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 http://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

  • Superb job, I bet ...

    Superb job, I bet if you had a wind turbine or solar panel you would have free local transport for life. Congratualations on this incredible piece of engineering.

    Solar and wind would be great ideas. As an aside, Ford Motor Company recently announced they will have production hydrogen powered vehicles in the next 2 -3 years, I can't remember the exact timeframe.

    When I was young rode a "drag piped" Harley. Now I ride a nice and quiet Goldwing. Love the peace quiet, hard to find now days.

  • Solar panels that ...

    Solar panels that would charge it. Also a wind alternater. No extra load on the grid. :) Plus a hydrogen run generater would work also. There are old generater engines on youtube that would run a generater to charge it that only use a gallon of fuel in 24hrs.

  • Regenerative ...

    Regenerative braking can be achieved using the motor itself in most cases, if when you brake, the circuit cuts the power into the motor, and reverses the poles the motor becomes a generator, but this kinda thing does take a heap of mods to the throttle circuit, he could prob do it though, he got this far....

  • "Have you thought ...

    "Have you thought of using a snowmobile style pulley and belt setup? (Acts like an automatic transmission.)"

    This sounds like a CVT (constant velocity transmission) setup. Great idea!

  • "The increase in ...

    "The increase in power plant consumption if everyone converted to electric means no less pollution as the increase in power plant consumption would offset any emissions saved by the electric vehicles."

    That assumes that the additional electricity would be generated by burning fossil fuels.

    "Furthermore our power plants can not even now handle the demand for energy."

    That's because the Atomic Energy Commission was, for decades, run by politicians, not scientists.

  • Does the vehicle ...

    Does the vehicle use regenerative braking? i.e. charging the battery by momentum turning a massive alternator causing the vehicle to slow down during times of braking?

  • The increase in ...

    The increase in power plant consumption if everyone converted to electric means no less pollution as the increase in power plant consumption would offset any emissions saved by the electric vehicles. Instead of releasing Co2 from the tailpipe you are just releasing it in the increased demand of electrical consumption at the power plants. Furthermore our power plants can not even now handle the demand for energy.
