Iwatani of Tokyo has recently unveiled their latest Hydrogen Bicycle that is totally green since it doesn’t emit any CO2. Tipping the scales at 31kg, this 156cm bicycle is able to move within a 45 mile radius at best in terms of assisted travel. It will be powered by hydrogen cartridges that are available from Iwatani, although you will have a lithium-ion battery (26V-4Ah) on board to help you out as well. All the hydrogen carts will come in a volume of 80nl and need to be placed in a small tank behind the saddle. No idea on whether these bikes will be mass produced, but here’s us keeping our fingers crossed!
