The 'KillaJoule' is the world's fastest electric motorcycle - Motofire

The ‘KillaJoule’ is the world’s fastest electric motorcycle

Built by Eva Håkansson, this electric streamliner has reached 270mph. So far.

Back in August 2014, the KillaJoule became the world’s fastest electric motorcycle and the world’s fastest sidecar motorcycle of any kind when it hit 241.9 mph at the Bonneville Salt Flats.

The ‘of any kind’ part of that last sentence is important here, because this was the first time since 1899 that an electric vehicle had become the fastest vehicle of any type; including internal combustion.

The irony being that back in 1899 the world’s fastest vehicle then was in fact, also powered by batteries.

In August of 2016, Eva and her electric bullet-bike broke her own record by setting a speed of 248.700 mph (400.2 km/h)

The technical data for the bike looks complicated, but a quote from Eva on her website will put everything into a little perspective,

“The KillaJoule may look complicated, but if you think about it, it is just a giant cordless drill with wheels!

It has a battery  with the same kind lithium-ion chemistry that you will find in cordless tools, a motor, some power electronics and a throttle. And wheels, of course. Except for the wheels, it is pretty much the same components in as in a cordless drill.

A 400 horsepower cordless drill….. 😉”

The actual specs show that the machine isn’t powered by a supercharged Dremel though, but rather an EVO Electric AFM-250 Motor that is capable of producing 500 horsepower. These are provided power by  lithium Nano-Phosphate, 400v and 19kWh batteries, whilst two Rinehart Motion System PM100 controllers keep all that power in check – limiting everything to 400 HP.


The rest of the motorcycle is a little more traditional, with a 19ft long with a Chrome-Moly steel tube frame, the suspension is Springer style at the front and ‘classic stereo’ at the rear.

And it’s all built for one, single purpose according to Eva, ‘to show that eco-friendly can be fast and sexy’.

For a fantastic overview of the project, Eva and her KillJoule are currently featured on Engineering.com. It’s well worth a read and gives a wonderful breakdown of some of the technologies used within the world record breaking machine.
