Neo is created after three years of research, development and design. Actually it is a 250cc trike, with a built-in toilet for a seat.

The bio-gas that it uses comes from the Shika-oi, in Hokkaido where waste and household water are converted to methane gas via fermentation. The methane gas is then converted to bio-gas by purifying. The bio-gas is what ends up in the bike, so there’s no actual manure anywhere, but it’s a fun design that gets the word out about alternative energy.
