Demo of electric motorcycle. We took a Derbi GPR-50, removed the gas motor, and installed an electric drive system. There is a web site that contains a little more information about what we are doing. The URL is www.maxdon.com. We are considering designing and selling electric motorcycles commercially. However, if you are interested in building one yourself, you can find a wealth in information on the internet. At this point, I have borrowed ideas from no less than 10 different people for my design. Some of Maxdon Electric innovations that you won't find in other bikes are 1. The onboard microcontroller (described in the latest version — see the update video) provides torque control throttle feel and gives the rider battery status information 2. An RC-delay precharge circuit for the main contactor 3. A unique compact layout and mounting of the electric drive system
