By themselves, motorbikes are considered to be more energy-efficient  than four-wheeled vehicles. However, Abarth plans to up the ante with  its zero-emissions design using a hubless construction. What’s  interesting is that the motorcycle, dubbed the next-generation racer  (NGR) is designed for acceleration, speed and performance. All that in  an energy-efficient and environmentally-friendly design.
The Italian brand usually produces  racing cars and tunes production cars and motorcycles to racing specs.  This time around, they have designed a motorcycle from ground up using  an aerodynamic design with ducts meant to drive in cool air to its  battery and electric motor.
The hubless technology gets rid of the drive chain, which is usually a  source of inefficiency. This also enables the NGR to use regenerative  braking–the kinetic energy from slowing down is used to drive power back  into the batteries.
And if you notice, there are no gauges on the concept bike. Abarth  intends to project performance data directly onto a heads-up display on  the helmet’s visor.
