The world's fastest electric motorcycle

When they don't develop and manufacture awesome 3D printing filament, the wife-husband team of Eva Hakansson and Bill Dubé have a very expensive hobby - to design, build, and race the world's fastest electric motorcycles! Their latest design is the 1,000 HP all-electric "Green Envy", built with the goal of becoming the fastest motorcycle on the planet. Full stop.

Both Bill and I (Eva) have been into electric vehicles since long before it was cool. Bill converted a Volkswagen Rabbit (Golf) convertible to electric in 1995, and commuted back and forth to work in it for over 15 years. I was born into an electric vehicle and racing family, and I converted a motorcycle to electric together with my dad in 2007. It was the passion for electric vehicles that brought us together, and you can read that long story here, if you are curious,

Bill has a background in electric dragracing, and his 650 HP electric motorcycle the "KillaCycle" dominated the 1/4 mile for over a decade. In 2010 we decided that land speed racing was a more suitable format for us. We race to promote electric vehicles and eco-friendly technology. Yes, we are tree-huggers in all we do. I call it "eco-activism in disguise". We are environmental activists, we just chose a different way.

Land speed racing means that you are going insanely fast in a straight line, and trying to be faster than everybody in history before you. Our previous racing vehicle the "KillaJoule" was until recently the world's fastest electric motorcycle at 434 km/h (270 mph), with me as the rider. The KillaJoule was retired in 2019, and we built a new bike - the 1,000 HP "Green Envy". The ultimate goal is to go 400 mph (650 km/h). 

The Green Envy was complete and race ready in March 2020, which was the worst possible timing in modern history. The world came to a screeching halt with the COVID pandemic, and Green Envy's debut on the South Australian salt flats was delayed until 2023. In 2024, the salt flats were flooded due to heavy rain and the event was cancelled.

Tired of the weather sensitivity of the salt flats racing - and the need for more testing - made us decide to go to a different land speed event in 2025. The decommissioned Loring Air Force Base in northern Maine, USA, was the perfect place. The Green Envy finally made it to the major milestone of 200 mph in July 2025. The next land speed event at Loring is in September 2025. (If September 2025 has passed when you read this, please contact me because I have forgotten to update the website...).

My TEDxUoA talk tells you all about racing to save the planet:

Land speed racing is also what lead us into 3D printing. We needed custom parts, and 3D printing was the way to go! I didn't think Bill would go along with such an expensive purchase (about NZ$3,000 or US$2,000 at the time), so I made an elaborate plan to sell my stuff on eBay like shoes and handbags to save up for it. I carefully selected items to sell, counted up the expected sale price, and almost got it all to add up.

I presented the idea of buying a 3D printer to Bill, and before I even got to present my funding plan, Bill said "Sure! Sounds like fun!". A couple of weeks later we owned a refurbished Lulzbot TAZ5. We had no clue that it would change our lives forever.

As soon as you have a 3D printer, you want a larger one! We realized that 3D printing would allows us to print complex curved airfoils for the KillaJoule, such as the cowling for the sidecar. 

With large-scale 3D printers costing tens of thousands of dollars at the time, we realized that the only way we could afford one was to build one ourselves. The Lulzbot open source design was a perfect starting point. A winter later, the large scale derivative of the Lulzbot was complete with a print volume of 750 by 750 by 800 mm. Bill named it "3DD", pronounced "three double-dee". Eva loves to make people a bit uncomfortable by cupping her hands in front of her chest and proclaim with a laugh "It wasn't named after me". :-D

A sidecar cowling for the KillaJoule was one of our first large prints. It took 6 days...
