewable energy program, and if there is a blackout, I can actually run my house off my electric motorcycle! In the future, I hope to expand my system to include charging the cycle with photovoltaic solar panels.

In this Instructable, I'll walk you through the work required with the motor, batteries, controller, and mounting all components, including showing you some low-tech paper and cardboard "CAD" tricks.

Your Project
But what do you want? You might not even know yet. I always encourage people to take a look at the EV Album. It's an on-line listing of mostly home-converted electric vehicles. Each listing shows the make and model of the vehicle, the cost to convert, the speed and range, and other specifics of each project. You can also search by type of vehicle or brand name.
For example, if you go to http://www.evalbum.com/type/MTCY , you'll see a wide variety of electric motorcycles. Different brand names, lithium and lead-acid battery types, and a wide range of costs of conversion. Likewise, if you want to see Scooters, Mopeds, and Minibikes, you can visit http://www.evalbum.com/type/SCMM

Give some thought to what cycle you would like to convert. Do you like sport bikes? Great! They have a lightweight and strong aluminum frame! Do you like standard? Great! There's lots of those out there and you can show off the motor and batteries. Hang out at biker events with your unique ride!

If you aren't sure what to expect in terms of range per charge and top speed, don't worry, online calculators can help you out.
