Its top speed is 165km/hr, it can do zero to 100 km/h in just four seconds -- and it plugs into the wall for charging.
Sytse Tacoma, a young mechanical engineer from Blenheim, has designed and built his own electric road bike. It costs just $1.50 to run each week and Mr Tacoma reckons it has the torque to challenge a Harley Davidson.
It's one of just a handful of electric road bikes certified to cruise New Zealand roads. You can't buy them in shops yet.
The bike took Mr Tacoma two years to build, financed through a $20,000 loan from his parents.
Mr Tacoma's bike is powered with the equivalent of 8000 cellphone batteries, but while he was building the bike, battery technology advanced significantly.
Batteries have halved in size, lasting-power has increased and charge times have dramatically reduced.
