Yamaha has flaunted its eco-friendly commuter bike designs at the Tokyo Motor Show.
The HV-X concept, which is designed on specifications of a typical motorcycle, is a compact hybrid-fuel machine.
The motorcycle giant, which has not revealed any details about its HV-X, has assured the green machine will provide "high-quality acceleration and pleasurable cruising performance".
The model displayed at the event showed how the hybrid engine can be squeezed inside the HV-X's unique frame design.
Yamaha's EC-03 sketches for the project resembles a futuristic Brompton folding bicycle. The 100% electric-powered city commuter is said to be light, smart, clean and silent.
The Yamaha EC-03 has a lightweight aluminium frame, a 0.6 kW motor, and is powered by a slim lithium-ion battery.
It also features a charger built into the bike for simple recharging from a three-pin socket at home.
Yamaha says that the performance of the motorcycle will resemble a 50cc moped, making it an electric scooter for the new century.
