KillaJoule is the world’s fastest electric motorcycle with a top speed of 270 mph (434 km/h) so far. Builder, owner, and rider is Eva Håkansson. The only purpose of this 19 ft. (5.6 meter), 400 HP, sleek motorcycle is to show that eco-friendly can be fast and enviable. You can read the entire story how… Continue reading WHAT IS KILLAJOULE?
I often say that KillaJoule is a “giant cordless drill with wheels”. What I refer to is of course that it is battery powered, but also that it is very simple at a conceptual level. Just like a cordless drill, it has a battery, motor, a throttle, and a bit of electronics in-between. And wheels.… Continue reading UNDER THE SKIN
Want to make history? Want your name on the world’s fastest (electric) motorcycle? Want a super cool 3D printed scale model of the KillaJoule or Green Envy? Want to join a world class racing team?

I-just-set-a-new-world-record-selfie. 🙂 This is how happy I was after a 251.255 mph (404 km/h) run at the Bonneville Salt Flats with pure battery power at Bonneville Motorcycle Speed Trials on August 30, 2016. The final world record became 248.721 mph (400.278 km/h). That made it the world’s fastest electric motorcycle, the world’s fastest sidecar motorcycle,… Continue reading RECORDS & AWARDS
KillaJoule would not be the world’s fastest electric motorcycle, and Green Envy wouldn’t be on its way, without these great partners that have supported the projects in different ways. We can highly recommend their products and services. Do you want to join this winning team and help us make history and get your name on… Continue reading PARTNERS & SUPPORTERS
“How does it feel running for a speed record?” That the second most common question I receive. The most common is “How fast is it?”. The speed question is easy to answer, the other question is much more difficult. The drive itself is really short, just a few minutes, but can be quite an experience.… Continue reading How does it feel setting a record?
The weakest link in all wheel-driven speed record attempts is a surprising and obscure detail – tires! Tires can be one of the main points of failure on all vehicles, but are specifically troublesome on extremely high speed, wheel-driven vehicles. Therefore, we are literally re-inventing the wheel for Green Envy! The very fastest cars are… Continue reading RE-INVENTING THE WHEEL!
Several of the parts on the KillaJoule are 3D printed, and even more of them will be 3D printed on Green Envy. The largest 3D printed part on the KillaJoule is the aerodynamic skin for the sidecar. You can read more about it below. We are also experimenting with a wheel with 3D printed rubber… Continue reading 3D PRINTED PARTS
We all love action figures, but it is rare to find any that are engineering-themed. However, if you have access to a 3D printer, you can print your own “engineering action figure set” with the KillaJoule and myself. 🙂 Both files are actual 3D scans of me and the KillaJoule. Click here to download a… Continue reading 3D PRINT YOUR OWN KILLAJOULE
KillaJoule as “LEGO™” This KillaJoule model compatible with the popular LEGO™ toy system was designed by Urim Chae, one of my first year engineering students at the University of Auckland. The 562 students in my first year course “Principles of Engineering Design” (ENGGEN 115) were in Semester 1 2018 assigned to design an accessory compatible… Continue reading FAN ART
