Is this the world’s fastest electric bike?

Challenging the perception that electric bikes are dull and slow, Swedish engineer Eva Håkansson is attempting to set a land speed record for electric motorcycles of 300mph in her KillaJoule electric motorbike.

Designed and built by Dr Håkansson and her husband, the 400hp KillaJoule is powered by lithium nano-phosphate batteries and the 5.6m chassis is built from chromoly steel. Despite its bold aims, the KillaJoule’s engineering is ultimately fairly straightforward, as Dr Håkansson explains: “If you think about it, it is just a giant cordless drill with wheels! It has a battery with the same kind of lithium-ion chemistry that you will find in cordless tools, a motor, some power electronics and a throttle. And wheels, of course.”

Created, as Dr Håkansson puts it, “to show that eco-friendly can be fast and sexy”, the KillaJoule already holds records from previous attempts at the world-famous Bonneville Salt Flats in 2014 and 2016. It is also the world’s fourth-fastest battery-powered vehicle of any kind.
