ERocket
Is it a bike?

Is it a motorcycle?

Is it a scooter?

or is it some sort of hybrid of all of the above.

If you guessed a hybrid, you'd be correct.

The eRockit bike is the invention of Berlin Based Stefan Gulas and according to The Local.de:

"The lanky 38-year-old Austrian has managed to meld slick biker styling
with cycling sensibility in the latest version of what he’s dubbed the
eRockit – a pedal-powered bolt of lightning on wheels.

Formed in late 2004, his now 12-man company builds a variety of bikes,
mixing the aesthetics of a motorcycle with a battery motor and adding
bicycle pedals to come up with a totally unique two-wheeled vehicle.
Powered by electricity, the “human-hybrid” still relies on pedaling to
propel it forward at speeds of up to 80 kilometres (50 miles) per hour.

“The idea was to build a machine like a motorcycle, which can
out-accelerate cars,” Gulas said. “It’s our own system. It’s a new technology not implemented
anywhere.”
