Toby Roberts’s Concept Z Delivers Ludicrous Acceleration and a Stripped Down, Flat Track Style
There are very few journeys more tantalizing that those fulfilled on an electric motorcycle. Mating all of the vigor of a gas-powered machine with a sustainable alternative, electric motorcycles are bound to take over the market as easily as they eat up the road.
Growing up playing with buggies and bikes at his parents’ service station, Roberts discovered the world of electric vehicles in 2007. “I was building off-road dune buggies when I saw The White Zombie, a Datsun 1200 electric car that was involved in drag racing. That caught my attention and I thought that I could convert one of the buggies over to electric.”

One of the most notable features of the Concept Z is that the gearing has been carefully calculated to full maximize the torque curve. The wheel RPM and motor RPM have been aligned so that max torque is provided. This equates to 850nm of torque at the rear axle. While that sounds tremendous, it does equate to around 70hp at the rear wheel, and an expected sub-3 second 0-60mph time: Roberts is looking for a professional rider to establish actual figures – any volunteers?

The Concept Z provides a unique riding experience unlike that of a gas motorcycle. It has no gears, no clutch, and no exhaust. While some would argue that the electric motor removes a lot of what makes bikes appealing, for those who adore acceleration over everything else, the Concept Z will deliver.


Jeeze thats fugly ! Note to all EV M/C designers .
STOP making them look like an ice cooler hanging off the bottom of a cheap M/C frame
e.g. If’n ya can’t makes em look good … then don’t make em at all
Nuff said 😎
Ditto. An aesthetic disaster. The author ends her piece with, “the Concept Z will deliver”….what?
Note to PdO: Not every new electric 2-wheeler is worth covering. This one wasn’t.
